Customized Pressure Reducers

STÖHR ARMATUREN develops and manufactures pressure reducers to customer´s individual specs.
STÖHR ARMATUREN also provides special services like customer design approval, radiation resistance or earthquake safety certificates, and conducts project specific approval-tests on request..




Pressure Reducer Projects – Examples:

1. Midget Pressure Reducers
Inlet pressure 5 – 20 bar.
Outlet pressure 300 mbar constant.
Exemplary for low-pressure gas storages in mobile fuel-cell systems.

2. Low-pressure Pressure Reducers
Variable inlet pressure from e.g. 5 – 10 bar.
Outlet pressure constant up to 1 bar.
Exemplary for gradual reduction of Nitrogen supply for fast reacting fire-extinguishing equipment in nuclear power plants or similar applications.

3. High-pressure Pressure Reducers
Variable inlet pressure up to 200 bar.
Outlet pressure adjustable from e.g.10 – 5 bar.
Exemplary for gradual reduction of high pressure Nitrogen supply for fast reacting fire-extinguishing equipment in nuclear power plants.

4. Absolute-pressure Safety Valve
Inlet pressure 2 bar.
Outlet pressure 80 mbar gauge pressure (depending on ambient conditions).
Exemplary for air transport of cryogenic dewars or satellites.
