Bürkert Electromotive 2/2-WAY Tank Bottom Diaphragm Valve (On/off)

Bürkert Type 3325 The externally controlled Type 3325 diaphragm valve consists of an electrically controlled linear actuator (on/off), a diaphragm and a tank bottom 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 rates and a wide range of possible applications. 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. The electromotive actuator of the tank bottom diaphragm valve with ball screw moves to the desired end position at a particularly high speed up to 4 mm/s. In addition 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. Deployed in process, utility and marine piping loops for on-off shutoff, control, safety relief or diversion service.
