Bermad Hydraulic Pressure Sustaining Relief Valves

The BERMAD 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. A pressure sustaining valve maintains a minimum set pressure upstream of the valve, catering for fluctuations in pressure on either side of the value. The valve gradually opens or closes accordingly to maintain a set pressure. 

FEATURES & BENEFITS

• Line Pressure Driven, Hydraulically Controlled
