Pressure Sustaining Valves

Pressure Sustaining valves are designed to maintain a steady preset upstream pressure regardless of downstream pressure changes due to downstream demand with the preset upstream or back pressure displayed by the pressure gauge. Pressure sustaining valves automatically maintain and hold back the preset minimum upstream pressure to protect the upstream process systems from dangerously low pressures at all times. Each pressure sustaining back pressure valve can be chosen according to pressure range, size and material of construction to suit just about any media application with custom pressure ranges and port sizes up to DN500.
