87 PSI High Pressure Dump Valve Assembly

An ultra-high-pressure valve designed to rapidly depressurize the Essential Pump’s high-pressure water circuit during shutdown, commanded pressure release, and system servicing. By providing a controlled path for trapped high-pressure water to discharge from the system, the valve supports safe pump operation and helps protect intensifier, attenuator, and high-pressure plumbing components from retained pressure.

Service tip: Replace the complete assembly when internal wear, leakage, delayed pressure release, or unreliable valve cycling can no longer be corrected through routine valve maintenance. Fully depressurize and lock out the pump before servicing any dump-valve or high-pressure component.
