Integrated two-way sealing wafer type knife gate valve Z73X is a body with the overall structure of the slurry valves, including valve, gate, and U-shaped seal, the valve in the bottom of the chamber has grooves and fitted with elastic U-shaped seal when the valve closes when the ram down, ram the bottom edge of the seal contact and then compress the seal into the groove of the valve body and gate seal; shift gate slurry valves open. out of the gate at the bottom of the edge of the seal, seal flat, bounce and groove to prevent the knife gate valve in the course of the media sediments accumulated in the groove of the valve body cavity, easy to plug, no residue, pipe cleaning convenient, in order to effectively improve the sealing effect of the knife gate 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 
 One two-way sealed folder knife gate Z73X product characteristics: 
 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; 

 Strong Germany, and select safe!
