BURKERT Type 3361 (SKU 20076065) is an innovative electromotive 2-way globe control valve designed for demanding operating conditions. The electromotive actuator with a ball screw positions the control cone with the highest precision. A unique feature is its high positioning speed of up to 6 mm/s, which reacts almost delay-free to process signals and can be varied according to customer demands. Pressure variations or shocks in the medium are not transferred to the valve position.

Each flow-optimized valve body can be equipped with up to 5 different valve seats for precise adaptation to customer needs. The actuator and valve are perfectly adapted to each other with a closed design and robust surface, ensuring the hygienic requirements of fast and residue-free cleaning. Harsh environmental conditions are no problem for the Type 3361 due to its IP65/IP67 degree of protection and high impact and vibration resistance. The fieldbus-compatible Type 3361 provides many helpful functions for process monitoring, valve diagnostics, and predictive maintenance.

Product Design and Assembly

Safety Position via Energy Storage (Optional)

The safety starting positions in case of power interruption are realized with the optional energy storage SAFEPOS energy-pack. The desired position is set via the menu. In addition to the end positions (open/closed), any desired intermediate position can be defined here. The energy storage has a lifespan of up to 10 years, depending on the operating conditions. The power of the energy storage is monitored, and a warning is displayed to indicate its service life is coming to an end. The storage device is designed as a plug-in module to facilitate replacement.
