General safety instructions

1

General safety instructions− The regulators are to be mounted, started up or serviced by fully trained andqualified personnel only; the accepted industry codes and practices are tobe observed. Make sure employees or third parties are not exposed to any
danger.
− All safety instructions and warnings given in these mounting and operating
instructions, particularly those concerning installation, start-up, and maintenance, must be strictly observed.
− According to these mounting and operating instructions, trained personnel
refers to individuals who are able to judge the work they are assigned toand recognize possible dangers due to their specialized training, theirknowledge and experience as well as their knowledge of the applicablestandards.
− The regulators comply with the requirements of the European Pressure
Equipment Directive 2014/68/EU, Machinery Directive 2006/42/EC,
Directive 2016 No. 1105 Pressure Equipment (Safety) Regulations 2016
and Directive 2008 No. 1597 Supply of Machinery (Safety)
Regulations 2008. Regulators with a CE marking and/or UKCA marking
have a declaration of conformity, which includes information about theapplied conformity assessment procedure. The declaration of conformity is
included in the 'Certificates' chapter.
− To ensure appropriate use, only use the regulator in applications where theoperating pressure and temperatures do not exceed the specifications used
for sizing the regulator at the ordering stage.
− The manufacturer does not assume any responsibility for damage caused byexternal forces or any other external factors.
− Any hazards that could be caused in the pressure regulator by the process
medium, operating pressure or by moving parts are to be prevented bytaking appropriate precautions.
− Proper transport, storage, installation, operation, and maintenance areassumed.

EB 2560 EN

Process medium and scope of application2

Process medium and scopeof application

Pressure regulators for cryogenic gases andliquids as well as other liquids, gases andvapors. Operating pressures up to 63 bar,with set points from 1 to 40 bar. Temperature
range from –200 to +200 °C. Oxygen clean
according to international standards andguidelines.
The regulators are designed to keep thepressure constant to the adjusted set point,
especially in cryogenic plants.
! WARNING
Risk of injury and property damage due tohigh pressure in the plant.
A suitable overpressure protection must be
installed on site in the plant section.

2.1 Transportation and storage
The regulators must be carefully handled,transported and stored. Protect the regulators
against adverse influences, such as dust, dirt
or moisture during storage and transportation before being installed.
In the delivered state, the pressure regulators
are packed to be free of oil and grease foroxygen service. To avoid contamination, do
not open the packaging until immediately
before installation.

Design and principle of operation

See Fig. 1 on page 7.
Ports A and B are marked on the valve body.
Type 2357-11 Pressure Build-up Regulator
Functioning as a Type 2357-11 Pressure
Build-up Regulator (Fig. 1) with direction offlow from port B to port A, the pressure upstream of the valve (port B) is transmitted tothe operating diaphragm. The valve closes
when the upstream pressure increases andopens when the upstream pressure drops.
The pressure build-up regulator operates asa safety valve and relieves the pressurechamber of pressure when the pressure
exceeds the set point by 5 bar. Afterovercoming the force of the top plug spring(16), the valve opens to equalize thepressures.
The valve is open when no pressure isapplied. The pressure upstream of the valve(port B) is transmitted to the operating
diaphragm (3). The positioning force
produced moves the valve plug (2)depending on the spring force adjustable atthe set point adjuster (10). The valve closes
when the pressure upstream of the valve(port B) increases.

6

Type 2357-11 Pressure Reducing Valve
The process medium flows from port A toport B when the Type 2357-11 Pressure Regulator is used as a pressure reducing valve.
The valve is open when no pressure isapplied. The pressure downstream of thevalve (port B) is transmitted to the operating
diaphragm (3). The positioning force
produced moves the valve plug (2.1)
depending on the spring force adjustable atthe set point adjuster (10). The valve closes
when the pressure downstream of the valve(port B) rises.
Type 2357-21 Excess Pressure Valve
The medium flows through the Type 2357-21
Excess Pressure Valve (Fig. 3) from port B toport A. The valve is closed when no pressure
is applied. The pressure at port B is transmitted internally to the operating diaphragm(3). The positioning force produced opposes
the adjustable spring force. The valve opens
when the pressure increases until the set
point is reached. The integrated non-return
unit prevents the medium from flowing back.

