Ball valve series
The sphere adopts an integrated structure and the axial positioning of both ends can ensure the concentricity.
Full card buckle design 0 pressure loss design.
The place switch adopts precision connected gold-plated reed to ensure the stability of the on or off signal.
The mechanism seal adopts lateral extrusion seal to solve the problem of end surface deformation.
National invention and many other patents.
Using the piston type sealing mode will not seal more reliable to solve the mechanism shrinkage and expansion problems.
