You will notice needle valves across all fluid Management programs because of their capability to precisely Manage flow rates. By picking out the suitable valve material and size for temperature and force, they can be utilized for nearly any thoroughly clean fuel or fluid.
The two manually operated and automated needle valves deliver exact Charge of the flow amount. The handwheel is finely threaded, meaning it's going to take a number of turns to adjust the situation from the plunger. Due to this fact, a needle valve may help you superior control the stream charge of fluid during the program.
