Pressure Sustaining Valves

Pressure sustaining valves, also known as back pressure valves (BPVs), automatically maintain a minimum upstream pressure regardless of downstream demand or fluctuations in flow. They protect pumps, reservoirs and distribution systems by ensuring adequate system pressure is maintained before allowing flow downstream.

Our range includes direct acting and pilot operated pressure sustaining valves in stainless steel and ductile iron, available with BSP threaded and flanged connections for water distribution, industrial process control and municipal pipeline applications. Adjustable pressure settings and pressure gauge options provide accurate back pressure regulation across a wide range of operating conditions.

Pressure sustaining valves are commonly installed on pump discharge lines, filtration systems and distribution networks to prevent loss of upstream pressure, improve system stability and protect critical equipment from low-pressure conditions.
