Introduction

1.2 Description of the Models 762, 763, 765, 766 and 767 Control Valves

1.2.1 General features of the control valve

In many applications, such as pipelines, storage terminals and marine loading and unloading, it is necessary to include surge relief systems for the purpose of equipment and personnel protection. Surge pressures result from a sudden change in fluid velocity and, without surge relief, these surge pressures can damage pipes, other piping components, equipment and personnel.

These pressure surges can be generated by anything that causes the liquid velocity in a line to change quickly (e.g., valve closure, pump trip, Emergency Shut Down (ESD) closure) and subsequently packing pressure. Total surge pressure may be significantly above the maximum allowable pressure of the system, leading to serious damage to your valuable assets.

The fundamental requirements of surge relief systems include the need for fast acting, high capacity valves which can open very quickly to remove surge pressures from the line and then return to the normal (closed) state quickly but without causing additional pressure surge during closure. These valves are often required to open fully in very short periods of time, so that they may pass the entire flowing stream if conditions dictate.

Long pipelines can produce dangerous pressures when static product is shut-in between valves and thermal expansion occurs. In this situation, pressure relief will be required. Although the time of operation and valve capacities are not as crucial in such applications, they remain as key elements of safety in the system and proper regard to selection and operation is imperative.

User manual 3

Introduction

In general, all systems where pressure is contained must have some form of pressure relief, which is often mandated and regulated by local authorities. The design of such systems is dependent on a complex range of factors including, but not limited to, the potential for pressures increases, the volumes which must be passed by the pressure relief equipment in operation and the capacity of the system to contain pressures.

Typical tank and pressure vessel systems are required to release pressure without passing large volumes of liquid. Usually these systems operate to relieve vapor from the space above the liquid using self acting pressure relief valves.

Although these valves are commonly used as pressure relief devices, the nozzle size is quite small and hence, the capacity for passing liquids is extremely limited. Therefore, such designs are limited to tank and vessel protection, where overpressure is readily relieved without the need to pass significant quantities of liquid.

1.2.2 Control valve application

The Daniel Models 762, 763, 765, 766 and 767 Gas Loaded Relief/Back Pressure Control Valves are specifically designed to regulate and control maximum pipeline pressures or to maintain a minimum back pressure in a system. They have proven to be reliable, rugged and very responsive in controlling pipeline surges and pressures. The Daniel Models 762, 763, 765, 766 and 767 Gas Loaded Relief/Back Pressure Control Valves are not pilot operated. They incorporate an integral oil reservoir mounted on the external surface of the valve cylinder head, which upon installation, is partially filled with a light oil. Gas under pressure is then applied to the reservoir. The oil is a moveable barrier between the gas and the valve piston. This insures that nitrogen gas does not permeate the piston seals which would result in nitrogen consumption and the need to constantly replenish the system. A major benefit of the valve design is that all internal parts, including cylinder, piston and seat ring are removed as a cartridge assembly which keeps your line connections intact.

NOTICE

The Daniel Models do not comply with any internationally over-pressurization protection recognized codes. What the Daniel Models do is to allow the movement of an undetermined amount of substance within a pressurized system, not from a pressurized system.

1.2.3 Operation overview of the control valve

The Daniel Models 762, 763, 765, 766 and 767 control valves are normally closed and open on increasing inlet pressure. The basic valve is of the balanced piston operated design. Pressure applied to the inlet side of the piston is equally transmitted to the spring side of the piston. When the line pressure on the inlet side exceeds the gas pressure plus the pressure exerted by the spring, the moveable barrier of oil compresses the gas and the valve opens. As line pressure falls below set point, the gas pressure, added to the spring pressure, closes the valve and it remains closed as long as gas pressure is greater than the line pressure. Opening and closing speeds are controlled by a check valve mounted to the internal surface of the cylinder head as shown in Figure 1-1.

Introduction

Check valveFigure 1-1:

Opening speed is relatively unrestricted which results in very fast opening speed. Closing speed is controlled by the fixed orifice in the check valve.

These valves are normally closed and open on increasing inlet pressure. The basic valve is the balanced piston design. Nitrogen gas is used to pressurize the valve piston to keep it in the closed position. The valve incorporates an integral oil reservoir mounted on the external surface of the cylinder head, which upon installation, is partially filled with a light oil. Gas under pressure is applied to the reservoir. The pressure of the nitrogen gas, minus the 4 psi (force of the valve spring) is the effective set point of the valve. When the pipeline pressure is less than this total force, the valve will be tightly closed. As pipeline pressure increases the spring and gas pressure is overcome and the valve opens. The oil is a moveable barrier between the gas and the valve piston. This should eliminate any possibility of gas permeating the piston seal which would result in gas bypassing the piston and gas consumption.

