STRUCTURE AND FUNCTION

The electromotive diaphragm valve of Types 3323, 3324 and 3325 consists of an electromotively driven linear
actuator, diaphragm and a diaphragm valve body.
The control electronics and "SAFEPOS energy-pack" are housed in the side of the linear actuator.
The control electronics assembly consists of the microprocessor-controlled electronic mechanism and the
position sensor.
Actuation occurs via binary signals (analogue) or fieldbus (digital).
The electromotive valve is designed with the three-wire technique. Operation is performed with 2 buttons and
4 DIP switches.
The electromotive linear actuator consists of a brushless direct current motor, a gear and a threaded spindle.
The valve spindle connected to the threaded spindle transfers the force to the compressor and the diaphragm.
The linear actuator does not use any electrical energy when holding the valve position. This means that, when
idling, only the control electronics require energy.
Port connections:
Welded connection, threaded socket connection, flange connection, clamp connection or bond connection
(connection sizes on request).
