The externally controlled diaphragm valve Type 3323 consists of an electrically

controlled linear actuator (open/close), of a diaphragm and a 2/2-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 ?ow 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. The electromotive actuator of the 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 a corresponding explosion protection ATEX/II 3G Ex ec IIC T4

Gc/II 3D Ex tc IIIC T135 °C Dc.
