Our Products
We offer the best product range of Pneumatic Knife Edge Gate Valve, Pneumatic Cylinder Knife Edge Gate Valve and Motorized Knife Gate Valve.
SN ENGINEERS Knife gate valves are linear shut off valves that are light weight with compact construction. Valves are available as manual with handwheel, or can be automated with pneumatic cylinder actuator for remote operation. The arc shape of the gate of our knife gate valve is designed to be particularly suitable for cutting off fluid containing fiber or suspended particles, so the knife gate valves are ideal for many applications in the process industries of Pulp & Paper, Wastewater Treatment, Mining, Sugar Mills, and Chemical Processing.
SN ENGINEERS is a prominent Knife Edge Gate Valve Manufacturer, Supplier, and Exporter in India. We have a highly experienced team of engineers, who always work to build easy to use, safe, and quickly operated valves.
We generally confirm to MSS SP 81 to follow manufacturing standards, we use IS 210 Gr. FG200 S.Steel 304 material for Valve Body, AISI 304 SS material for Trims, and CF8 / CF8M / CF3M material for Bonnet.
This valve has Metal to Metal / NBR seals, the available size range is 2” to 24” and Max. C.W.P. is 100 PSIG (7 Kg/cm2). It comes up with Lug Type Suitable For BS 10 Table “D” / ANSI B 16.1 (125#) End connections with Class IV to V Leakage Class.
For pneumatic cylinders we use Aluminium / S.Steel to make Barrel, Aluminium Pressure Die Cast / C.I. to make End cover, Stainless Steel for Piston Rod, and for Seals, we use Nitrile and also Viton on Request.
A Motorized Knife Gate Valve is a heavy-duty, industrial isolation valve designed to cut through and control the flow of thick, viscous, abrasive, or slurry-type media. The valve features a sharp stainless-steel gate that moves linearly to open or close the flow path, ensuring excellent shutoff even in challenging process conditions. The valve is operated by an electric actuator, providing automated control for remote operation, precise positioning, and reliable performance in continuous process systems.
Designed with a full round port and minimal pressure drop, motorized knife gate valves are ideal for handling pulp & paper stock, wastewater, mining slurry, ash handling, powder media, chemicals, and food processing materials. They are available in unidirectional and bidirectional designs, with body materials such as Cast Iron, Ductile Iron, Carbon Steel, and Stainless Steel, suitable for a wide range of industrial applications.
