1. Lug water knife gate valve:DN50-DN600

Pressure rating:DIN PN10,PN16,ANSI 150

2. Wafer thtough conduit knife gate valve:DN50-DN600

Pressure rating:DIN PN10,PN16,ANSI 150




1. Integral body design,small flow resistance,smooth operation.

2. Stem drive is designed with 2plane bearings,the driving friction is greatly reduced so making operation of valve become smooth and light.

3. Seat with moveable sealing design and O-ring can provide a preloading force to push the seat sealing ring touching tightly with gate which can probide a self compensation to the sealing surface when it had been worn after long time in service,so its service life can be increased.

4. Fixed guide claw,without groove design,so medium is not easy to be accumulated and blocked.

5. Material of seat is selected according to the medium and service condition,choosing metal seal or soft seal.Metal seal with gate surface is coated with hard chtomium,or Nitriding treatment,to increase its wear resistance.Soft seal will be with PTFE seat,or EPDM,NBR,which have good sealing performance and excellent corrosin resistance.

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.
