Designed for regulating fluids in process, power generation and instrumentation applications. Restrict or allow the fluid flow by using a slender needle-shaped plunger which fits in a conical seat
Parker needle valves permit precise regulation of flow, usually gas or water, through an appliance or system. These valves feature a small port and threaded, needle-shaped plunger, allowing a minimal amount of substance to pass through the valve.

Parker 338 Series needle valves provide precise & efficient flow control & adjustment for factory automation applications. They have a fine taper needle plunger that ensures accurate flow control even at low flow rates and an adjustment knob with numerical micrometre position markings for providing a clear visual indication of flow control settings. Their set screw can be tightened to consistently maintain the settings at a desired point after flow rate selection. They have heavy duty brass construction for withstanding high pressures while minimising wear & tear.

BThe needle valve utilises brass, stainless steel or plastic material for use in different applications. These materials offer chemical / corrosion resistance and can withstand high temperatures (except for plastic).
Yes, needle valves can change the fluid pressure within a system.
Throttle (needle) valves control the speed of a pneumatic device and adjust the flow rate when the air / liquid is flowing.
