The ball valve opening and closing part (ball) is driven by the valve stem and rotates around the ball valve shaft. It can also be used for fluid regulation and control, among which the V-shaped ball core of the hard-sealed V-shaped ball valve and the metal valve seat of hard alloy surfacing has strong shear force, especially suitable for media containing fibers and micro-solid particles. The multi-port ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium, but also can close any channel to connect the other two channels. Such valves should normally be installed horizontally in the pipeline. The ball valve is divided into a pneumatic ball valve, electric ball valve, and manual ball valve according to the driving mode.
Features of a PVC manual double by-order ball valve:
1. Wear resistance: Since the valve core of the hard-sealed ball valve is spray-welded with alloy steel, and the sealing ring is welded with alloy steel, the hard-sealed ball valve will not wear too much during switching (the hardness coefficient is 65-70).
2. The sealing performance is good; because the sealing of the hard-sealed ball valve is artificially ground, until the valve core and the sealing ring are completely consistent. So his sealing performance is reliable.
3. The switch is light; since the bottom of the sealing ring of the hard-sealed ball valve uses a spring to tightly connect the sealing ring with the valve core, when the external force exceeds the preload of the spring, the switch is very light.
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.
