Check & Non Return Valves
THERMOMAT FLASHBACK ARRESTOR
The THERMOMAT is a multifunctional safety device for use in oxy-fuel technique. It is fitted with the following safety elements:
- The flashback arrestor, as main constituent of this safety device, consists of sintered stainless steel with an accurately defined porosity which ensures an unrestricted through-flow at normal operation. Running-in flashbacks are kept back absolutely reliable due to sintered metal. The flame goes off immediately.
- The non-return valve avoids a gas reverse flow of the discharged gas and prevents any build-up of potentially explosive gas mixtures at the inlet side.
- The thermal cut-off valve cuts off gas supply in an irreversible manner in case the device warms up to an undue high temperature, e. g. if a burnback on the surface of the flashback arrestor occurs.
- Located on the inlet side of the device’s flammable gas version, a dust filter protects the non-return valve from infiltration of impurities, e. g. due to levitating tiny particles in the gas.
