Oxeo Pilot Line Pressure Relief Devices and Fittings
The Oxeo pilot line pressure relief devices are used in accordance with the project specific system schema in fixed fire extinguishing systems. The safety device malfunction pressure relief assemblies (part numbers 24498 and 24499) release small amounts of leakage from pneumatic pilot lines and close automatically when subjected to higher pressures. The devices are intended only for releasing small amounts of pressure. Installation of the devices near any sources of potential leakage (e.g. a pilot gas tank) is recommended. The manual selector valve assembly (24499) includes an optional release device that is used to manually vent pilot lines.
