2/2 way diaphragm valve with electric linear actuator (ON/OFF) made of plastic (Type EVA)
The externally controlled diaphragm valve Type 3323 consists of an electrically controlled linear actuator (open/close), of a diaphragm and a 2 way valve housing. The electric actuator with recirculating ball screw ensures use under hygienic or aggressive environmental conditions. The flow-favorable and dead space-free valve housings enable high flow values and a wide range of possible uses. In the event of a power failure, the safety position is guaranteed by an optional energy storage device. The position is displayed by means of a 360° LED light ring. To protect the diaphragm the actuator has a drive force adjustment. A correspondingly high IP protection IP65/IP67 ensures adequate splash protection. In addition to a fast actuating speed of 1.5 to 4.5 seconds, the actuator is also equipped with a mechanical position indicator and a corresponding explosion protection ATEX/II 3G Ex ec IIC T4 Gc/II 3D Ex tc IIIC T135 °C Dc.