The valve may be mounted in a 45° angle position, horizontally or vertically. Whichever orientation is specified, the oil reservoir must be vertical.

User manual 5

Introduction

Valve orientationFigure 1-2:

Closed position

Line pressure on the nose of the piston is equally transmitted to the spring side of the piston. When the nitrogen pressure is applied to the top of the oil, (which is in effect a moveable barrier between the piston and nitrogen) plus the spring pressure is greater than line pressure, the valve will be in the closed position. (See below.)

6 Daniel Models 762, 763, 765, 766 and 767 Control Valves

Introduction

Closed positionFigure 1-3:

• The oil reservoir is supplied with two sight gauges. When the valve is closed the oil

level in the reservoir will show oil covering the lower sight glass only.

• Oil visible in both the lower and upper sight gauges indicates that the valve is in the

open position.

• Absence of oil in the lower sight gauge indicates that proper oil capacity has not

been reached or that reservoir oil is leaking into the product system. (See below.)

Open position

As pipeline pressure increases, the combined force of the spring and nitrogen gas pressure is overcome and the valve opens.

Open positionFigure 1-4:

User manual 7

Introduction

• Opening and closing speed is controlled by a unique check valve mounted to the

internal surface of the cylinder head. The opening of the valve is relatively unrestricted, and response time is typically under 100 msec.

• This results in an extremely fast opening response. The opening and closing speeds

are controlled by an orifice in the check valve.

A simple routine visual check can be done to determine if the oil in the sight glass is within the recommended limits. This makes it easy for a pipeline operations team to be confident of the surge relief valves readiness.

Note

The spring in the Daniel Nitrogen Loaded Surge Relief Valve is for shipping purposes to ensure piston movement does not cause damage during shipment. This is the only purpose of this spring.

Note

Equal area on both sides of the piston allow the nitrogen pressure to be set at the actual set point minus spring force rather than a calculated percentage.

Note

Oil in the reservoir of the Daniel Nitrogen Loaded Surge Relief Valve has many advantages. It allows the piston seals to be exposed to a clean, lubricant fluid which helps to extend the service life of the seals tremendously. In addition, it should eliminate the possibility of nitrogen gas permeating the seals which will ultimately result in a leak and nitrogen consumption.

5.5 Tools required for control valve installation

Flange installation tools

Follow all best practice procedures when installing or removing flanges.

Control valve components

The control valve does not have pre-installation requirements. If installation is required for maintenance purposes, use the following tools:

• Socket wrench

• Adjustable wrench

• T-handle or extended Allen wrench

• Arbor press (may be needed for 4- and 6-inch valves)

• Retaining ring pliers

User manual 67

Installation prerequisites

5.6 Typical installation

Although quick opening of the surge relief valve is desirable, if the valve were to shut in a similar time, then further problems could occur - a valve slamming shut can produce hydraulic shock (water hammer) in the system, creating an undesirable secondary surge.

Good surge relief system design will include systems to dampen, or slow the valve, on closing. Often, this requires sophisticated reverse flow when opening and reduced orifice to limit closing speed. This design is extremely versatile and offers the user the opportunity to determine different closing speeds as required by the system when the valve is built.

Typical installation - 766 Gas loaded pressure relief valveFigure 5-1:

NOTICE

5.7 Nitrogen system

The nitrogen system must supply a constant pressure to the valve, even under conditions of varying ambient temperatures. Normally, the system will be designed to use standard gas bottles and will incorporate a control panel to regulate the nitrogen supply pressure.

68 Daniel Models 762, 763, 765, 766 and 767 Control Valves

Installation prerequisites

Supply pressure should be set at, or close to, the relief pressure required. The valve is a hydraulically balanced piston design which means that the forces applied across the piston are proportional to the pressures. This is particularly important when setting the system up: the gas pressure set point, minus the force exerted by the spring is the relief pressure for the system.

The gas tank should be buried underground or insulated to keep the gas at a constant temperature. Thermal expansion, caused by the increases in temperature of the gas will change the relief set point.

