China high pressure angle control valve manufacturer, factory and supplier. High pressure angle control valve can be matched with electric acuator or pneumatic actuator. High pressure angle control valve body adopts an angular structure, 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, high pressure angle control valve is designed with various multihole 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.
High pressure angle control valve 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. High pressure angle control valve of large sizes can be designed with a balanced single-seat plug structure.
