The advantages of electromotive actuators are receiving more attention in process automation. As simple, smart systems they offer diverse opportunities for process optimisation. 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. In addition, the possibility of emergency manual movement also exists. In view of the trend toward “Industry 4.0” the Bürkert Type 3360/3361 valves fulfil the increasing customer requirements with respect to the diagnosis of process and valve data as well as the capability of optimal integration in a central company network.

Application focuses and customer benefits

Bürkert’s development of the electromotive process control valves is intended for applications in which the use of compressed air is not desired or not possible. Examples of such applications include large-area storage systems with long distances to the single valves, as well as systems for mobile, decentralised water treatment. Another customer benefit is to be found in applications with stringent requirements for control accuracy and speed, together with minimal dead time, such as in engine test rigs.
