PV131 is general model true union ball valve, three different materials for optional, socket connection fit for different standards.
Features of ball valve:
1. Wear resistance; because the core of hard sealing ball valve is alloy steel,
The sealing ring is an alloy steel overweld, so the hard sealing ball valve does not produce much wear when on and off.(Its hardness coefficient is 65-70):
2. Good sealing performance; because the sealing of the hard sealing ball valve is not manually, until the core fully coincides with the sealing ring. So his sealing performance is reliable.
3. The switch is light; because the seal ring bottom of the hard sealing ball valve has a spring to tightly hold the seal ring and the valve core together, so the switch is very light when the outside force exceeds the pretension force of the spring.
4. Long service life: it has been widely used in petroleum, chemical industry, power generation, paper making, atomic energy, aviation, rocket and other departments, as well as people's daily life.
