  • Unidirectional sealing knife gate valve has simple and compact structure, reasonable design, lightweight materials, sealing is reliable, flexible and convenient operation, small volume, smooth channel, small flow resistance, light weight, easy to install, easy to remove, etc, thoroughly solved the common gate valve, flat gate valve, globe valve, regulating valve, butterfly valve, ball valve, such as the weight of the common valve, flow resistance, the area is large, difficult problems, such as installation,it can replace the general cut-off valve and regulating valve, and can work normally under the working pressure of 1.0mpa-2.5mpa and the operating temperature of -29-550℃.

  • Bidirectional sealing knife gate valve is also known as non-groove knife gate valve,cast steel and stainless steel body structure of 2 style knife gate valve, including body, disc and u type sealing strip, at the bottom of the left and right sides of the valve body and lumen with grooves, and is equipped with elastic u-shaped seal when the valve is closed ram down, contact with the sealing strip and sealing strip compression at the bottom of the disc into the groove of the valve body and disc in the seal;ram up when knife gate valve open, at the bottom of the disc edge away from the sealing strip, sealing strip of pop and grooves flat valve body with blade design can prevent the knife gate valve in use process, medium sediment accumulation in the grooves in the body of the lumen, difficult to jam, no residue, pipeline cleaning is convenient, thus effectively improve the sealing effect of knife gate valve, prevent leakage when the valve is closed. non-fluted design prevents fluid retention in the valve cavity

  • The valve body of rising stem knife gate valve adopts integrated structure, prevent leakage of valve body, sealing gasket aging and a series of problems, longer service life, simpler maintenance;uses the seal at the bottom of the valve body, valve cavity without grooves, difficult to jam, no residue, pipeline cleaning is convenient, the flange sealing surface with o-rings, do not need to match flange gasket, simple and convenient installation, small friction coefficient, opening and closing flexible, the series knife gate valve can be with manual, electric, pneumatic, electric hydraulic, hydraulic, bevel gear drive, and many other actuators, in order to meet the different requirements of industrial use.

  • non rising stem knife gate valve has the advantages of simple and compact structure, reasonable design, light weight, material saving, reliable sealing, light and flexible operation, small volume, smooth passage, small flow resistance, light weight, convenient installation and disassembly, etc.Gate valves can operate at operating pressures from 1.0 mpa to 2.5 mpa and temperatures from -29 mpa to 650 mpa.Knife gate valve disc with shear function, can scrape off the seal surface adhesion, automatic removal of debris.Stainless steel gates prevent leakage of seals caused by corrosion.
