A variety of valves are used in the piping and machinery systems of the ship as per the need of the flow pattern of the liquid. All valves used on ships have the basic functionality of regulating the flow of the liquid in the pipes.

Valves are used for almost all machinery systems on ships for controlling and regulating fluid through pipes. Although valves are known as efficiency decreasing device as they reduce the energy in the liquid flow, their use is imperative in applications where limited flow is required.

Therefore, for any aspiring or serving marine engineer, it is extremely necessary to know about construction and working of various types of valves used on ships.
