Knife Edge Gate Valve Manuacturer

Kinfe Edge Gate Valve India


The knife edge gate valve is given a special and specific design that ensures there is least contact among the parts of the valve reducing the wear and tear due to the frequent contact. This kind of valve is used in places that work with thick fluids having a high level of viscosity. As the shape of the wedge is partly circular and rectangular, the flow changes in a non linear manner. The main difference that you find in the gate valve and the knife gate valve is that it does not have the bonnet just like the simple gate valve. It comes in both unidirectional and bidirectional flow depending on the design and the industry where it serves the application. These knife edge gate valves can be used in the locations such as mills, slurries and other industries that work with substances like ash, powder, dust, etc. There is a wide range of sizes available in the Knife Edge Gate Valve up to 36. This enables the customers to select the exact model of gate valve as per their requirements of the site and pipeline.

Square Type Knife Edge Gate Valve :

Designed for higher flow capacity and to solve any kind of leakage problems and minimal pressure drop, its internal structure avoids any types of buildup of solids. This type of gate valve is utilized in chemical plants, power plants, wastewater treatment, mining & food processing industries.

Bi-directional knife gate valve V/s Uni-directional knife gate valve :

Bi directional knife edge gate valve is seal on either side of the gate & work with back pressures, and providing sufficient water tightness while Uni directional knife edge gate valve is seal on just one side and is economic general purpose valve operated both way.
