Unlike other valves, gate valves are either all the way open or all the way closed. They are often used as the main control valve

The gate valves are mostly used for liquid streams. And in the same time the pumps are used to move fluids (liquids, slurries, or gases). A pump displaces a volume by physical or mechanical action.

parallel type valves with vertical sealing: two parallel, namely the centerline of the parallel seal gate valves. Parallel type gate usually adopt double disc structure.

Knife gate valves are widely used in chemical, coal, sugar, sewage, paper making, etc, it is an ideal seal gate valves.

A disk-shaped, valve, valve seat passage around the rotating shaft to rotate, due to a passage in the valve into the flow line, flow resistance score single type, double valve type and most type three

the installation of manual knife gate valve.1. Should be checked before installation and sealing surface of the valve cavity and other parts, does not allow any dirt or sand attached.

The gate valves are most significant constituent which is broadly utilized in pipes of distinct types to open and close the flow of the liquid.

Wedge type gate structure characteristics and principle1 wedge type gate valve internal medium channel is the direct, medium flows when the valve without changing its flow direction, so small flow res
