Knife Edge Gate Valve


Knife Edge Gate Valve is one of the specific designs among other Industrial Valves. This design ensures minimum contact between the parts of the valve, Reduces the Wear & Tear. The high performance Knife Edge Gate Valve feature. Non Sliding Motion, Avoid Sliding Contact between Body & Gate allow flushing of media form the valve interior. Batten edge of the Gate (Knife-Edge) allows the tight shut off even when solid particles settles at the bottom of the Body.


A wide variety of hardened. trim options are available on Gate. Seat and Wear Ring. Knife Gate Valve are Generally, Unidirectional Valves, Excellent Hopper Isolation valve with their ability to cut through flowing media and closed by dislodging any material in the seating area. Knife-Edge Gate Valves. withstand high Temperature Abrasive Slurries in Mining, Steel, Power, Chemical, and Paper industries ideal for hign-density Slurry Lines.
