Pressure Sustaining Valves – Precision Flow Control from Solenoid Valve World
At Solenoid Valve World, we supply premium Pressure Sustaining Valves engineered to maintain constant upstream pressure in a wide range of fluid control systems. These valves are critical for stabilising system performance, protecting downstream equipment, and ensuring consistent operation under variable demand.
Whether you’re working with water, air or industrial process fluids, our pressure sustaining valves are designed for durability, reliability, and precise pressure management.
What Is a Pressure Sustaining Valve?
A pressure sustaining valve (also known as a back pressure or upstream pressure regulator) is designed to maintain a set pressure level upstream of the valve. It automatically opens or closes in response to system pressure changes, ensuring that pressure remains within desired parameters even when flow fluctuates.
