1/2 Inch 201 NPT
1. Wear-resistant; because the spool of the hard-sealed ball valve is spray-welded alloy steel, three-piece ball valve
The sealing ring is made of alloy steel surfacing, so the hard-sealed ball valve will not produce too much wear when it is switched on and off.
2.Second, the sealing performance is good; because the sealing of the hard-seal ball valve is manually ground, it can not be used until the valve core and the sealing ring are completely matched. Therefore, its sealing performance is reliable.
The pneumatic ball valve has a simple and compact structure, reliable sealing, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state, which is not easy to be eroded by the medium. It is easy to operate and maintain. It is suitable for general working media such as water, solvent, acid and natural gas. It is mainly used for cutting off. Or connect the medium in the pipeline, and can also be used for fluid adjustment and control.
