Needle Valve
High Performance • Durable
Industrial needle valve for fine flow adjustment and precise isolation in instrumentation and pressure systems.

Key Features & Applications
Small-bore instrument lines often require much finer flow adjustment than a conventional isolation valve can provide. A Needle Valve uses a tapered needle-shaped stem that moves gradually towards or away from a matching seat, allowing controlled adjustment through a narrow flow passage.
Rotating the handwheel advances or retracts the needle through a threaded mechanism. The small opening provides useful adjustment for sampling, pressure measurement and instrument isolation systems where relatively low flow rates are involved.
