Double Acting Pneumatic Actuator HP88D

Part of the trusted HP series rack and pinion line, the HP88D is built for industrial environments where reliable, high speed valve control is non negotiable. Designed to automatically open and close 90° quarter turn valves,- including ball, butterfly, and plug valves,- it uses compressed air in both directions for precise, responsive actuation every time.

Unlike spring return alternatives, the double acting mechanism eliminates the risk of spring fatigue, making it the preferred choice for applications that demand fast and frequent cycling over extended periods. Its multi-standard ISO 5211 bottom mounting flange and 17 mm star/square drive output shaft ensure compatibility across a wide range of valve sizes and stems, reducing the need for costly custom fittings.

Built to perform in the harshest conditions, the HP88D is frequently certified to ATEX standards, making it suitable for safe operation in explosive atmospheres and demanding industrial zones. From processing pipelines to chemical plants, it delivers the consistency and durability that critical infrastructure requires.
