How to connect Teco R4 Valve with Emiflex Emiteg AR Hose:
Hose insertion is QUICK and SAFE. The hose can only be disconnected when the valve is closed.
Turning the hose handle by 15° calmps it to the valve. In this position, the valve remains closed.
Turning the hose handle further opens the gas flow. The hose cannot be disconnected with the valve open.
Thermal Safety Appliance
FIREBAG® consists of an external body and an internal device thermosensitive. Upon reaching the outside temperature of 95°C - 100°C the metal alloy, that holds the shutter of the cartridge, melts and the compression force of the spring projects the shutter against the hole of passage of the gas by closing it completely.
• Thermal resistance FIREBAG® HTB GT5 925°C x60’
• Operating temperature FIREBAG® 100°C - 5K
