UNIDIRECTIONAL KNIFE GATE VALVES
One-way unidirectional knife gate valves are designed to block or allow the flow of a media in a piping system. They have a knife-edge blade that is positioned perpendicular to the direction of flow and can be raised or lowered to control the flow of the media. The unidirectional knife gate valve allows flow in only one direction and is used in systems where flow reversal is not desired or permitted. It is commonly used in wastewater, sewage, sludge, abrasive or corrosive fluid and other viscous media applications. One-way knife gate valves can be manufactured from different materials and sizes depending on the media and operating conditions.
