P4000A Fire Protection Pressure Relief Valve

Technical Data | Related Products

Manufactured by: Zurn Wilkins
Model: P4000A

The Zurn Wilkins P4000A Thermal Expansion Relief Valve will relieve excesses pressure in Fire Protection Systems, protecting fire distribution networks from high pressure build-up.

The P4000A is an adjustable direct acting pressure relief valve which senses upstream pressure. The valve will open when the upstream pressure rises above the valve’s set pressure.

Once the upstream pressure descends below the set pressure, the P4000A will close drip tight within close limits. The valve is designed for use in systems where thermal expansion, pumps or elevated plumbing could cause destructive pressure rise.
