Liquefied Petroleum Gas, Back-flow Safety Valve
GMK has a record of excellence in both product or service development and delivery, as well as an excellent reputation amongst clients.
A Liquefied Petroleum Gas, Back-flow Safety Valve is fitted in the liquid phase exit pipe of liquefied petroleum gas. The temperature range that this valve is designed to accommodate is from -40 to 80 degrees Celsius. When there is a pressure difference of more than 0.5 MPa between the input and output, the flow of liquefied petroleum gas will automatically reverse direction and return to the tank. Equipment or pipelines that carry LPG or other similarly non-corrosive media have an operating temperature range, and as a result, they need a safety valve.
