Pressure Relief Valves

Pressure relief valves, also known as breather valves and vent valves, are available to prevent excessive pressure or vacuum build-up in the sealed case.

Pressure may be equalised either automatically or manually without risk of water or dust ingress, effectively blocking contaminants such as dirt and salts. A two way automatic relief valve with a push button override is offered.

Valves are available that meet SAE AS27166 and MIL- DTL-27166 (the re-instated version of MIL-V-27166) as well as IP69k, the highest protection rating available.
