Description
Technical Specifications
The unidirectional knife Gate Valves are mainly used on industrial pipeline for on-off operation.The valve structure eliminates potential clogging shutoff when the valve is dealing with liquids that contains particles.Beveled knife gate design also generates great shear stress for easy flow penetration.Additionally, beveled knife edge helps the gate cut through thick media easily.
Designed for applications such as:
Pulp & Paper, Water Treatment，Beverage & Food，Fine Chemical,
Power Planet，Steel Industry, etc.
