Bürkert new electromotive shut-off valves

Bürkert, with North American headquarters in Huntersville, North Carolina, has introduced two new types of electromotive process valves to its range of actuator components. After introducing the Type 3360 and 3361 control valves, the Ingelfingen-based fluidics experts now present the Type 3320 (angle seat valve) and Type 3321 (globe valve) electromotive on/off valves. These shut-off valves 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 valves of the Bürkert ELEMENT product family.

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.
