Needle valve is an important part of instrument measurement pipeline system, mainly including globe valve and ball valve. Its function is to open or cut off the pipeline. The ferrule type instrument valve has the advantages of convenient installation and disassembly, tight connection, fire protection, explosion-proof, high pressure resistance and good sealing performance. It is an advanced connection mode valve in power station, oil refining, chemical plant and instrument measurement pipeline. The needle type globe valve has good sealing performance and long service life. Even if the sealing surface is damaged, it only needs to replace the vulnerable parts to continue to use.
1. The product has reasonable structure, reliable sealing, excellent performance and beautiful appearance.
2. The sealing surface is overlaid with Co based cemented carbide, which has good wear resistance, corrosion resistance, scratch resistance and long service life.
3. After quenching and tempering and surface nitriding treatment, the valve stem has good corrosion resistance and scratch resistance.
4. The valve is equipped with reverse sealing structure, which is reliable.
5. Parts material and flange size can be reasonably selected according to actual working conditions or user requirements to meet various engineering needs.
