Fluid medium: Water,Steam
Actuator selection: Electric, Pneumatic

Model Category



Application
1)The pressure reducing station is a fully-mounted.The pressure reducer here is a directly controlled proportional controller without auxiliary power for reducing a higher input pressure to a lower minimum pressure.
2)The pressure reducer used here is solely for reducing pressure, which is why stop valves are installed for the connection of the minimum pressure side over a longer period. To guatatee a longer service life for the station a strainer and optionally, a steam drier, are provided on the input pressure side. The minimum pressure side is fitted with a safety valve adjusted to the station.
3)The input and minimum pressure are read off directly at the pressure gauge supplied.
4)A desired by pass pipe guaratees emergency operations even without a pressure reducer.
