According to the requirements in different service conditions, it is designed with various multi-hole cages that form a multi-stage pressure reduction trim, so that the internal energy of high speed media is consumed and flow velocity is reduced from the time the fluids contact the first cage. As it is composed of various cages, the pressure is gradually reduced so that the medium pressure is always above the saturated vapor pressure, and the occurrence of flash evaporation and cavitation is eliminated. The standard configuration is the unbalanced single-seat plug and the plug and seat are subjected to hardening treatment to prolong the service life of the trim. The valves of large sizes can be designed with the balanced cage valve structure.
