General description

The Type 3363, 3364 and 3365 electromotive diaphragm control 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 diaphragm control valve has an electromotive linear actuator with actuation electronics assembly. The
actuation electronics assembly for position control or process control is actuated either via standard signals
(analogue) or via a fieldbus (digital). 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 and in position even under the
maximum specified 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 position defined in the SAFEPOS 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 set and operated either via 2 capacitive buttons and 4 DIP switches, or on a display with
a touchscreen. It is also always possible to set the device with the büS service interface and by using PC
software Bürkert Communicator. The USB büS interface set, available as an accessory, is required for confi-
guration with Bürkert Communicator.

Properties

• Hermetic separation of the medium from the actuator by a diaphragm.
• Any flow direction.
• Self-drainage 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.
• External, directly accessible display with touchscreen.
• 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 for position control or process control.
• 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.
• Easy and quick replacement of the diaphragm. PTFE/EDPM diaphragms can be replaced by EPDM
diaphragms.
