3.Manual Ball Valve classification:

1) The two-piece Manual Ball Valve consists of two parts, and the sealing effect is better than that of the one-piece ball valve. The diameter of the ball is the same as that of the pipe, and it is easier to disassemble than the one-piece ball valve.
2) The three-piece Manual Ball Valve consists of three parts, the valve cover on both sides and the middle valve body, which is convenient for disassembly and maintenance. Stronger pressure resistance.

4.Features of Manual Ball Valve:

1) The Manual Ball Valve is wear-resistant; since the hard-seal valve core of the Manual Ball Valve is spray welded with alloy steel, and the sealing ring is welded with alloy steel, the hard-seal Manual Ball Valve will not produce too much wear when it is switched on and off.
2) The Manual Ball Valve has good sealing performance; because the manual ball valve is sealed by manual grinding, it cannot be used until the valve core and the sealing ring are completely matched. Therefore, its sealing performance is reliable.
3) The Manual Ball Valve switch is light and has a long service life;


5.Manual Ball Valve application:

In addition to being used in people's daily life, Manual Ball Valve can also be used in various industries such as petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets, etc. It is suitable for various media such as water, solvents, acids and natural gas.
