Air Operated Pressure Relief Valve (pipe-away design)

The Groth Model 1560 Air Operated Pressure Relief Valve with pipe-away design is used to replace weight-loaded, spring-loaded, and pilot-operated valves in severe applications where polymerization and crystallization may take place and plug as well as corrode the control orifices. The air-operated valve increases valve efficiency and reduces evaporation losses. The pressure switch coupled with a solenoid valve and using plant instrument air instead of corrosive product vapor provides a bubble tight seal in the valve. Additionally, the use of clean air greatly reduces maintenance time when compared with the pilot-operated valve. By using the air-operated valve, remote sensing is provided by the pressure switch. This valve provides greater conservation due to minimum product loss which in turn adds to the profits at the bottom line.
