Needle valve

A needle valve is a type of valve with a small port and a threade needle -shaped plunger. It allows precise regulation of flow, although it is generally only capable of relatively low flow rates. Choose from our selection of needle valves , including precision flow-adjustment valves , compressed air control valves , and more. In stock and ready to ship. These valves are for instrumentation and general purpose applications up to 0PSI.


How does a needle valve differ from a ball valve?

What are advantages and disadvantages of a needle valve? Why are needle valves used? What is a needleless or needle-free valve? The adjustments are gradual and smooth for controlling the flow rate, however, they can also be used as a reliable shut-off valve.


Pneumatic flow control and needle valves help you regulate air flow in your compressed air system. Get durable plumbing needle valves from Grainger. Packing above the stem thread (PAT) helps provide bubble-tight shutoff.

Stem packing below power thread (PBT) can prevent stem thread contamination and potential lubricant washout. Like most valves , needle valves are responsible for the safe and efficient operation of industrial machinery. They control the flow rate of fluid within a pipeline, but how does a needle valve work?

The distinguishing characteristic of a needle valve is the long, tapere needle like point on the end of the valve stem. Our needle valves can be used as part of a process line – typically alongside other valves – to mix different media into a line, or for venting trapped pressure.


Available in multiple tubing sizes with Vee or regulating stem, and optional materials. Precision flow control valves GRPO. The GRPO is a needle valve that enables precise, infinitely variable regulation of small flow rates in both flow directions. The operation of needle valve requires many turns of the handle to open the valve all the way.


The diameter of the orifice of the valve. The angle of the valve conical needle. The parameter value must be in the range between and 1degrees. These needle valves are an ideal option for isolating or throttling applications.


The self centering, non rotating stem ensures perfect seating.

A variation on the stem-guided globe valve design is the needle valve , where the plug is extremely small in diameter and usually fits well into the seat hole rather than merely sitting on top of it. We position ourselves between manufacturers and suppliers – with on-the-shelf inventory best suited to clients’ needs. Designed for use in high or low pressure installations.


High Pressure Equipment Company has developed a line of High Pressure products to assure safe and easy plumbing for 300 40and 60psi.
