Safety instructions and measures

Referenced standards and regulations

The regulators comply with the requirements of the European Pressure Equipment Directive 2014/68/EU. Regulators with a CE marking have an EU declaration of conformity, which includes information about the applied conformity assessment procedure. This EU declaration of conformity is included in the Appendix of these instructions (see section10.3).

According to the ignition risk assessment performed in accordance with EN13463-1:2009, section 5.2, the non-electrical regulators do not have their own potential ignition source even in the rare incident of an operating fault. As a result, they do not fall within the scope of Directive 2014/34/EU.

Î For connection to the equipotential bonding system, observe the requirements specied in

section 6.4 of EN60079-14 (VDE0165 Part 1).

1.1 Notes on possible severe personal injury

DANGER

Risk of bursting in pressure equipment.

Regulators and pipelines are pressure equipment. Improper opening can lead to regulator components bursting.

Î Observe the maximum permissible pressure for regulator and plant. Î If necessary, a suitable overpressure protection must be installed on site in the plant

section.

Î Before starting any work on the regulator, depressurize all plant sections

concerned.

Î Drain the process medium from all the plant sections concerned as well as the reg-

ulator.

Î Wear personal protective equipment.

Safety instructions and measures

1.2 Notes on possible personal injury

WARNING

Risk of personal injury due to preloaded springs.

Regulators in combination with preloaded set point springs are under tension. These regulators can be identied by the red warning label on the actuator's set point springs.

Î Before starting any work on the set point springs, relieve the compression from the

preloaded springs.

Î Only use the SAMSON disassembly tool (1280-4052).

Crush hazard arising from moving parts.

The regulator contains moving parts (actuator and plug stems), which can injure hands or ngers if inserted into the valve.

Î Do not insert hands or ngers between the set point springs while the regulator is in

operation.

Î Before performing any work on the regulator, depressurize the plant. Disconnect or

shut off the external control line.

Risk of personal injury due to residual process medium in the regulator.

While working on the regulator, residual process medium can escape and, depending on its properties, may lead to personal injury, e.g. (chemical) burns.

Î If possible, drain the process medium from all the plant sections concerned and the

regulator.

Î Wear protective clothing, safety gloves and eyewear.

Risk of burn injuries due to hot or cold components and pipelines.

Depending on the process medium, regulator components and pipelines may get very hot or cold and cause burn injuries.

Î Allow components and pipelines to cool down or heat up. Î Wear protective clothing and safety gloves.

Design and principle of operation

3 Design and principle of oper-

ation

Î Refer to Fig.3

The regulator are closed when relieved of pressure. They open when the upstream pressure rises above the adjusted set point.

The Type44-4, Type44-7 and Type44-8 Excess Pressure Valves mainly consist of the valve (1) with seat (2) and plug (3) as well as the actuator with operating diaphragm (6.1), set point spring (8) and set point adjuster (10).

The excess pressure valve is used to maintain the pressure upstream of the regulator to an adjusted set point.

The process medium ows through the regulator between seat and plug in the direction indicated by the arrow on the body. The position of the valve plug determines the ow rate and, as a result, the upstream pressure.

The upstream pressure p transmitted over the control line (11) to the operating diaphragm (6.1) where it is converted into a positioning force. This force is used to move the valve plug according to the force of the set point spring (8). The spring force can be adjusted at the set point adjuster (10).

The Type44-8 Safety Excess Pressure Valve additionally has a second backup diaphragm (6.2). Upon failure of the rst operating diaphragm (6.1) the regulator contin-

ues to function using the backup diaphragm (6.2). In this case, the regulator

functions as a safety valve when the upstream pressure rises too far and opens the

to be controlled is

valve. Diaphragm failure is indicated by a red mark in the diaphragm rupture indicator (12) (point of response at approx. 1.5bar) or medium escapes at the test connection.

The Type44-4 Safety Excess Pressure Valve additionally has a second backup diaphragm (6.2). Upon failure of the rst operating diaphragm (6.1) the regulator is fully opened. Diaphragm failure is indicated by a red mark in the diaphragm rupture indicator (12) (point of response at approx. 1.5bar) or medium escapes at the test connection.

Mounting and start-up

NOTICE

Possible malfunction and damage due to adverse weather conditions (temperature, humidity).

