Precise, hygienic and dynamic switching and control

Bürkert product spectrum expanded to include electromotive 2-way membrane valves

electromotive 2 way membrane valves Type 3363 3323

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, which – especially for applications without a compressed air supply – set new standards with respect to performance, reliability and cost-effectiveness.

The valves with an electromotive actuator are ideal for applications that either do not require compressed air or for which compressed air is not available due to the difficulty of conveying it to the application. 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. Overshooting or undershooting, which can occur with pneumatic valves, is not possible. Integration of the piloting function in the compact drive eliminates the need for control cabinet installation, as well as field piping and the power supply for the compressed air. The electromotive drive principle allows adaptation of the driving force to the respective application, which increases the life of the diaphragms and maintenance intervals, thus reducing maintenance costs.

Safety is the top priority

The electromotive drives can be combined with diverse standard bodies and diaphragms of the Bürkert family of pneumatically operated products. Electromotive valves are very cost-effective due to their low energy costs and savings throughout the entire system. A special advantage of the Bürkert solution is an innovative 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 safety position can also be adapted to the particular process. A mechanical position indicator with a 360° LED clearly indicates the position and status of the valve at all times.

Hygienic, high-quality and durable

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. The robust powder-coated aluminium body with protection type IP65/IP67 features an easy-to-clean and closed design. The shut-off and control valves are resistant to weather, impacts and vibrations, which makes them ideal for use in harsh environments.

Ideal for hygienic applications

The new Bürkert electromotive diaphragm valves are offered as a shut-off valve (Type 3323) and as a control valve (Type 3363), in diameters up to DN50. The FDA, USP and EHEDG compliant valves are especially suitable for cleanroom, filling, packaging and CIP/SIP applications in the pharmaceutical and health care sectors, for use in the dairy and cosmetics industries, as well as for industrial water treatment. When pressurised air is not available or not wanted, electromotive valves are ideal. For valves that are operated remotely from the central air supply, the operational costs can be reduced. The superior control characteristics are another benefit of electromotive actuators.
