One bi-directional sealing clip-on slurry valve Z73X, a body with the overall structure of the slurry valves, including the valve, gate, and U-shaped seal, the valve in the bottom of the chamber has a groove and fitted with elastic U type seal when the valve closes when the gate down, ram the bottom edge of the seal contact and then compress the seal into the seal groove in the valve body and gate; shift gate slurry valves open gate from the edge of the plate at the bottom of the seal, seal flat, bounce and groove to prevent the knife gate valve in the course of the medium sediment accumulation in the groove of the valve body cavity, clogging, no residue, easy to clean pipe in order to effectively improve the sealing effect of the knife gate valve to prevent leakage when the valve is closed. Longer life, easier to maintain; flange sealing face insert O-ring, no need to reprovision the flange gasket, easy to install, the friction coefficient is small and flexible, open and close the series of knife gate valves can be equipped with a manual, electric, pneumatic electric hydraulic, hydraulic, bevel gear, and many other actuators to meet the different mining requires the use of 
 The integrated two-way sealing characteristics folder slurry valves Z73X products: 
 1 clip-in-one structure, small size, light weight; the main valve body O-ring, gate, stem, such as a stent components. 
 (2) the fully open channel, can prevent the deposition of the media in the valve; 
 3 replaceable seal structure, changed the ordinary slurry valves and knife gate valve maintenance difficult problem; 
 (4) Body material from the traditional cast steel replacement became ductile iron, corrosion resistance, better, effectively extend the service life;
