Thermal release valve TAVZ 2

This VdS approved thermal release valve with double pipe priority valve is designed for the automatic thermal release of a one-way CO2 bottle with ½” UNF thread. It contains an integrated priority valve for connecting an upstream actuation element (e.g. alarm or ventilation valve).

No tool is required for tensioning the piercing needle and thermo bulb. The thermo bulbs G5-RWA-68 and G5-RWA-93 are suitable for use with this valve.

For pipe connection of the valve, four male connectors 1/8″ (e.g. B1-6-1/8) will be required additionally.

The design of the SHEVS may require reliable venting of the piping.
