Why distinguish between a variety of ball valve it? From the structural distinction between a one-piece ball valve which is integrated inside by the ball, PTFE ring, lock nut composition, the diameter of the ball slightly smaller than the pipe diameter, similar to Cantonese-style ball valve. Two-piece ball valve is composed of two parts, the sealing effect is better than a one-piece ball valve, the diameter of the ball and the pipe diameter of the same than a one-piece ball valve easy to disassemble. Three-piece ball valve is composed of three parts, on both sides of the valve cover and the intermediate valve body, three-ball valve is different from the two-piece ball valve and a ball valve where the place is easy to disassemble and maintain. From the pressure on the distinction between three-piece pressure far higher than the one-piece and two-piece ball valve. The main three-piece ball valve outside by four bolts, play a very good fastening effect. Casting body pressure can reach 1000psi ~ 6.9MPa. Higher pressure is required forging the valve body. From the economic point of view to distinguish a slice of the ball valve as the main body material less than the other two categories, the best price, and wide ball valve use the same. Two-piece ball valve price is higher than a one-piece, three-piece In line with the higher pressure on the valve body consists of three parts, the material is higher than the other two categories, the price is unknown air compressor, compressor.
