Product feature

A、Using spring load movable seat structure, and preventing the core and seat blocking or breaking away and other problems, the sealing is reliable and the service life is long.
B、Between the V-notch ball core and seat, it has shearing function, especially suitable for medium that containing fibers, tiny solid particles, slurry and so on.
C、When full open, the flow capacity is large, pressure loss is small, and the media will not be deposited in the body cavity.
D、The valve has precise regulation and positioning function, flow characteristic is approximate equal to percentage, adjustable range is large, the largest regulative ratio is 100:1.
