Product Overview
Knife gate valves are widely used in industries such as paper making, petrochemical, mining, drainage, food, and other industries due to their use of knife shaped gate plates, which have good shear effects and are most suitable for fluids that are difficult to control such as slurry, powder, and fiber. There are multiple valve seats to choose from, and electric or pneumatic actuators can be equipped according to on-site control requirements to achieve automatic valve operation.
Product Features
1. The structure of the ultra short length, save material, can make the pipeline system greatly reduce the overall weight;2. Take up the effective space is little, can effectively support the pipeline strength, can reduce the possibility of pipeline vibration;
3. Choose austenitic stainless steel gate, decay resistance performance is greatly improved, can effectively prevent because of damper sealleakage caused by corrosion
4. PTFE packing on using the flexible, reliable seal, flexible operation of the light;
5. Has the function of knife gate can effective brake circuit medium of various kinds of sundry;
6. Hard seal stainless steel material, the disc spray welding processing, can extend the valve to temperature and pressure requirements.
