English term or phrase:internal reverse flow check valve
Most of VICTOR welding torch handles are equipped with patented internal check valves. This reduces the possibility of explosion or fire which may occur as a result of fuel gases and oxygen becoming mixed inside the hoses or regulators. VICTOR strongly recommends installing accessory reverse flow check valves to any torch not equipped with internal check valves.
The purpose of an internal check valve is to reduce the possibility of reverse flow gas.
