Hydraulic Flow Control Valve 1/2″ Female 6000 psi SS Needle Valve
* Needle valves are used to accurately control flow rate, but can also be used as a reliable shut-off valve.
* Most commonly, needle valves are operated manually, but they can be motorized to allow for automation.
* The main selection criteria for a needle valve are: pressure, size, temperature, and materials.
* A disadvantage of needle valves is the relatively large pressure drop.
Needle valves are used to accurately control flow rate. They are also suitable as reliable shut off valves. Common sizes are from
1/8” up to 2”. Adjustments are gradual and smooth. A disadvantage of needle valves is the relatively large pressure drop.
