New electromotive shut-off valves from Bürkert

Two new types in the product family of electromotive process valves expand Bürkert’s range of actuator components. After introducing the Type 3360 and 3361 control valves, the Type 3320 (angle seat valve) and Type 3321 (globe valve) electromotive on/off valves are now being released. These shut-off valves set new standards with respect to performance, reliability and cost effectiveness and are ideal for applications without compressed air supply.
The addition of the new Type 3320 / 3321 shut-off valves to Bürkert’s process valve product range now makes it possible to switch systems entirely to electromotive actuators. The two on/off valve types feature convincing efficiency that is equal to that of pneumatic actuators. And the electric actuator uses the same time-proven valves of the Bürkert ELEMENT product family. This means that the actuators are even interchangeable. A special advantage of the Bürkert solution is an innovative cogging torque brake, 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. A mechanical position indicator with a 360° LED clearly indicates the position and status of the valve at all times. In addition, the possibility of a manual override also exists. The closing speed is adjustable in order to protect field devices and pipes against pressure shocks. The electromotive on/off valves respond instantaneously to process signals to guarantee fast shut-off of the flow within 3-4 seconds, if necessary.
