There are multiple options for Rotarex Valve PRD's.
1) Y142 Pipe-Away TPRD - Triggered by excess heat AND/OR excess system pressure, the pipe-away Y142 is a vented glass bulb thermal PRD for vehicle CNG tanks. It is designed to pipe CNG away from the system and safely vent it out.
Glass Bulb thermal PRD vented pipe-away completely vents excess pressure at a preset temperature. Fast reaction time, full flow, no freezing.
Manufacturer Part #: Y14211001
2) Y142 Metal Fusible TPRD - Triggered by temperature ONLY, upon being triggered, the metal fuses and allows the gas to escape and vent out right from the PRD. These can NOT be used in a pipe-away design.
