BURKERT 20091306 (Type 3361) electromotive 2-way globe control valve is the solution when it comes to control tasks under demanding operating conditions. The electromotive actuator with ball screw positions the control cone with highest precision. A unique feature is its high positioning speed up to 6 mm/s that reacts almost delay-free to process signals and that can be varied according to customer demands. Pressure variations or shocks in the medium are not transferred to the valve position.

Each flow optimised valve body can be equipped with up to 5 different valve seats for a precise adaptation according to customer needs. The 20091306 model features a DN 40 clamp connection, an AG2 actuator (1300 N), and an integrated positioner function with büS and PROFINET communication. Actuator and valve are adapted perfectly to each other with a closed design and robust surface. This ensures the hygienic requirements of fast and residue-free cleaning. Harsh environmental conditions are no problem for the Type 3361 because of the degree of protection IP65/IP67 and its high impact and vibration resistance.

Product Features

• Highly precise, dynamic closed-loop control: Equal percentage 50:1 flow characteristic.
• Robust Design: Weather, impact, and vibration resistant design (IP65/67, NEMA 4X).
• Hygienic: FDA-compliant materials and easy-to-clean surface.
• Safety: Normally closed delivery status with electrical energy storage (SAFEPOS energy-pack).
• Communication: Integrated fieldbus gateway supporting büS and PROFINET.

Product Assembly

The electromotive linear drive consists of a brushless DC motor, a gear and a spindle system that transfers the force to the closing element. The integrated electronics are controlled either by standard signals or via a fieldbus (digital). The electromotive linear actuator is designed to provide optimum efficiency. At the same time, it keeps the valve tight and in position even at the maximum specified medium pressure in a powerless standstill.

Integrated Position Controller

The position of the actuator (stroke) is controlled according to the position set-point value. The position set-point value is either given by an external standard signal (analogue) or via a fieldbus (digital). The displacement transducer records the actual position (POS) of the electric linear actuator. The positioner compares the actual position value with the position set-point value (CMD) specified as standard signal.
