Knife gate valves are a specific type of isolation valve which is typically used for media that are not hazardous such as wastewater. The bore of a knife gate valve is fully smooth, so the use of a cleaning pig for maintenance is possible. A thin stainless-steel gate is raised and lowered into the bore by a spindle or rising screw and unlike other gate valves lifts outside the valve body when raised.
Gate Valve is a valve that opens by lifting a barrier out of a path of a fluid. It is designed with a fully open or closed service. Operation of a gate valve is performed either clockwise to open or clockwise to close. The gate moves up or down on the threaded part of the stem. Gate valves should not be used for regulation or throttling of flow because exact control is not possible.
They are designed to limit or stop the movement of a liquid in a flowing stream but there is a myriad of designs and applications that depend on the specific use case. The open or closed state of the valve can be observed from the position of the gate- if it is visible above the valve body then it is open also if it is not visible then the valve is closed.
