MODEL 1420

Pilot Operated Relief Valve w/ Vacuum Breaker

The Groth 1400 Series Pilot-Operated Relief Valves replace weight-loaded or spring-loaded valves to improve efficiency and reduce evaporation losses. They allow process pressures to operate closer to set pressure safely compared to traditional valves. This results in minimal product loss and increased profitability.

Only the pilot needs to be set

Lower profile and weight than spring operated models for high settings

Remote pilot sensing option allows the pilot to sense the true system pressure

Remote or manual blowdown available

Main valve remains tight to set pressure

Full open at 10% overpressure

Modulating action conserves product

Soft seating creates tight seal to conserve product and minimize valve wear

Top entry allows valve to be services without removal from mounting
