Overview
The Hongji union 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.
