Pneumatic Diaphragm Cage Guided Linear Angle Control Valve

The valve body of the pneumatic diaphragmcage guided linear angle control valveis a right-angled shape, and the valve plug has a single guiding structure. The valve body has a simple flow path and low resistance, and角控制阀is generally used in the case of bottom-in and side-out, because the stability can be better. Pneumatic diaphragm cage guided linear angle control valve is specially designed for applications where the viscosity of the medium is large, easy to crystallize, contains suspended particles, and 90 degree bend joints. Because the angled valve body has no dead angle, it is easy to purge, and the maintenance is simple and widely used. It can use single or balanced cage plug can, and if some high pressure differentials,it can use multi-stage regulation.

Working Principle of Angle Control Valve:

The pneumatic diaphragm angle control valve is mainly composed of a pneumatic diaphragm multi-spring actuator and an angle valve. The compressed air is used as the power source, and the accessories are positioners, converters, solenoid valves, and retaining valves. The signal automatically controls the opening of the valve to achieve the regulation of media flow, pressure and level. The equal percentage characteristic is optimal, the regulation is stable, and the adjustment performance is good.

Under normal circumstances, the angle control valve is installed in the forward direction, that is, bottom-in and side-out. Only in the case of high pressure difference and high viscosity, easy coking, and suspended particulate media, reverse installation is recommended,that is,and side-in bottom-out. The purpose of the reverse use of the angle control valve is to improve the imbalance force and reduce the wear on the valve plug, and also to facilitate the flow of high viscosity, easy coking and suspended particulate medium, avoiding coking and clogging.
