What is the difference between double-acting and single-acting REVO actuators?

Double-acting actuators use compressed air for both opening and closing strokes. Single-acting models use air in one direction and spring force in the opposite direction, providing fail-safe operation (spring-return to a safe position) if air supply is lost.

What flange standards do REVO actuators comply with?

REVO actuators comply with DIN/ISO 5211 and DIN 3337 (female square) flange standards. NAMUR and ISO interfaces are also provided for accessory mounting.

Overview

The Crane REVO Series R pneumatic quarter-turn actuators are engineered for reliable automation of 90° rotary valves including ball valves, plug valves, and butterfly valves. These actuators are widely deployed across process industries where precise valve control and fail-safe operation are critical requirements.

Available in both double-acting and single-acting configurations, REVO actuators offer flexible control options. Double-acting models use compressed air for both opening and closing, while single-acting versions employ spring return for fail-safe operation during air supply failure. This makes them suitable for both standard open/close duties and modulating control service.

REVO actuators are manufactured to comply with EN, ISO, and DIN standards, with NAMUR and ISO-compliant interfaces for seamless integration with solenoid valves, limit switches, and positioners. The actuators can also be configured for 180° or multi-position applications as required.
