General description

The electromotive control valve Type 3360 and 3361 is suitable for controlling the flow of liquid and gaseous
media. This may be neutral gas, water, alcohol, oil, fuel, hydraulic fluid, salt solution, caustic soda, organic
solvent or vapour.
The 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 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 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 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 with 2 buttons and 4 DIP switches, or on a display with buttons
for touch operation. It is also always possible to set the device with the büS service interface and by using
the software Bürkert Communicator. The USB büS interface set, available as an accessory, is required for
configuration with Bürkert Communicator.
One special characteristic of the Type 3361 globe control valve is the screwed-in valve seat, which can be
replaced to reduce the seat size.

Properties

• High seal tightness due to self-adjusting packing gland.
• Devices with PTFE seal material are kept sealed without power.
• High flow rate values due to the stainless steel valve body that aids in flow.
• External, directly accessible display with buttons for touch operation.
• 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 control cone.
• 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.
