The externally controlled Type 3323 diaphragm valve consists of an electrically controlled linear actuator (open/close), a diaphragm and a 2/2-way valve body. The electric actuator with ball screw ensures usage under hygienic or aggressive ambient conditions. The flow-optimised valve body with minimum dead space enables high flow values and a wide range of possible applications. An optional energy storage device guarantees the safety position in the event of a power failure. The position is indicated by means of a 360° LED light ring. The actuator has a drive force adjustment to protect the diaphragm. A correspondingly high IP protection IP65/IP67 ensures adequate splash protection. The electromotive actuator of the diaphragm valve with ball screw moves to the desired end position at a particularly high speed of up to 4 mm/s. Moreover, the valve is also equipped with a mechanical position indicator and corresponding explosion protection ATEX/II 3G Ex ec IIC T4 Gc/II 3D Ex tc IIIC T135 °C Dc.
