GDR Type 132 gas pressure regulator – up to 25 bar, DN 50–500
Constant outlet pressure even when the inlet pressure and flow rate change.
Constant outlet pressure
Maintains a constant outlet pressure even when the inlet pressure or flow rate changes.
Type 132 gas pressure regulator: constant outlet pressure under varying conditions
The GDR Type 132 gas pressure regulator is designed to maintain a constant outlet pressure – regardless of changes in inlet pressure and/or flow rate.
The Type 132 is intended for gases in accordance with DVGW Worksheet G260 and for non-corrosive gases. Special versions are available for corrosive gases, in particular landfill or sewage treatment plant gases.
The maximum inlet pressure is 25 bar, and the maximum outlet pressure is 16 bar. The standard minimum pressure differential is 100 mbar. With an enlarged diaphragm housing, 20 mbar is specified, and 3 mbar for a pressure-controlled version.

Technical specifications of the Type 132 gas pressure regulator
An overview of the key technical specifications of the Type 132 gas pressure regulator – from pressure ranges and nominal diameters to the control range, operating temperature and connection types.
Design and operation of the Type 132 gas pressure regulator
Control regulator, pressure reducer and actuator
The Type 132 gas pressure regulator consists of the control regulator, pressure reducer and actuator assemblies. The control regulator is available in DN and DH versions: the DN type is used as standard for operating pressures up to 50 mbar, whilst the DH type is used for ranges above 50 mbar. Where the pressure difference between the inlet and outlet exceeds 1.5 bar, the SR pressure reducer is used.
How the Type 132 GDR works
The inlet pressure first reaches the ball valve and the balancing diaphragm. It is then routed via the control pressure line to the pressure reducer and subsequently to the control regulator. The pressure reducer limits the control pressure and is fitted with an integrated fine filter.
Via the control regulator, the control pressure enters the diaphragm chamber and acts on the working diaphragm. This rises and opens the cone valve. The resulting back pressure is returned to the control regulator via the impulse line. As soon as the set pressure is reached, the control valve closes. Via the control nozzle and the outlet line, the control pressure equalises with the back pressure and the cone valve closes again. The Type 132 gas pressure regulator is thus in the regulated state.
