BURKERT 341641 (Type 3361) electromotive 2-way globe control valve is the solution for control tasks under 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 (up to 6 mm/s for the AG2 1300 N actuator) that reacts almost delay-free to process signals. Pressure variations or shocks in the medium are not transferred to the valve position.

This specific model (SKU 341641) features a DN 40 (NPS 1 1/2) welded connection (SMS 3008), a stainless steel body, and a PTFE seat seal. It operates on a 24 V DC supply and includes an integrated positioner function with an equal percentage 50:1 control cone variant.

Product Features

• Highly precise, dynamic closed-loop control: Ensures accurate flow regulation.
• Robust Design: Weather, impact, and vibration-resistant design with an IP65/IP67 and NEMA 4X protection rating.
• Hygienic Surface: Actuator and valve are perfectly adapted to each other with a closed design and robust surface, ensuring fast and residue-free cleaning.
• Vacuum Version: Suitable for pressures down to -0.9 bar(g).

Operating Limits

• Medium temperature: -10 °C to +130 °C
• Ambient temperature: -25 °C to +65 °C

Temperature Dependencies

The maximum permissible temperature for the environment and the medium are dependent on each other. The maximum allowable temperature curves of different device variants are determined for maximum operating conditions (maximum operating pressure and motor power).

Integrated Position Controller

The position of the actuator (stroke) is controlled according to the position set-point value. The position set-point value is specified by an external standard signal (analogue). 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). If there is a system deviation (Xd1), the electric motor drive is controlled via the actuating variable CTRL and the actual position value is changed accordingly.
