The New Generation of Butterfly Valves

Innovative Design


The lower overall height and reduced weight make the PR actuators quick and easy to install. The patent-pending self-adjusting end stop algorithm ensures zero leakage at 200 psi close-off. The PR actuator is also available with integrated electronic fail-safe technology in a NEMA 4 enclosure.

Proven Reliability


The patented brushless direct current motor technology reduces energy consumption by up to 80% and ensures longevity and optimal system performance. Unique electronics, software, and available super capacitor technology not only enables user selection of fail position (0-100%) but also delays unnecessary actuator movements during short brown out conditions; avoiding changes in the HVAC and building automation system.
