Product description
Type 3323, 3324, 3325
5 PRODUCT DESCRIPTION
5.1 General description
The type 3323, 3324, and 3325 electromotive diaphragm valve is suitable for controlling the ow of liquid
and gaseous media. These can be neutral, ultra-pure, sterile as well as contaminated, aggressive or abrasive
media of high to low viscosity.
The valve has an electromotive linear actuator with the actuating electronics assembly, which is actuated
either via binary signals or (digitally) via a eldbus. The electromotive linear actuator is set up such that it is
optimally eective. At the same time, when idling without power, it also keeps the valve sealed even under
the maximum specied operating medium pressure.
The device can also be equipped with the energy storage system (SAFEPOS energy-pack). In the event of a
supply voltage failure, the energy storage system supplies the actuator with the energy required to move the
valve to the desired position, which can be set in the menu.
The valve position can be manually changed in two ways.
1. Electrical manual override: used if supply voltage is present.
2. Mechanical manual override: must only be used if there is no supply voltage present.
The device can be operated with 2 capacitative buttons and 4 DIP switches. It is also always possible to set
the device with the büS service interface and by using the PC software Bürkert Communicator. The USB büS
interface set, available as an accessory, is required for conguration with Bürkert Communicator.
5.2 Properties
•Hermetic separation of the medium from the actuator by adiaphragm
•Any ow direction.
•Self-draining with appropriate installation. The ends of the connections used must be cylindrical.
•Minimum dead space.
•High ow rate values and low turbulence ow due to the valve body that aids in ow.
•Easy and quick replacement of the diaphragm. PTFE/EDPM diaphragms can be replaced by EPDM
diaphragms.
•Mechanical position indicator shows the valve position even in the event of a supply voltage failure.
•360° LED light ring for displaying device states, valve end positions and operating state.
•No electrical energy is required to hold the valve position even under maximum operating medium
pressure, except for basic consumption for the control unit.
•Valve actuator can rotate 360°.
•Integrated control unit.
•Contact-free, high-resolution and wear-free position sensor.
•The actuator housing consists of a robust and heat-dissipating aluminium body. The coating is resistant to
common detergents. The plastics used for the actuator housing are also detergent-resistant.
5.3 Variants
The following body variants are described in these instructions:
•Type 3323: 2-way valve body
•Type 3324: T-valve body
•Type 3325: Tank bottom body
English

Product description
Type 3323, 3324, 3325
5.4 Options
•Energy storage system (SAFEPOS energy-pack) for reaching safety position.
The safety position that the valve is supposed to take in the event of a supply voltage failure is specied
with the DIP switch.
•SIM card for saving and transmitting device-specic values and settings.

Structure and function
Type 3323, 3324, 3325
6 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 eldbus (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, ange connection, clamp connection or bond connection
(connection sizes on request).

6.2 Valve position after supply voltage failure
ValvepositionfordeviceswithouttheSAFEPOSenergy-pack:
If the electromotive actuator idles upon a supply voltage failure, the valve remains in the last position that it
was in.
If the supply voltage fails while the actuator is changing the valve position, the valve remains in an undened
position. The ywheel mass of the actuator and the operating medium pressure continue to inuence the valve
spindle until it nally idles.
ValvepositionfordeviceswiththeSAFEPOSenergy-pack:
The valve adopts the safety position dened by the DIP switch position.
For a description of the SAFEPOS energy-pack, see chapter “7.2” on page 22
6.3 Safety position
The DIP switch denes the safety position that the valve assumes in the following scenarios:
•Internal error
•Supply voltage failure (optional)
This function is only available for devices that have the optional SAFEPOS energy-pack accessory.
ThefollowingsafetypositionsareavailableforselectionforSAFEPOS:
•Close = valve closed
•Open = Valve opened
•Inactive = valve remains in an undened position in the event of a supply voltage failure.

7 CONTROL ELECTRONICS
7.1 Function
The actuator (stroke) position is controlled by the digital input. The position is specied either by en external
signal (analogue) or via a eldbus (digital).
The position sensor records the current position of the electrical linear actuator and from this creates an end
position signal via the digital outputs.
Technicalcharacteristics:
•Positionsensor
contact-free, high-resolution and wear-free.
•Microprocessor-controlledelectronicsassembly
for signal processing, control and motor control.
•Electricalinterfaces
Circular plug-in connector or cable gland
