Characteristics and uses:
1. Wear-resistant: Because the spool of hard seal ball valve is alloy steel spray welded, and the seal ring is alloy steel surfacing welded, so the hard seal ball valve will not produce too much wear and tear when switching on and off. (Its hardness coefficient is 65-70):
2. Good sealing performance: Because the sealing of hard seal ball valve is manually ground until the spool and the seal ring are completely matched before use. So his sealing performance is reliable. The down-mounted stem and stem head bumps prevent the stem from spraying out, and if fire causes damage to the stem seal, metal contact can also be formed between the bumps and the valve body to ensure the stem seal.
3. light switch: because the hard seal ball valve sealing ring at the bottom of the spring so that the seal ring and the spool tightly held together, so in the outside world more than the spring preload switch is very light.
4. long service life: due to polytetrafluoroethylene and other materials have good self-lubrication, and the ball friction loss is small, so the ball valve has a long service life.
5. It has been widely used in various sectors such as petroleum, chemical industry, power generation, paper making, atomic energy, aviation, rocket, etc., as well as in people's daily life.
6: Anti-static function: the spring is set between the ball, valve stem and valve body, which can lead out the static electricity generated during the switching process.
