Needle Valve

The needle valve is a kind of valve that can accurately adjust the flow rate and belongs to the globe valve. Its valve core is a slender needle shape. By rotating the valve stem to drive the needle valve core up and down, it changes the gap between the valve core and the valve seat, so as to realize the fine adjustment of small flow and low flow rate medium. The needle valve has good sealing performance, sensitive adjustment and high precision. It is mainly used in instrument measuring pipelines, hydraulic systems, petrochemical industry, laboratory equipment and other occasions that need accurate flow control, and also often used as pressure tapping valves before pressure gauges and transmitters.
