Pneumatic Angle Type Unbalanced Multi-Stage pressure drop control valve

Pneumatic Angle Type Unbalanced Multi-Stage pressure drop control valve

Pneumatic Angle Type Unbalanced Multi-Stage pressure drop control valve is suitable for applications with high differential pressure and applications that produce flash evaporation and cavitation. According to the requirements in different service conditions, it is designed with various multi-hole cages that form a multi-stage pressure drop trim, so that the internal energy of high speed media is consumed and flow velocity is reduced from the time when the fluids contact the first cage. As it is composed of various cages, the pressure 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 reatment to prolong the service life of the trim. The valves of large sizes can be designed with the balanced single-seat plug structure.
