PVC Ball Valve and PVC Pipe Fitting

PPH Ball Valve is a high reliability ball valve, the ball valve has a high sealing, especially in the ball valve after the long period of use of its seal reliability is still high, can effectively avoid due to the sealing ring hardening or deformation caused by fluid leakage.

The PPH Ball Valve comprises a valve body, a stem, a sphere and a sealing ring, wherein the sphere is connected to the stem and a pneumatic drive is connected to the stem. The sealing ring is a left and right two, and the sealing ring is glued to the seat of the valve body, the sealing ring comprises a buffer layer and a sealing layer, the side of the buffer layer is bonded to the seat, the other side of the buffer layer is bonded to the sealing layer, and the sealing effect of the ball valve is effectively improved by sticking a buffer layer between the sealing layer and the seat of the sealing ring, and when the ball valve is used for a long time, After the sealing layer is deformed or hardened, the elastic ball in the buffer layer can still make the sealing layer of the sealing ring close to the closed sphere, enhance the reliability of the ball valve seal, and prolong the service life of the ball valve.
