Bürkert offers electromotive seat valves

With the Type 3360/3361 electromotive seat valves, Bürkert offers a complete process control valve that sets new standards with respect to performance, reliability and cost-effectiveness. Potential uses for the new valves include applications with stringent requirements for control accuracy and process stability, as well as applications in which operation without a compressed air system is advantageous.

The special feature of the new Bürkert product family is its performance, which is comparable to that of pneumatic actuators. With a control speed of 6 mm/s and a closing time of less than four seconds Bürkert has improved the previous weak point of many electromotive process control valves, which have control speeds of only 0.1 … 3 mm/s. The Type 3360/3361 valves allow adjustment of the control speed to the requirements of the customer’s specific application, in addition to definition of the stroke and closing limits and soft approach of end positions.

Another positive feature of the electromotive valves compared to pneumatic, spring-balanced actuators is that they travel to the desired position virtually without delay and without overshooting and remain stable regardless of the media pressure. In case of a power outage the safety position can be approached via the optional SAFEPOS energy storage pack.
