Burkert 20120848 (Type 3361) is an electromotive 2-way globe control valve designed for highly precise, dynamic closed-loop control under demanding operating conditions. This specific model features a 3/8" RC internal thread connection, a stainless steel body, and a hardened stainless steel seat seal. It is equipped with an AG2 actuator (1300 N driving force) operating on 24 V DC, providing a positioning speed of up to 6 mm/s. The valve is suitable for operating pressures from 0 to 25 bar and medium temperatures ranging from -10 °C to 185 °C. It includes an electrical energy storage return type and offers an equal percentage 50:1 control cone variant.

The innovative process controller valve Type 3361 features an electromotive actuator with a ball screw that positions the control cone with the highest precision. It reacts almost delay-free to process signals. The closed design and robust surface ensure the hygienic requirements of fast and residue-free cleaning.

Performance Specifications

Flow Characteristics

• Control cone variant: Equal percentage 50:1
• Flow direction: Below seat (against closing direction)

Operating Limits

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 (PN 25 / Class 150).

Product Design and 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 by standard signals (1 analogue input + 1 digital input).
