PNEUMATIC ANGLE CONTROL VALVE FEATURE
Pneumatic angle control valve is specially designed for the medium which is high viscosity, easy to crystallize, containing suspended particles and 90 degree angle area.Pneumatic angle control valve can choose single seat or balanced sleeve disc,which can be used on some high pressure differential or multistage adjustment. -
Pneumatic angle control valve main advantage as below:01.Pneumatic Angle Control Valve is used for large viscosity, easy crystallization,and easy coagulation situation, etc.02.Actuator of Pneumatic angle control valve adopts multi-spring circular equal layout, using high strength rubber diaphragm actuation parts, with small structure and large output force03. Small pressure differential loss, accurate flow control04.No dead corner in the Pneumatic angle control valve, easy to clean, also applicable for food industry.
