Stainless steel ball valve

The characteristics of the ball valve include the following: firstly, it is wear resistant; as the spool of the hard seal ball valve is alloy steel spray welded and the sealing ring is alloy steel overlay welded, the hard seal ball valve does not produce much wear when it is switched on and off. (It has a hardness factor of 65-70): Secondly, the sealing performance is good; because the sealing of the hard seal ball valve is manually ground until the spool and the sealing ring are completely matched before use. So his sealing performance is reliable. Again is the switch light; because the seal of the hard seal ball valve uses a spring at the bottom of the seal to make the seal and the spool hold tightly together, so the switch is very light when the external force exceeds the preload of the spring. Lastly, the service life is long: it has been widely used in various sectors such as petroleum, chemical industry, power generation, paper making, atomic energy, aviation, rocket and so on, as well as people's daily life.
