How to distinguish one-piece, two-piece and three-piece ball valves?

The one-piece ball valve is composed of a ball, a PTFE ring, and a lock nut. The diameter of the ball is slightly smaller than that of the pipe. The two-piece ball valve is composed 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. The three-piece ball valve is composed of three parts, the bonnet and the middle valve body. The three-piece ball valve is different from the two-piece ball valve and the one-piece ball valve in that it is easy to disassemble and maintain. So everyone knows how we distinguish between one-piece and two-piece and three-piece ball valves?

The difference in pressure:

The outer side of the three-piece ball valve is mostly fixed by four bolts, which play a good role in fastening. The precision casting valve body can reach a pressure of 1000psi≈6.9MPa. For higher pressures, forged valve bodies are used. The three-piece pressure resistance is much higher than the one-piece and two-piece ball valves.

Different economic perspectives:

The price of the two-piece ball valve is higher than that of the one-piece type, and the three-piece type valve body is composed of three parts based on higher pressure resistance. The material is higher than the other two types, and the price is higher than expected. The one-piece ball valve has less main body material than the other two types, and the price is favorable, which is the same as the Canton ball valve.

When we all distinguish between one-piece and two-piece and three-piece ball valves, we can distinguish this type of ball valve from the above two points. Choosing a piece-type ball valve that suits us is what we all need.
