Knife gate valve

© Knife gate valve

Knife gate valve is a kind of gate valve which is shut off valve directly. Its gate head is design with bevel cutting edge, which has a cutting action to medium. Knife gate valves are suitable for those mediums contained fibers and solid particles, and sewage treatment systems. Operated by manual, pneumatic or electric actuators, knife gate valves are widely used in the process of automatic control systems in paper making, mining, chemical and sewage treatment industries.

© Product features 1. lntegral body design, small flow resistanee, smooth operation.2. Stem drive is designed with 2 plane bearings, the driving frietion is greatly redueed so making operation ofvalve beeomes smooth and light.3. Seal with moveable sealing design and 0-ring ean provide a preloading foree to push the seat sealing ringtouehing tightly with gate whieh ean provide a seif eompensation to the sealing surfaee when it had been wornafter long time in serviee, so its serviee life ean be inereased.4. Fixed guide elaw, without groove design, so medium is not easy to be aeeumulated and bloeked.5. Material of seat is seleeted aeeording to the medium and serviee eondition, ehoosing metal seal or soft seal.Metal seal with gate surfaee is eoated with hard ehromium, or Nitriding treatment, to inerease its wear resistanee.Soft seal will be with PTFE seat, or EPDM, NBR, which have good sealing performance and excellent corrosionresistance.6. With excellent sealing performance and economical practicality, and its operation can be by manual, pneumatic or electric actuator, so its application is very wide.
