Product description
Types 3320 and 3321
5 PRODUCT DESCRIPTION
5.1 General description
The 2/2-way electromotive valve Type3320 and 3321 is suitable for liquid and gaseous media.
This may be neutral gas, water, alcohol, oil, fuel, hydraulic uid, salt solution, caustic soda, organic solvent
or vapour.
The 2/2-way 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 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
•High seal tightness due to self-adjusting packing gland.
•Devices with PTFE and PEEK material are kept sealed without power.
•High ow rate values due to the stainless steel valve body that aids in ow.
•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 pressure,
except for basic consumption for the control unit.
•Easy and quick replacement of the swivel plate.
•Valve actuator can rotate 360°.
•Integrated control unit.
•High seat tightness due to swivel plate.
•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.

Types 3320 and 3321
6 STRUCTURE AND FUNCTION
The electromotive valve consists of an electromotive linear actuator, a swivel plate and a 2/2 way globe valve
body or a 2/2 way angle seat valve body.
The control electronics and “SAFEPOS energy-pack” are housed in the side of the linear actuator.
The control electronics consist 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 swivel plate.
•The linear actuator is designed such that it does not require any electrical energy to hold the valve
position, i.e. when idling only the control electronics consume energy.
•The stainless steel valve body aids in ow and facilitates high ow rates.
•The self-adjusting packing gland guarantees a high degree of tightness.
The swivel plate is connected to the actuator spindle by a bolt, and is thus easy to replace.
•The actuator housing consists of a robust and heat-dissipating aluminium body with a detergent-resistant
coating. The plastics used are also detergent-resistant.
Valveseat:
The valve seat is always closed against the medium ow. The ow direction must thus be such that the ow
reaches the valve below the seat.

6.2 Valve position after supply voltage failure
ValvepositionfordeviceswithouttheSAFEPOSenergy-packenergystorage:
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 pressure continue to inuence the valve spindle
until it nally idles.
ValvepositionfordeviceswiththeSAFEPOSenergy-packenergystorage:
The valve assumes the safety position dened in the SAFEPOS menu.
For a description of the SAFEPOS energy-pack energy storage system, see chapter “7.2 Energy
storage SAFEPOS energy-pack (option)” on page 21
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 energy storage
accessory.
Thefollowingsafetypositionsareavailabletochoosefrom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.

Image 4: Interfaces of the electromotive valve
The electromotive valve is designed with the three-wire technique, i.e. the electrical supply
(24 V ) is separate from the position signal of the digital input.
