Needle Valves
The needle valve made by Hongji Instrument& Valve Manufacturing Co., Ltd. is a type of valve with a small port and a threaded, needle-shaped plunger. It allows precise regulation of flow, They are also usually used in flow-metering applications, especially when a constant, calibrated, flow rate must be maintained for a certain duration, such as the idle fuel flow in a carburetor, steam in the pipe from the power plant, as well as to provide shut off for the pressure gauge or on applicators in many industries.
1. Needle Valve Features& Applications:
- Accurate& Precise control flow rate and pressure.
