Electric Knife Gate Valve
Product overview
Electric knife gate valve has good shear effect because of its use of 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.
Product Features
1. Ultra short structure length, saving materials, can greatly reduce the overall weight of the pipeline system;
2. It can effectively support the strength of the pipeline and reduce the possibility of pipeline vibration;
3. The use of austenitic stainless steel can greatly improve the corrosion resistance and effectively prevent the seal leakage caused by the corrosion of the ram;
4. Flexible PTFE is used as the upper sealing packing, which is reliable in sealing, light and flexible in operation;
5. The gate has the function of knife switch, which can effectively cut off all kinds of sundries in the medium;
6. The valve is made of hard sealed stainless steel and the valve clack is spray welded, which can expand the requirements of temperature and pressure for the valve.
