The adopts fluid pressure unbalanced trim structure, the top-guided unbalanced trim enable the valve to be featured as single-seated control valve and with dynamic stability of cage-type control valve, where the cage-like guide sleeve has the functions of anti-brushing and anti-cavitation; the quick-release trim combination is very convenient for the replacement of trims. It is suitable for the severe work conditions of small specifications, high pressure difference and high temperature, and very beneficial to various slurry, polymers and high-temperature medium.
