Angle Type Needle Valve

An angle-pattern needle valve that turns the flow 90° while giving fine throttling and tight isolation on instrument lines.

Overview

The angle-type needle valve combines a right-angle flow path with the fine metering of a needle trim, letting the line change direction by 90° at the valve itself and saving an elbow on tight gauge and manifold hook-ups. A hardened tapered needle is driven into a small integral seat for precise flow regulation and dependable instrument isolation. The compact angle body suits pressure-gauge roots, sampling points and instrument manifolds where space is limited and throttling control matters.
