Back Pressure & Overflow Valves

Universal Back Pressure Valves for all applications

Back Pressure Valves are designed to control an adjustable and constant pressure upstream of the valve. A spring keeps the valve closed. As the inlet pressure rises the valve opens.

These self-acting overflow valves are used to maintain a constant P1 (upstream pressure) within a system.
