Non rising stainless steel gate valve, replacing traditional cast iron valve, has a compact structure, reasonable design, good valve rigidity, smooth channel, large flow coefficient, small flow resistance coefficient, simple structure, and easy maintenance. The models are Z45H-10C, Z45W-16P, and Z45W-25R. Its sealing surface is made of stainless steel and hard alloy, with a long service life. Adopting flexible graphite filler, reliable sealing, and easy and flexible operation. It refers to a valve where the closing element (gate) moves vertically along the centerline of the passage, and the gate valve is mainly used for cutting off in the pipeline. Flexible and reliable operation, excellent sealing performance.
