Burkert Type 3361 electromotive 2-way globe control valve is designed for highly precise, dynamic closed-loop control under demanding operating conditions. The electromotive actuator with a ball screw positions the control cone with high precision, featuring a positioning speed of up to 6 mm/s that reacts almost delay-free to process signals. The valve body is flow-optimized, and the closed design with a robust surface ensures hygienic requirements for fast and residue-free cleaning. It is highly resistant to weather, impact, and vibration, making it suitable for harsh environmental conditions.

Product Features

• 360° LED Light Ring: A clearly visible 360° LED ring is attached to the blind cover or display module to indicate the device status, the valve end position, and the operating state.
• Mechanical Position Indicator: Shows the current valve position even if the supply voltage fails.
• Mechanical Manual Override: Ensures that the actuator can be operated even if the power supply fails.
• Safety Position via Energy Storage (Optional): The safety starting positions in case of power interruption is realized with the optional SAFEPOS energy-pack. The energy storage device is fully charged and ready for operation after a maximum of 120 seconds.

WARNING

If devices do not have the optional SAFEPOS energy-pack, the valve remains in an undefined position in the event of a power failure. If the valve position is relevant as regards safety, use only devices which have the SAFEPOS energy-pack.
