What Does Gate Valve Mean?
A gate valve has a flat closure element that slides into the flow stream to stop the fluid.They are one of the most commonly used valves, and are primarily used to permit or prevent the flow of liquids.
Gate valves can be used in demanding environments such as high-temperature and high-pressure environments. They are often used in：
Power plants
Water treatment
Mining
Offshore applications
Gate valves are also known as knife valves, slide valves, sluice valves or linear motion valves
What is the function of gate valves on ships?
Gate valves are used in applications where a full unrestricted flow of the fluid is desired.As the gate can be opened to the full bore it provides very less frictional loss.
Gate valves are not suited for regulating flow as the gate arrangement allows the valve to remain in either fully closed or open position Gate valves are not suited for regulating flow as the gate arrangement allows the valve to remain in either fully closed or open position In order to increase tightness of the seal some gate valves are provided with twindiscs which can be pressed against the seat with the help of a spring when closed in case the valve requires a change in direction, a full bore angle valve can be used.
in case the valve requires a change in direction, a full bore angle valve can be Since steam causes heating and deformation of the material that it passes through;nomaly such valves do nothave a soid gate, ather they have a tlexible gate made out of two circular pltes with a hub in-etween to account tor any change ofdimensions n the vaive body.
