Overview
Tiankang Hongji Screwed Bonnet Needle Valves are types of valves used for precise flow control of liquids or gases in a system. It is designed with a long, tapered needle-like plunger that fits into a similarly shaped seat. The valve’s construction allows for very fine adjustments to the flow, making it ideal for applications where precise control is needed.

Applications
- Flow Regulation: Used in systems where the flow needs to be controlled very precisely, such as in gas or liquid pipelines.
- Testing and Calibration: Frequently used in instrumentation, laboratories, and process control applications to calibrate equipment and regulate test fluids.
- Gas and Liquid Distribution: Hongji Needle valves are common in gas and liquid distribution systems, including those in pharmaceuticals, food and beverage, and oil and gas industries.
- Pressure Control: Screwed bonnet needle valves often used for controlling the pressure and flow of sensitive or hazardous fluids in applications like fuel systems, high-pressure systems, or critical fluid handling systems.
