GATE VALVES ADVANTAGES, DISADVANTAGES AND TYPES
What is gate valve?
A gate valve is used to Shut off the Liquid Flow in a pipeline. When the Gate is opened fully it restricts the Liquid Flow. Gate Valve doesn’t require a lot of space, a very little space along the pipe is essential. A Gate Valve consists of a Valve Body, Seat, a Disc, a wheel, a spindle, a gland for operating the Valve. In Simple Words, A Gate valve is used for controlling the flow, pressure, temperature and liquid levels by fully or partially opening or closing the valve in response to signals received from the controller.
ADVANTAGES OF USING GATE VALVES:
· The Body of a Gate Valve is simple and easy to Operate.
· Gate Value is shorter in length than Globe Valve.
· Gate Valve does not Disturb the Direction of the Liquid Flow.
· Consumes Less Power and is efficient to use.
DISADVANTAGES OF USING GATE VALVE:
· Maintenance and Manufacturing of Gate Valve is difficult when Damaged and is also Costly.
· Opening and Closing of the valve is Time Consuming
5 Different Types of gate Valves:
As we know what a Gate valve is and how it is used, let us now look at some different gate valve and find out what are there uses.
· Knife gate valves
· Slab gate Valves
· Parallel gate valves
· Bellow Sealed gate valves
