【Product Usage】

Z47WF gas gate valve (non-leaking gas flat gate valve) is dedicated to natural gas, liquid petroleum gas, oil, etc., it is a unique design, novel structure and good sealing performance completely solve the valve due to gas coke caused by lax , Open fixed and other issues, effectively improve the sealing performance and service life, to achieve zero leakage.

【Product Features】

The valve body adopts casting structure.

The valve seat is sealed with O-ring seal and the floating valve seat with pre-tightening force is applied to the valve seat. The opening and closing torque of the valve is 1/2 of that of ordinary valve, so it can open and close the valve easily.

Seat with PTFE sealing on the seat, with PTFE on the metal and metal-to-metal dual seal, PTFE sealing surface at the same time remove the role of gate dirt.

Valve gate, whether full or full closure is always consistent with the sealing surface, the sealing surface is protected from direct media erosion, thereby extending the service life.

When the valve is fully open, the channel is smooth, the flow resistance coefficient is very small, no pressure loss, can pass the hair ball cleaning pipeline.

When the valve is closed automatically remove the cavity pressure (see the working principle diagram) to ensure the use of safety.

Closed gear rotation opening and closing instructions, can clearly reflect the long-term valve opening and closing situation.

Directly buried the outer surface of the valve using epoxy coal tar anticorrosive treatment, with the pipeline with the life.
