The Z73X manual slurry valve is available in clamp-on and integral versions, and the clamp-on body seal adopts a composite configuration of "U" and "T" composite structures. The integral valve body seal adopts the "O" composite sealing ring structure, which overcomes the shortcomings of the original clamp-on slurry valve using "U" type sealing gasket that is easy to shift and deform after being stressed, and the media leakage of bevel gear slurry valve.
