Bürkert has expanded its product family of electromotive process valves to include diaphragm valves. The Type 3323 shut-off valve and the Type 3363 control valve are two new additions to Bürkert’s line of electromotive valves for applications without a compressed air supply.
The valves with an electromotive actuator are ideal for applications that do not require compressed air . They feature high control accuracy and highly dynamic control, which allows them to reach the set point exactly and instantaneously with dynamic performance of 4 mm/s. The maximum closing time is below 4.5 s.
A special advantage of the Bürkert solution is a cogging torque controller, which fixes the position of the valve without additional energy consumption. If there is a power outage the safety position can be approached via the optional SAFEPOS energy storage pack.
The field bus capable Type 3323 / 3363 diaphragm valves consist entirely of high-quality components. The linear motion is executed by a brushless DC motor with a planetary gear via a low-friction, permanently lubricated ball screw. This also prevents negative effects from pressure surges, which occur in pneumatic drives.
