PRODUCT DESCRIPTION

5.1

General description

The type 3323, 3324, and 3325 electromotive diaphragm valve is suitable for controlling the flow 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 fieldbus. The electromotive linear actuator is set up such that it is
optimally effective. At the same time, when idling without power, it also keeps the valve sealed even under
the maximum specified 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 configuration with Bürkert Communicator.

Properties

• Hermetic separation of the medium from the actuator by a diaphragm
• Any flow direction.
• Self-draining with appropriate installation. The ends of the connections used must be cylindrical.
• Minimum dead space.
• High flow rate values and low turbulence flow due to the valve body that aids in flow.
• 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.
