Pressure reduction controllers consist of a valve and a pressure actuator. They are used in water and steam applications.
The pressure reduction is set to absolute pressure. It is installed in the flow, before the application where pressure needs to be reduced.
The pressure reducer is required in network locations where the pressure is very high and/or varies a lot.
This typically occurs close to pumping stations in the network. Reducing high pressure enables accurate and stable temperature control of the application behind the pressure reducer.
Features and benefits
Eliminates pressure variations and provide optimum operating conditions with improved temperature control quality
Made for demanding systems, resistant to corrosion, cavitation and dirt
Connected system is protected against pressure surges, fluctuations, cavitation and noise
