Z643/943 Series Wedge Gate Valve

Z643/943 series electric/pneumatic wedge gate valve, fluid resistance small, sealing surface impact erosion is small, the flow direction of medium does not change, not disturbed flow, small pressure drop, open-close torque is small, shorter structure, process performance is good, suitable pressure and temperature range is wide, at the same time, it has since the structure characteristics of tight sealing medium pressure, can easily realize industrial pipeline medium tight shut off and on.
