Pressure Sustaining Valves

A pressure sustaining valve maintains a minimum set pressure upstream of the valve, catering for fluctuations in pressure on either side of the value. This is achieved by the valve gradually opening or closing to maintain a set pressure. See Bermad’s range of pressure sustaining valves below.
