Z47WF gas gate valve
Gas gate valve is a type of gate valve mainly used in gas, petroleum, natural gas, and other media.
The Z47WF gas gate valve (leak free gas flat gate valve) is specifically designed for natural gas, liquid petroleum gas, oil products, etc. With its unique design, novel structure, and good sealing performance, it completely solves the problems of valve closing and opening caused by gas coking, effectively improving sealing performance and service life, truly achieving zero leakage.

Product Features
The valve body adopts a casting structure. The valve seat adopts an O-ring seal and a floating valve seat structure with pre tightening force applied, making the inlet and outlet of the valve sealed in both directions; And the opening and closing torque of this structure is only half of that of ordinary valves, which can easily open and close the valve. The valve seat adopts PTFE embedded on the sealing surface, which has a dual sealing effect of PTFE to metal and metal to metal. The PTFE sealing surface also removes dirt from the gate plate. The gate of the valve, whether fully open or fully closed, always matches the sealing surface, and the sealing surface is protected from direct erosion by the medium, thereby extending its service life. When the valve is fully open, the channel is smooth and straight, the flow resistance coefficient is extremely small, and there is no pressure loss. It can clean the pipeline through a ball. When the valve is closed, it can automatically remove the high pressure in the inner chamber (see the working principle diagram for details), ensuring safe use. Adopting a closed gear rotation opening and closing indicator mechanism, it can clearly reflect the opening and closing status of the valve for a long time. The outer surface of the directly buried valve is treated with epoxy coal asphalt anti-corrosion treatment, which can have the same lifespan as the pipelinea
