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 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. 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.
