Needle valves within a block and bleed function help achieve positive isolation with a variety of applications, and play an integral role in ensuring the overall efficiency of your fluid or low pressure system. Learn more about the function of needle valve systems, as well as the benefit of Hy-Lok’s components below.

How Do Needle Valves Work

Functionally, needle valves are similar to shutoff valves, and are used to start, stop, and regulate the flow rate of liquids and gas within a pipeline. Unlike shutoff valves, however, needle valves are long and tapered, with a “needle”-like point at the end of the valve. Because of their unique design, needle valves are able to precisely control how much fluid passes through the valve.

Depending on the design on the component, needle valves can operate manually or automatically. Manually operated needles use a hand wheel to stop or stop the flow of fluid, as well as control the amount passing through the valve at once.

Automated needle valves are connected to a hydraulic motor or air actuator that opens and closes the valve. Both manual and automatic valves provide precise flow rate control, making them ideal for a wide variety of applications, including: medical research facilities, oil & gas, chemical processing plants, and more.
