The ceramic seal knife gate valve has good shear function because of its knife gate. It is most suitable for slurry, powder, fiber and other uncontrollable fluids. It is widely used in papermaking, petrochemical, mining, drainage, food and other industries. With a variety of valve seats to choose from, and according to the field control requirements, equipped with electric or pneumatic actuators, to achieve automatic valve operation.
1. Ultra-short structure length, save material, and greatly reduce the overall weight of pipeline system;
2. Small occupancy of effective space, can effectively support the strength of the pipeline, can reduce the possibility of pipeline vibration;
3. The gate is made of austenitic stainless steel, which can greatly improve the corrosion resistance and effectively prevent the seal leakage caused by the corrosion of the gate;
4. Flexible PTFE is used as the sealing filler to ensure reliable sealing and flexible operation;
5. The gate plate has the function of a knife, which can effectively break all kinds of sundries in the brake medium;
6, the use of hard sealed stainless steel, disc spray welding treatment, can expand the valve on the temperature, pressure requirements.
