Tips

High quality Needle Valve can operate manually or automatically. Manually operated needle valves use the handwheel to control the distance between the plunger and the valve seat. When the handwheel is turned in one direction, the plunger is lifted to open the valve and allow fluid to pass through. When the handwheel is turned in the other direction, the plunger moves closer to the seat to decrease the flow rate or close the valve.

Automated needle valves are connected to a hydraulic motor or an air actuator that automatically opens and closes the valve. The motor or actuator will adjust the plunger’s position according to timers or external performance data gathered when monitoring the machinery.

Both manually operated and automated Needle valves provide precise control of the flow rate. The handwheel is finely threaded, which means it takes multiple turns to adjust the position of the plunger. As a result, a needle valve can help you better regulate the flow rate of fluid in the system.