5.8 Gas plenum tank installation and sizing

The gas plenum should be buried underground to keep the gas at a constant temperature. Thermal expansion, caused by increases in temperature, will change the relief set point.

The effective volume of the gas plenum decreases as the valve opens by an amount equal to the piston displacement. The size of the gas plenum determines the percentage that the pressure relief set point will change as the valve opens. For example, a 12" valve piston displacement is 554 cubic inches from a closed to an open position. Thus, when fully opened, an equal amount of gas is contained in a volume that is decreased by 554 cubic inches. From Boyles Law, we can see the proportional increase in pressure as: P1V1 =P2V2. For example, a 12" valve piston displacement is 554 cubic inches from a closed to an open position.

Before the gas tank is sized, determine:

1. Set point (PSI)

2. Valve size

3. Allowable over-pressure (PSI)

Exponent

No consideration is given to the volume of gas contained in tubing, fittings and the top portion of the valve itself.

5.9 Nitrogen system panel

A nitrogen control panel may be advantageous if there are large variations in ambient temperature or if it is not practical to bury the nitrogen plenum underground.

The control panel can be used to provide a precise output which is used to regulate the set point of the gas loaded relief valve.

70 Daniel Models 762, 763, 765, 766 and 767 Control Valves

Installation prerequisites

The Nitrogen Supply Cylinders shown in Figure 5-2 are used as a source of the nitrogen and the control panel will use this to replenish the nitrogen pressure within the valve anytime it falls below the desire set point. Conversely if the set point at the valve is higher than the desired set point, the control panel will relieve the excess pressure from the valve.

Since the Daniel valve does not consume nitrogen, unlike competitive valves, the need to adjust nitrogen is normally due to changes in pressure due to ambient temperatures.

The nitrogen set point pressure is measured using a pressure transmitter, which can be transmitted to a remote control room. The system nitrogen set point is field adjustable by authorized personnel. A complete Emerson control valve system can be furnished that will include the surge relief valve, inlet/outlet piping, nitrogen control panel, supply cylinders and the plenum. The system is carefully designed, engineered and assembled onto a structural skid with a lifting facility (as shown below in Figure 5-2).

Topics covered in this chapter:

• External components assembly

• Oil filling procedure for valve with drain port

6.1 External components assembly

Install the external components (e.g., flanges) onto the pipeline.

The control valve is assembled at the factory. The components do not need to be uninstalled or reinstalled unless maintenance is required.

CAUTION!

SURFACE TEMPERATURE HAZARD

Installation procedure

The control valve body and piping may be extremely hot or cold.

Wear personal protective equipment appropriate to the situation when working with the control valve. Adhere to your company's safety standards and practices.

Failure to comply may cause serious injury.

6.1.1 Fasteners

The property class of the fastener is in accordance with ASME B16.5.

Stud bolt and nut types

All fasteners (nuts and studs) used in assembling Daniel control valves are made of one of the materials listed in the table below.

Bolt material selectionTable 6-1:

Bolt material selection Description

ASTM SA 193 Grade B7 <63.5 mm (<2.5 in.) High strength low alloy steel

ASTM SA 193 Grade B7M <63.5 mm (<2.5 in.) Controlled strength low alloy steel

ASTM SA 320 Grade L7M <63.5 mm (<2.5 in.) Controlled hardness low temperature steel

ASTM SA 449 <25.4 mm (<1.0 in.) Quenched and tempered steel

ASTM SA 453 Grade 660 High temperature stainless steel

User manual 73

Installation procedure

Selection of stud bolts and nuts

• Select all fasteners (nuts and studs) used in a hydrostatic test according to the flange

size and quantity listed in ASME ANSI B16.5.

• Use the shortest stud bolt that permits full engagement of the thread through the

nut by hand-tightening.

• Use only clean, rust-free nuts and stud bolts.

Note

Ensure that once the nut is tightened two threads outside the nut are exposed. The only exception is when a flange requires hydraulic bolt tensioning. The manufacturer of the hydraulic bolt tensioning equipment will specify number of exposed threads outside the nut.

• Do not use damaged or worn stud bolts or nuts.

• Do not use nuts or stud bolts that do not fit together correctly.

• Do not use nuts or stud bolts without grade or type identification.

• Do not mix nuts or stud bolts of different coatings. Different nut and stud bolt

coatings require different torques to achieve the same bolt tension.

• Do not assemble nuts with the identification hard stamp against the back face of the

flange

Stud bolt and nut storage

Remove each nut and bolt as a pair. Thread the matching nut back onto the bolt. Stack them in a fashion that will not cause thread damage.

