BURKERT Type 3361 (Model 20081535) is an electromotive 2-way globe control valve designed for demanding operating conditions. This specific model features a DN 10 flange connection (DIN EN 1092-1), a stainless steel valve body, and operates on a 24 V DC supply voltage. It is capable of handling pressures from 0 to 25 bar (PN 25 / Class 150) and medium temperatures ranging from -10 °C to +185 °C. The valve provides highly precise, dynamic closed-loop control with a positioning speed of up to 6 mm/s, reacting almost delay-free to process signals. Pressure variations or shocks in the medium are not transferred to the valve position. The closed design and robust surface ensure the hygienic requirements of fast and residue-free cleaning.

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.

WARNING

For device variants with approvals or conformities, deviating technical operating limits (temperature, pressure) may apply. Refer to the corresponding approval-related documentation.

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 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.
