Daniel™ 700 Series Pilot Operated Control Valves

Precise Flow Control of Petroleum	Features and Benefits
Products	Balanced piston principle, spring biased

Whether your application is pipeline control or blending, flow rate or pump control, Daniel has the control valve you need.

All Daniel 700 Series control valves are self-contained and externally pilot-operated, so one basic valve can perform many different functions. Multiple pilot arrangements, easily modified, allow you to choose or change valve capability as required.

Unique design features and unit-built construction assures positive sealing, linear valve action, uniform fast response and leak-proof performance. In addition, the basic valves body and internals are the same throughout the line, simplifying spare parts inventory and reducing costs.

Each 700 Series model is designed for general control applications using an external pilot for multiple control functions. These valves can be installed in a horizontal or a vertical line with flow direction vertical up.

Adjustable closing speed control prevents damage to shock pressures

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 speed with fast rate of response

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 assures high capacity at low pressure drop

Sensitive regulation - pressure from 10 to 1440 psi (69 - 9928 kPa) can be controlled within ±2 psi of set point (± 13.8 kPa)

Large internal pilot valve ports

Zero leakage - contoured edge of piston provides a tight seal and assures 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

Inherent design of valve makes it an automatic check valve - no reverse flow

Typical Installation

The Model 710 valves are typically used to stop flow on applications such as high level shut-off into storage, on-off line block control, jet fuel filter-separator control from a water detector, blend line selection and many other applications requiring remote on-off control.

The Model 710 closes upon loss of electrical power while the Model 711 opens upon loss of electrical power.

The Model 710, (normally closed), and Model 711, (normally open), solenoid operated control valves are designed for remote on-off control of flow. They are externally piped with a needle valve (speed of response control) and a strainer as standard equipment. Manual override is a standard feature of the Model 710.

Model 750 Pressure Reducing Control Valves

Typical Installation

The Model 750 pressure reducing valve is designed to regulate downstream pressure within ±2 psi (13.8 kPa) or better, regardless of variations in flow rate or upstream pressure. The pilots are balanced, single seated valves with large ports and are not affected by variations in upstream pressure.

Applications

Figure 2 - This drawing illustrates the most common usage

of the pressure reducing control valve. The Model 750 externally sensed to any point downstream, provides a sensitive control for regulation of pressure within ±2 psi (13.8 kPa). The Model 760 back pressure control valve, acting as a relief valve, protects the system if excessive pressure or surge occurs.

Figure 3 - Pipeline “A” normally provides all the product for distribution unless pressure drops below a required minimum. When this occurs the Model 750 installed in an auxiliary line “B” and sensed to the main line “A”, opens to maintain pressure and flow until normal main line pressure is restored.

Figure 4 - In this application, the Model 750 pressure reducing valve lowers main pipeline pressure to a level that is within the acceptable rating of the metering equipment. The pressure reducing valve will control a maximum reduced pressure drop of 1,000 psi = 6,895 kPa.
