Manual Flange Ball Valve
Introduction:
The valve body casting of flange ball valve is made of silica sol, and the high platform valve body does not need to be made of brackets, which will not cause torque errors, so that the valve cannot be opened or closed. The sphere has high processing precision, it is a solid sphere, and the excess material is not easy to remain and will not cause pollution.
Features:
1. Wear-resistant; since the valve core of the hard-sealed ball valve is spray welded with alloy steel, and the sealing ring is surfacing with alloy steel, the hard-sealed ball valve will not cause much wear when it is switched on and off.
2. Good sealing performance; since the sealing of the hard-sealed ball valve is artificially ground, it cannot be used until the valve core and the sealing ring are completely matched. So his sealing performance is reliable.
3. The switch is light; since the bottom of the sealing ring of the hard-sealed ball valve adopts a spring to hold the sealing ring and the valve core tightly together, the switch is very light when the external force exceeds the preload of the spring.
4. Long service life: It has been widely used in petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rocket and other departments, as well as people’s daily life.
