304 Flanged Control and High Temperature Precision Needle Valve stock at best price

Needle Valves allow for precise control of liquids. These are used in automobile fuel injection systems, industrial machineries, power plants and other highly sensitive applications where the flow of fluid has to be regulated precisely. The Needle Flow Control Valves have a gearbox, a needle and a shaft where the needle sits in. The shaft is moved up and down the gearbox allowing the needle to come to open and close positions. As the needle moves in and out very precisely, and the volume is controlled by the needle blocking the passage, the control is also very precise. The applications include flow control, pressure regulation, pump start, turbine by pass, discharge, reservoir inlets and in air regulations mechanics.

What is a needle valve?

The valves are produced based on the need of the applications. The Small Brass Needle Valves are available for smaller application requirements such as fuel injection systems which use miniature sized needle valves. The pressure capacities of needle valves are higher than the other types of valves because of the smaller size of the input and output along with packed body types.
