Pressure reduction controllers

Product store

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

FAQ

Can I limit a max flow with a differential pressure regulator?

Yes you can. Open the control valve fully and set the max flow by adjusting the differential pressure. You can also calculate the appropriate differential pressure, but you need to know the exact capacity of the control valve.

We design an installation and need lengths of valves from a project specification.

We produce valves with a standard length. You can also find the measures in our datasheet or download 2D and 3D CAD drawing models from our product presentations. Please go to our product catalog where you will find links to documentation and drawings - follow the below link.
