Needle Valves are valves designed for flow control and regulation applications. Some shut-off valves such as Butterfly Valve, Gate Valve are also used for adjustment purposes, but these valves are unsuitable for continuous adjustment. The working life of Gate Valves and Butterfly Valves used continuously at high pressure differences and for adjustment purposes will be shortened and damage will occur quickly. Another feature of regulating valves is the control characteristic.
At the inlet of the Needle Valve, the flow is diverted to the internal structure of the body, which narrows smoothly in the ring cross-section and from the inlet to the outlet. The ring cross-section of Needle Valves is maintained throughout the entire closing movement of the piston, which makes Needle Valves ideal control valves. The axial movement of the plunger controls the outlet port of the valve in a linear characteristic.
