High speed, precision control

Bürkert claims that its Type 3360/3361 electromotive seat valves offer a complete process control valve that sets new standards with respect to performance, reliability and cost-effectiveness. Potential uses for the valves include applications with strict requirements for control accuracy and process stability, as well as applications where the use of compressed air systems is impossible.

The valve ranges’ performance is said to be comparable to that of pneumatic actuators. With a control speed of 6mm/s and a closing time of less than four seconds, Bürkert says it has improved the previous weak point of many electromotive process control valves, which have control speeds of only 0.1 to 3mm/s. The valves allow adjustment of the control speed, definition of the stroke and closing limits and soft approach of end positions to the requirements of the specific application.

Another positive feature of the electromotive valves compared to pneumatic, spring-balanced actuators is that they travel to the desired position without delay and without overshooting and remain stable regardless of the media pressure.

In view of the trend toward ‘Industry 4.0’ the Type 3360/3361 valves can be integrated into a central network.
