High pressure ball valve body structure, combined with high-pressure-bearing components, ensures the safe and reliable operation under the high pressure of 10 MPa and above.

Parabolic cylinder core structure has excellent sealing and regulation performance, large flow capacity, broad range of adjustment and high precision of flow curve.

Solid porous bushing prevents flash distillations, cavitations and the damages.

Generally applicable to the high-pressure situations and the control of the media containing particle impurities (under high pressure)
