Z641/941H Series Flat Gate Valve

Electric Flat Gate Valve flow resistance small, can realize automatic positioning on sealing surface, flat gate valve is a kind of closed for the parallel slide valve of the gate, gate to the seat of the clamping force is the action and the floating gate or floating seat of medium pressure to control, especially suitable for medium with suspended particles of reliable on-off control.

Product Description

Electric Flat Gate Valve

A electric flat gate valve is a type of industrial valve used to control the flow of fluids, such as liquids or gases, within pipelines. It is named "flat" due to the flat or parallel gate that moves vertically to open and close the valve. 


Electric flat gate valve has the advantages of small size, small flow resistance, light weight, easy installation, easy disassembly, etc. It completely solves the problems of large flow resistance and heavy weight of ordinary gate valves, flat gate valves, ball valves. It has the advantages of small size, small flow resistance, light weight, easy installation, easy disassembly and so on. Installation difficulties, large floor space and other problems. After the appearance of knife gate valve, a large number of replace the general globe valve and regulating valve.

Knife gate valve installation space is small, low working pressure, not easy to accumulate debris, lower price.

When the knife gate valve is closed, the sealing surface can only rely on medium pressure to seal, that is, rely on medium pressure to press the sealing surface of the gate to the other side of the valve seat to ensure that the valve is sealed. Sealing surface. This is self-sealing. Most gate valves use forced sealing, i.e., when the valve is closed, the gate must be forced to the seat by external force to ensure the sealing surface. Such valves should normally be installed vertically in the pipeline.