− Do not install the device outdoors or in rooms prone to frost.

− Protect the regulator against frost if it is used to control freezing media.

− Either heat the regulator or remove it from the plant and completely drain the residual

medium after a plant shutdown.

5.2 Additional ttings

Strainer

NOTICE

Do not install a strainer upstream of

Type44-4 and Type44-8 Safety Excess Pressure Valves.

A strainer installed upstream in the ow pipe holds back any dirt or other foreign particles carried along by the medium. For example, the SAMSON Type1NI Strainer is suitable (uT1010).

The following points must be observed during installation of the strainer:

− Install the strainer upstream of the

Type44-7 Regulator.

− Allow sufcient space to remove the lter.

− Observe the ow direction.

− In horizontal pipelines with gases or liq- uids, the lter element faces downward. The lter element faces sideways in applications with steam.

− Install strainers in vertical pipelines with the medium owing upward with the drain plug facing upward.

Note

Check the strainer at regular intervals and clean it, if necessary.

Shut-off valve

Install a hand-operated shut-off valve both upstream of the strainer and downstream of the regulator (see Fig.5). This allows the plant to be shut down for cleaning and maintenance, and when the plant is not used for longer periods of time.

Pressure gauges

Install a pressure gauge both upstream and downstream of the regulator to monitor the pressures prevailing in the plant (see Fig.5).

− Remove the control line from the regulator

and seal the open connection with a blanking plug (accessories: blanking plug 83230030 and seal 8412-0771).

Once installed in the pipeline, the regulator can be put into operation.

5.4 Gases and liquids

Î Open the shut-off valves slowly prefera-

bly starting from the downstream side. Î Avoid pressure surges. Î Make sure that the air contained in the

plant (when liquids are used) escapes as

quickly as possible.

6 Operation

6.1 Adjusting the set point

Î Refer to Fig.3

Adjust the required set point by turning the set point adjuster (10) with an open-end wrench.

Note

The following open-end wrench sizes are required to adjust the set point:

− 19mm for DN15 to 32

− 27mm for DN40 and 50

Set point adjuster

Î Undo the lock nut (for 6 to 11bar set

point range only).

Î Turn the set point screw clockwise () to

increase the pressure set point.

Î Turn the set point screw counterclockwise

() to reduce the pressure set point.

Î Tighten the lock nut (for 6 to 11bar set

point range only).

The pressure gauge (Fig.5) installed on the downstream side on site allows the adjusted set point to be monitored.

The set point range can be changed by exchanging the set point spring (8) (see section7.3).

7 Servicing

The regulator does not require any maintenance. Nevertheless, it is subject to natural wear, particularly at the seat, plug and operating diaphragm. Depending on the operating conditions, check the regulator at regular intervals to avoid possible malfunctions. Operators are responsible for drawing up an inspection and test plan.

Details on faults and how to remedy them can be found in Table5.

We recommend removing the regulator from the pipeline before performing any maintenance or service work.

DANGER

Risk of bursting in pressure equipment. Regulators and pipelines are pressure equipment. Improper opening can lead to bursting of the regulator.

− Before starting any work on the regulator,

depressurize all plant sections concerned

as well as the regulator.

− Drain the process medium from all the

plant sections concerned as well as the

regulator.

− Wear personal protective equipment.

WARNING

Risk of personal injury due to residual process medium in the regulator.

While working on the regulator, residual

process medium can escape and, depending on its properties, may lead to personal in-

jury, e.g. (chemical) burns.

Wear protective clothing, safety gloves and

eyewear.

WARNING

Risk of burn injuries due to hot or cold components and pipeline. Regulator components and the pipeline may become very hot or cold. Risk of burn injuries.

− Allow components and pipelines to cool

down or heat up.

− Wear protective clothing and safety gloves.

NOTICE

Risk of regulator damage due to incorrect servicing or repair.

Service and repair work must be performed

by trained staff only.

NOTICE

Risk of regulator damage due to excessively high or low tightening torques. Observe the specied torques on tightening regulator components. Excessively tightened torques lead to parts wearing out quicker. Parts that are too loose may cause leakage. Observe the specied tightening torques.

NOTICE

Risk of regulator damage due to the use of unsuitable tools. Only use tools approved by SAMSON.
