Burkert Type 3361 electromotive 2-way globe control valve (SKU 367302) is the ideal solution for demanding control tasks and 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. If necessary, the safety position can be approached by an optional SAFEPOS energy storage pack in case of a power failure. 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 protection degree and high impact and vibration resistance. The fieldbus-compatible Type 3361 provides helpful functions for process monitoring, valve diagnostics, and predictive maintenance.

Performance Specifications

Operating Limits for Medium Temperature and Operating Pressure

In addition to the maximum operating pressures, the application range of Bürkert process valves is limited by the nominal pressure in accordance with the relevant standard.

Operating Limits for Optional Variants

• High-temperature variant: Suitable for applications with steam, neutral gases, and other heat transfer mediums up to +230 °C.
• Vacuum variant: Without leakage bore, suitable for pressures down to -0.9 bar(g).
• Low-temperature variant: Suitable for minimum medium temperatures down to -40 °C.
• Oxygen variant: Non-metallic wetted materials tested for oxygen suitability up to 25 bar(g) and +60 °C.
• Hydrogen variant: Wetted materials tested for hydrogen suitability up to 40 bar(g) and +100 °C.

Product Design and Assembly

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 are realized with the optional SAFEPOS energy-pack. The desired position is set via the menu.
