Diaphragm Actuators

Product DescriptionThe BEIER L4-series is a pneumatic multi-spring diaphragm actuator with spring return(fail safe) and is used to actuate linear valves. The actuator positions the valve plug, which in turn is controlled by a pneumatic or electro-pneumatic positioner. These actuators can be operated in the "Air to open" function or with the reverse action "Air to close"Product Features(1)The Actuator has a compact design with a low installed height. Various Spring sets with different ranges ensure good adaptation to the relevant operation conditions(2)A fabric-reinforced diaphragm ensures smooth conversion of the pneumatic application of pressure into the linear motion of the actuator spindle. The diaphragm, supported by the diaphragm disc,is connected to the actuator spindle and separates the actuator housing into pressure and spring chambers. If the force of the compressed air control signal chambers. If the force of the compressed air control signal exceeds the opposing spring force, the actuator spindle moves and actuates the linear valve.(3)The control signal is carried to the diaphragm chamber via interal channels in the yoke. The air supply and venting of the spring chamber is carried out by means of the protective cap, which is impermeable to splash water, or the chamber is purged through internal channels with the air from the positioner.(4)The yoke connects the actuator to the control valve, while the actuator spindle is connected to the valve spindle via the coupling shown as a stroke indicator, securely guided in the slide bearing and sealed with a special sealing element with wiper.
