Needle Valves

Needle Valves — New & Used

Needle valves offer fine and precise flow control of gases or liquids by using a tapered needle-like plunger to gradually adjust flow. They’re ideal for low flow, metering, instrumentation, pneumatic and hydraulic control systems where precision and leak-free operation matter.

At Surplus Select, we carry a wide selection of new and used OEM needle valves — in brass, stainless, and alloy materials — available in threaded, compression, or tube-fitting styles. Surplus pricing allows maintenance crews, instrumentation techs, and OEMs to source precise flow-control components affordably for control panels, fluid systems, or pneumatic setups.

Price Match — We match any authorized distributor on identical in-stock parts so you get surplus pricing with distributor-level assurance.

Trade-In Credit — Have quality new surplus items? Trade them in for store credit toward the valve or parts you actually need.

Fast U.S. Shipping — Most orders ship same or next business day so you get valves fast when you need them.

Find Your Needle Valve Fast (Search-First)

Search by valve type or part number (e.g., ¼″ needle valve brass, stainless needle valve 1/8 NPT, instrumentation needle valve used).
No part number? Try keywords like “brass needle valve ⅛ NPT”, “compression tube needle valve”, or “stainless instrumentation valve”.
Use filters such as material, thread type or tube size, connection style, or media type (air, water, oil, gas) to narrow results.

Applications & Use Cases

Instrumentation & control systems: Precisely adjust flow or pressure in gauges, meters, transmitters, and sampling circuits.
Pneumatic & hydraulic systems: Control air or fluid flow in cylinders, regulators, valves, and control loops requiring fine adjustment or shut-off.
Laboratory & test rigs: Use for controlled flow in gas, liquid, or coolant circuits during testing, calibration, or experimental setups.
Maintenance & retrofits: Replace worn valves or upgrade valve fittings in existing fluid or pneumatic systems to restore precise control and leak-free operation.
Custom builds & OEM assemblies: Integrate needle valves into machines, instrumentation panels, or fluid-handling systems to provide reliable control at low-to-medium flow rates.
