- Main Voltage: 120 V AC, 50/60 Hz (Q)
The tightness control TC checks the fail-safe function of both valves before each start-up or after each shut-down of a system with two safety valves.
The aim is to identify an inadmissible leak on one of the gas valves and to prevent burner start. The other gas valve continues working properly and takes over the safe shut-off of the gas supply.
- Adjustable test period which can be adapted to different systems
- Adjustable test instant allows quick system start
- Maximum safety thanks to self-monitoring electronics
