The innovative process controller Bürkert valve Type 3361 is the solution when it comes to demanding control tasks and 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 fluctuations or surges 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. If necessary, the safety position can be approached by an optional energy storage in case of power failure. Actuator and valve are adapted perfectly to each other with 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 protection class IP65/IP67 and its high impact and vibration resistance. Unrivalled service life and tightness is guaranteed by the proven self-adjusting packing gland with exchangeable V-seals. The fieldbus-compatible Type 3361 provides many helpful functions for process monitoring, valve diagnostics and predictive maintenance and therefore offers the decisive advantage of a modern process automation.
