Principle
Regulator in the throttling process in the throttled position, mainly between the valve core seat, produce the effect such as cavitation, cavitation, erosion, on regulating valve material damage, labyrinth trim control valve is formed in the medium access labyrinth channels in the valve, the throttle position dispersion and concentration between the valve core seat, and thus to minimize damage to the valve core seat,Then improve the life of the valve or reduce the material requirements of the valve core seat.
