Product Overview
The Bürkert Type 3285 is a motor-operated proportional valve engineered for precise, continuous modulation of neutral and aggressive media in industrial process and pneumatic control systems. Featuring a 12.0 mm nominal orifice and FKM (fluoroelastomer) sealing, this valve delivers accurate flow control proportional to an analog input signal via its integrated stepper motor actuator. The NPT 3/4 connection and PN 6 bar pressure rating make it suitable for low-pressure process lines requiring high-resolution flow adjustment. With a stainless steel (VA) body, the 3285 C is particularly suited for corrosive media and demanding hygienic or chemical environments. As a direct-acting proportional valve, it provides excellent repeatability and minimal hysteresis without the need for minimum differential pressure, ensuring reliable performance across a wide range of industrial applications.
