Pneumatic Control Unit Top Actuator

The Pneumatic Control Unit Top Actuator is an automation accessory mounted on top of a 210X-series pneumatic process valve actuator. Manufactured by Bürkert, typically as a Type 8690 or 8697, it controls the valve actuator and delivers reliable position indication throughout the process cycle.

Fitted to a 210X actuator, the unit manages pneumatic actuation of process valves, provides open and closed position feedback, and handles solenoid pilot control. It integrates directly into plant automation systems such as PLC or DCS setups, giving operators clear oversight of valve status and precise control across the line.

Construction combines an engineering thermoplastic housing with a transparent polycarbonate cover, allowing position status to be read at a glance. Stainless steel fasteners and pneumatic fittings, along with the internal electronic and pneumatic components, keep the unit dependable in demanding process environments. The polymer housing withstands moisture and washdown conditions, making it well suited to clean and hygienic systems.

The unit fits a range of Bürkert ELEMENT process valves, including 2100 angle-seat valves and 2103 diaphragm valves, giving plant engineers flexibility across different valve types on a single automation standard. Environmental protection to IP65 and IP67 keeps out dust and water in wet or dusty locations, while ATEX and IECEx versions cover hazardous area installations. RoHS compliance and an EU Declaration of Conformity support use across regulated industries.
