Knife Gate Valve Product Usage
Knife gate valve with knife type damper, has good shearing action, the most suitable for pulp, powder material, such as fiber is difficult to control the fluid flow, widely used in papermaking, petrochemical, mining, drainage, food and other industries. With multiple seats to choose from, and can be on the basis of field control requirements, equipped with electric or pneumatic actuators, realize the automation of valve operation.
Knife Gate Valve Product Features
1.The structure of the ultra short lengh, save material, can make the pipeline system greatly reduce the overall weight;
2.Tack 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 seal leakage 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.