EC type examination
An EC type examination according to thePressure Equipment Directive 2014/68/EU,
Module B has been performed on theType 2357-11 Regulator.

Installation

Installation

In the delivered state, the regulators arepacked to be free of oil and grease for oxygen service.
! WARNING
Use of oil and grease in oxygen atmospheres!
Risk of explosion!
Make sure that the regulator is absolutely
clean and free of oil and grease on installingit.

4.1 Mounting orientation
Install the pressure regulator
with the actuator housing
suspended downward inhorizontal pipelines. Observe
the flow direction.

B

Type 2357-11 Pressure Build-up Regulator
with safety function− Direction of flow from port B to port A
Type 2357-11 Pressure Reducing Valve− Direction of flow from port A to port B

Flush and clean the pipeline thoroughly before installing the regulator.

Type 2357-21 Excess Pressure Valve with
with non-return unit

− Make sure the regulator is installed freeof stress.

− Direction of flow from port B to port A.

− Install a strainer upstream of the regulator.

Required spare parts and accessories arelisted in Data Sheet u T 2570.

Otherwise, impurities in the pipeline may
impair the proper functioning of thevalve, above all the tight shut-off.

A

The ports are marked.

4.2 Shut-off valve
We recommend installing a hand-operated
shut-off valve both upstream and downstream of the regulator. This allows the plant
to be shut down for cleaning and maintenance, and when the plant is not used for
longer periods of time.
Install a pressure gauge at a suitable point tomonitor the pressures prevailing in the plant.

Operation

See Fig. 1 on page 7.

5.1 Start-up
Do not start up the regulator until all parts
have been mounted.

5.2 Set point adjustment
Every pressure regulator is delivered with theset point listed in Table 1 already adjusted.
Turn the set point adjuster (10) using Allen
key (width across flats 5) to change the default set point.
Provided a pressure gauge has been installed at a suitable point in the plant, the required set point can be directly adjusted
while monitoring the pressure reading at thegauge.
When a pressure gauge is not installed, adjust the set point using the adjustment diagram Fig. 2.
To increase the set point, turn the set point
adjuster into the body () and out of the
body () to reduce it.
! NOTICE
Set point adjuster screwed too tight!
The regulator is blocked and the medium
flow through it is restricted. Pressure regulation is no longer possible.
Only screw the set point adjuster up to thepoint where the spring tension can still be
felt.

EB 2560 EN

How to proceed:
1. Undo the lock nut (11, width across flats17) to allow the set point adjuster tomove freely.
2. Determine the difference between the
fixed set point (Table 1) and the required
set point. Turn the set point adjuster (10)the required amount of turns as specified
in Fig. 2 on page 10.
Based on the default setting, any subsequentchange to the set point can be also be madeby determining the required number of turns
using the specifications listed in Table 1.
3. Lock the setting with the lock nut (11).

5.3 Changing the set point
range
The default set point ranges can be adapted
to your specific requirements. Contact
SAMSON (see Chapter 7) for further details.

5.4 Decommissioning
Close first the shut-off valve on the upstreamside of the valve and then on the downstream side of the valve.

50Servicing

The regulators do not require much maintenance. Nevertheless, they are subject to natural wear, particularly at the seat, plug andoperating diaphragm.
Depending on the operating conditions,check the regulator at regular intervals to
avoid possible malfunctions.
! WARNING
Process medium can escape uncontrolled
on dismantling the regulator.
Risk of cold burns!
Allow the regulator to defrost before depressurizing and draining it and remove it fromthe pipeline.
If faults or malfunctions cannot be remedied,contact SAMSON (see Chapter 7).
