Safety relief valves
WITT safety relief valves protect against over pressure by venting excess gases from pipelines, gas receivers and other equipment.
The spring-loaded, direct action relief valves are suitable for individual opening pressures from 5 mbar to 45 bar (approx. 0.07 to 1 435 psi).
The compact size allows easy installation in any orientation. A dust cap protects the safety relief valves against dirt.
WITT safety relief valves are available in brass or stainless steel, as ventable version, and with or without condensation outlet.
