Valves are critical parts of hydraulic systems, where they perform several functions. Needle or plunger valves are ideal to control and regulate the flow of fluid when accuracy is a requirement. The typical design consists of a tapered plunger or needle moving into a tapered seat and driven by a handle. Typically, the grip is easily engaged by hand. As the main characteristic, this kind of valve requires many turns of the handle for even a small increase or decrease of the flow. Such gradualness ensures precision, making plunger valves perfect for those applications that entail fine flow control and precise pressure regulations.
Another important feature is excellent behavior with pressure differentials. Frequent uses include, among others, carburetors, gas piping, and water heaters. Typically, plunger valves are made of robust materials such as copper, brass, and steel. Different thread sizes and connection types are available. Usually, the thread size ranges from 1/8'' to 9/16'', while common connections include flares to the male or female pipe.