Reuse of stud bolts and nuts

The reuse of threaded fasteners is permitted on Daniel control valves under the following conditions:

• Fasteners are clean, free of corrosion, paint, thread damage, cracks, teeth marks

(caused by wrenches) or other signs of damage.

• Fasteners are not tightened to or beyond their yield strength.

• Fasteners have not lost their coating.

Compare the threads of a used stud bolt with the thread of a new stud bolt. Finger-tighten the nut over the entire thread length of the bolt.

6.2 Oil filling procedure for valve with drain port

The oil reservoir is supplied with two sight gauges. When properly filled and the valve closed, the oil level will be half way between the two sight gauges. In the closed valve position oil is visible only at the lower sight gauge. Oil visible in the upper sight gauge indicates that the valve is in the open position or that the line product is present in the oil reservoir.

1. a) Locate NPT plug on the Cylinder Head as shown in Figure 6-1.

Topics covered in this chapter:

• Control valve normal operation

• Features and benefits

• Oil reservoir

• Applications

8.1 Control valve normal operation

All series 700 control valves are pressure balanced, single-seated piston operated with 45° body construction.

Unique design features and unit-built construction ensures positive leak-proof performance. In addition, the basic valves body and internals are the same throughout the line, simplifying spare parts inventory and reducing costs.

Operation parameters

8.2 Features and benefits

• Balanced piston principle, spring biased

• Linear valve action: Rectangular ports provide smooth linear action with maximum

flow and minimum pressure drop

• Uniform speed of response: Uniform area above main piston provides uniform

opening and closing.

• Positive (pressure type sealing) O-ring seal and valve seats are not affected by fluid

viscosity or pressure drop

• High capacity 45° (in-line) valve body ensures high capacity at low pressure drop

• Zero leakage: Contoured edge of piston provides a tight seal and ensures drip-tight

operation and dead-end service

• Unit-built construction: All internal parts, including seat ring, can be removed as a

unit without disturbing valve body and connections.

• Simple design: No diaphragms or stuffing boxes

8.3 Oil reservoir

The Oil reservoir is supplied with two (2) sight gauges. In a closed position, the oil is visible only at the lower sight gauge. Should oil be visible in the upper sight gauge, this indicates line product is leaking into the reservoir or that the valve is open. If no oil is visible in the lower sight gauge, this indicates the reservoir oil is leaking into the product stream.

User manual 81

Operation parameters

Oil specifications

Use a light weight non-detergent oil between 5-30 Centipoise based on climate conditions of user.

The oil to fill the reservoir, gas tank, pressure switch and other interconnecting pieces is to be supplied by the customer.

Opening/Closing speed

The opening speed of the valve is virtually unrestricted. Closing speed is standard at three (3) seconds from a full open position, based on gas pressure being 25 psi (1,724 kPa) above line pressure. The fastest closure is limited to 0.5 seconds at 1,500 seat ring. For closure speeds longer than three (3) seconds, the orifice size can be changed to match customer requirements. It should be noted that the calculated closing speeds are a function of the viscosity of the oil in the reservoir. Typical valve opening times are illustrated in Figure 8-1 .

Typical valve opening timeFigure 8-1:

Pressure switch

The valve will open any time gas pressure is less than line pressure. A pressure switch is recommended in the gas supply line to the valve for alarm actuation should gas pressure decrease below an acceptable operating level.

8.4 Applications

NOTICE

Back pressure control

The Model 762 is ideally suited for back pressure control and minimum pressure drop. When line pressure exceeds the gas pressure, the valve will open and follow the Cv curve for pressure loss.

Typical applications for minimum back pressure control requirements are illustrated in

Figure 8-2.

• Reference API Chapter 5 for minimum back pressure requirements of the turbine

and ultrasonic meters.

• On the end of a pipeline or any point along the pipeline where the upstream

pressure is subject to drop below minimum requirements.

• Discharge of centrifugal pumps to maintain maximum efficiency and to start against

a closed valve.

Operation parameters

Back pressure controlFigure 8-2:

Pipeline pump station by-pass

Most pipeline have booster pumps at intervals along the pipeline. If a pump station is shutdown, it must be by-passed or the entire pipeline is subject to being shutdown. The Model 766 control valve, when installed as shown in Figure 8-3, will automatically open and bypass the pump station when line pressure exceeds set point.
