1.Introduction of Water Main Gate Valve

A water main gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A water main gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve. The seat and the gate together perform the function of shutting off the flow of fluid. 

Water main gate valve is generally not suitable for regulating flow or pressure or operating in a partially open condition. For this service, a plug valve or a control valve should be used. It must be noted that because of the type of construction a water main gate valve requires many turns of the hand wheel to completely open or close the valve. When fully opened, water main gate valve offer little resistance to flow and its equivalent length to diameter ratio (L/D) is approximately 8. 
 

The gate valves used in the mainlines carrying oil or gas must be of full bore or through conduit design to enable smooth passage of scrapers or pigs used for cleaning or monitoring pipelines. Such water main gate valve is referred to as full bore or through conduit gate valves.
