Knife Edge Gate Valve Manufacturers
Design Features
"Metflow Engineers" Knife Edge Gate Valve design ensures minimum contact between the parts of the valve,Reduces the Wear & Tear. Valve design is Non Sliding Motion,Avoid Sliding Contact between Body & Gate allow flushing of media from the valve interior. A wide variety of hardened trim options are available on Gate,Seat and Wear Ring. Batten edge of the Gate (Knife-Edge) allows the tight shut off even when solid particles settles at the bottom of the Body.
"Metflow Engineers" Knife Gate Valve are Unidirectional Valves , Excellent Hopper Isolation Valves with their ability to cut through flowing media and closed by dislodging any material in the seating area.
Knife-Edge Gate Valves are widely use in Mining,Power, Steel, Chemical, Paper and withstand high Temperature & Abrasive Slurries in Industries Ideal for high-density Slurry Lines.
