1. Since the valve and joint are integrated, the number of pipeline components is small, which can shorten the time required for piping operations.
2. Small and easy to use, it has many advantages such as convenient installation, reliable sealing, firm connection, explosion-proof and high pressure resistance level.
3. The stainless steel type is not easy to rust, has corrosion resistance, has long service life and is easy to maintain.
4. Threaded connection, which is more convenient to cooperate with the pressure gauge
5. The pressure resistance and sealing performance are better, and it is easier to control gas and liquid media with smaller flow and higher pressure.
6. Application: Needle valves are widely used in instrument pipelines in the chemical, metallurgical, and power plant industries;
