Needle Valves Manufacturers

Needle valves are valves having a small orifice and a threaded, needle-like plunger. It allows precise regulation of flow, and capable of relatively small flow rates. A needle-shaped plunger, on the end of a screw, exactly fits this seat. They are usually used in flow metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time. This valve is usually easy to shut off completely, with merely finger tight pressure. Small, simple needle valves are often used as bleed valves in hot water heating applications.
