Shanghai Thinktank Process Management Co., Ltd Pneumatic Angle Type Control Valve

Description Model HAP series angle type 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, it 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. 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 a balanced single-seat plug structure. STANDARD SPECIFICATION Trim feature Sleeve guided unbalanced trim structure, a combination of multi-hole cages Body type Straight-through type, angle type Bonnet type Standard type, heat dissipation type, cryogenic type, bellows Flow characteristic: Equal percentage, linear, quick open Shut-off class ASME B16.104 V (standard metal seat) ASME B16.104 VI (shut-off soft seat) Connection type The flange type, butt welding type Applicable temperature range -196°C – 570°C Actuator type Pneumatic diaphragm actuator Pneumatic piston actuator Electric actuator What Is The Difference Between Pressure Control Valve and Flow Control Valve
