KAM series pneumatic angle valve control valve spool is rectangular in shape, not only guide structure, the valve flow path is simple, easy cleaning and cleaning. The resistance is small, suitable for from the viscosity, regulating the particulate matter containing suspended solids and fluids, to avoid coking, adhesion, jam, automation control is widely used in petroleum, chemical industry, light industry production process.
General pneumatic angle of main technical parameters of shape adjusting valve actuator:
