Description

The Groth Model 1660A Pilot-Operated Relief Valve with Pipe-Away feature is used on liquid storage tanks and other process vessels or systems to prevent structural damage due to excess internal pressure or vacuum. The pilot-operated relief valve has two principal advantages over standard types of relief valves: 1) it is bubble tight to set pressure, and 2) it is fully open at less than 10% above set pressure. These characteristics permit an operating pressure nearer to the maximum allowable working pressure of the tank. High operating pressures reduce evaporation and total venting volume, thereby reducing product loss and cost of processing emissions.
