Intended use
The SAMSON Type44-0B Regulator is suitable for pressure control of vapors and the
Type44-1B Regulator is suitable for pressure control of liquids and gases.
The regulators are designed to operate under exactly dened conditions (e.g. operating pres-
sure, process medium, temperature). Therefore, operators must ensure that the regulators are
only used in operating conditions that meet the specications used for sizing the devices at
the ordering stage. In case operators intend to use the regulators in other applications or
conditions than specied, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
ÎRefer to the technical data and nameplate for limits and elds of application as well as
possible uses.
Reasonably foreseeable misuse
The regulators are not suitable for the following applications:
−Use outside the limits dened during sizing and by the technical data
−Use outside the limits dened by the additional ttings mounted on the regulator
Furthermore, the following activities do not comply with the intended use:
−Use of non-original spare parts
−Performing service and repair work not described
Qualications of operating personnel
The regulator must be mounted, started up, serviced and repaired by fully trained and quali-
ed personnel only; the accepted industry codes and practices must be observed. According
to these mounting and operating instructions, trained personnel refers to individuals who are
able to judge the work they are assigned to and recognize possible hazards due to their spe-
cialized training, their knowledge and experience as well as their knowledge of the applica-
ble standards.
Safety features
The Type44-0B and Type44-1B Regulators do not have any special safety features. When
relieved of pressure, the regulators are opened by the force of the set point springs.

Safety instructions and measures
Personal protective equipment
We recommend checking the hazards posed by the process medium being used (e.g.
uGESTIS (CLP) hazardous substances database). Depending on the process medium and/
or the activity, the protective equipment required includes:
ÎProtective clothing, safety gloves and eye protection in applications with hot, cold and/or
corrosive media
ÎWear hearing protection when working near the valve
ÎCheck with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions, conversions or other modications of the product are not authorized by SAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example. Fur-
thermore, the product may no longer meet the requirements for its intended use.
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
prevent hazards that could be caused in the regulator by the process medium, the operating
pressure or by moving parts by taking appropriate precautions. Plant operators and operat-
ing personnel must observe all hazard statements, warning and caution notes in these
mounting and operating instructions.
Hazards resulting from the special working conditions at the installation site of the regulator
must be identied in a risk assessment and prevented through the corresponding safety in-
structions drawn up by the operator.
We also recommend checking the hazards posed by the process medium being used (e.g.
uGESTIS (CLP) hazardous substances database).
ÎObserve safety measures for handling the device as well as re prevention and explosion
protection measures.
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations. Opera-
tors are obliged to provide these mounting and operating instructions as well as the refer-
enced documents to the operating personnel and to instruct them in proper operation. Fur-
thermore, operators must ensure that operating personnel or third parties are not exposed to
any danger.

EB 2626-1 EN 1-3
Safety instructions and measures
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
well as the referenced documents and observe the specied hazard statements, warnings
and caution notes. Furthermore, operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.
Referenced standards, directives 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 'Certicates' section.
According to the ignition risk assessment performed in accordance with Clause5.2 of
ISO80079-36, 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.
ÎFor connection to the equipotential bonding system, observe the requirements specied in
Clause6.4 of EN60079-14 (VDE0165-1).

ation
ÎSee Fig.3-1
The Type44-0B and Type44-1B Pressure
Reducing Valves consist of a single-seated
globe valve with integrated actuator unit.
The regulators mainly consist of the valve (1)
with seat (3), plug (2) and balancing bellows
(6) as well as a spring housing with operat-
ing bellows (5), set point spring (7) and set
point adjuster (8)/set point screw (9).
The pressure reducing valves are used to
maintain the pressure downstream of the
valve to an adjusted set point.
The regulator is open when relieved of pres-
sure. It closes when the downstream pressure
rises above the adjusted set point. The pro-
cess medium ows through the valve be-
tween seat and plug in the direction indicat-
ed by the arrow on the body. The position of
the valve plug determines the ow rate and,
as a result, the downstream pressure.
The downstream pressure p2 to be controlled
is transmitted through a borehole (4) in the
valve body to the operating bellows (5)
where it is converted into a positioning force.
This force is used to move the valve plug ac-
cording to the force of the set point spring
(7). The spring force is adjustable at the set
point adjuster (8/9).

Design and principle of operation
3.1 Additional ttings
ÎSee Fig.3-2
Strainers
We recommend installing a SAMSON
strainer (3) upstream of the valve. It prevents
solid particles in the process medium from
damaging the regulator.
ÎDo not use the strainer to permanently
lter the process medium.
ÎSelect a strainer (mesh size) suitable for
the process medium.
Any impurities carried along by the process
medium may impair the proper functioning
of the regulator. We recommend installing a
strainer (e.g. SAMSON Type1NI) upstream
of the pressure reducing valve (uEB1010).
Pressure gauges
Install a pressure gauge (2 and 4) both up-
stream and downstream of the regulator to
monitor the pressures prevailing in the plant.

Bypass and shut-off valves
We recommend installing a shut-off valve (1)
both upstream of the strainer and down-
stream of the regulator and installing a by-
pass line. The bypass ensures that the plant
does not need to be shut down for service
and repair work on the regulator.
Insulation
Regulators can be insulated to reduce heat
energy transfer.
Refer to the instructions in the 'Installation'
section.
The Types44-0B and 44-1B Regulators are
not safety valves. If necessary, a suitable
overpressure protection must be installed on
site in the plant section.
