Flanged stainless steel pressure sustaining valve.

Flanged Pressure Sustaining Valve


  • Our pressure sustaining valves maintain a minimum set pressure upstream of the valve, catering for fluctuations in pressure on either side of the valve.
  • This is achieved by the valve gradually opening or closing to maintain a set pressure.
