Bürkert ON/OFF Control Tops

Bürkert ON/OFF control tops bring pneumatic valve control, position feedback, diagnostics, and communication directly to the valve. Types 8682, 8683, and 8691 provide flexible automation options for hygienic process valves, helping simplify commissioning, improve visibility, and standardize valve automation across your process.

Key Features

  • Integrated Valve Automation: Combines pneumatic control, valve position monitoring, feedback, and communication in a compact device mounted directly on the valve.
  • Clear Status Indication: Color-coded LEDs provide at-a-glance visibility of valve position, operating status, and diagnostic conditions.
  • Simplified Commissioning: Automatic teach functions help detect and store valve positions with less manual setup.
  • Flexible Communication: Available options include 24 V, AS-Interface, IO-Link, and additional communication options depending on the model.
  • Designed for Hygienic Processing: Cleanable, durable construction supports food, beverage, pharmaceutical, biotech, and other hygienic applications.

Frequently Asked Questions

An ON/OFF control top automates the opening and closing of a pneumatically actuated valve while also monitoring and reporting its position. Bürkert control tops can combine pneumatic control, position feedback, status indication, diagnostics, and communication directly at the valve.

The primary difference is the complexity of the valves they can automate. Type 8682 is designed for butterfly, ball, and single-seat valves. Type 8683 supports those valve types as well as double-seat valves and multi-position actuators requiring additional pilot valves. Type 8683 also offers additional functionality such as configurable cleaning features and more advanced valve control and diagnostics.

The Type 8691 is designed primarily for Bürkert ELEMENT Type 21xx pneumatic process valves, including Types 2100, 2101, 2103, 2104, 2105, and 2106. Adaptation to certain third-party pneumatic actuators is also available depending on the valve and application.

Yes. Types 8682 and 8683 are designed to work with compatible hygienic process valves from different manufacturers using the appropriate Bürkert adapter. The correct control top and adapter should be selected based on the valve type, actuator, and automation requirements.

Bürkert control tops use valve position sensing along with color-coded LED indication to provide visual feedback directly at the valve. Depending on the model and configuration, valve position and diagnostic information can also be communicated back to the plant control system.

Selection depends on the valve type, actuator configuration, number of valve positions, communication requirements, and existing automation platform. In general:

  • Type 8682: Butterfly, ball, and single-seat valves
  • Type 8683: Butterfly, ball, single-seat, double-seat, and more complex multi-position valves
  • Type 8691: Bürkert ELEMENT Type 21xx process valves

Oliver M. Dean can help evaluate your existing valve and automation requirements and identify the appropriate control top, adapter, and configuration.
