Description

Pressure Sustaining Valve Double Chamber IR-130-DC-XZ

The BERMAD Double Chambered Pressure Sustaining Valve is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting. The double chamber feature ensures extremely fast operation to keep back pressure in the filter system , pumping station or in field valve.
