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.
Bi Directional Flow Control Valves
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.

Features
- These valves are designed for safe isolation and controlling the flow to pressure metering devices, such as gauges, transmitters or switches.
- They feature a self-centring, non-rotating stem tip for a bubble-tight shutoff and anti-blowout low torque.
- They come integrated with a gland lock nut that maintains a secure connection with limited vibrations.
- They are ideal for skids, water treatment, chemical injection skids, gas booster systems, pressure & flow measurement and test equipment.
- Models, such as MV-13 Series needle valves, utilise a high purity PFA body that makes them ideal for aggressive chemical and gas applications. They also come with stem sealing for a smooth and consistent flow.
Working Mechanism
- The needle valve's plunger has a tapered end that raises or lowers with the spin of a T-handle to open / close an orifice.
- The handle is connected to the plunger with the help of a stem. A locking nut is provided to prevent the plunger from fully unscrewing when the handle is turned.
- As the plunger moves down, the pointed end comes into contact with the valve seat to fully seal the orifice and allows for accurate flow rate control.
Frequently Asked Questions
What are these needle valves made of?
The 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).
Does a needle valve change the fluid pressure?
Yes, needle valves can change the fluid pressure within a system.
What is a throttle valve?
Throttle (needle) valves control the speed of a pneumatic device and adjust the flow rate when the air / liquid is flowing.
