Precise, reliable performance. Lasting value. Ease
of installation. Everything you look for in direct-
coupled actuators hinges on quality. And quality
engineering is what makes Honeywell’s complete
line of actuators the top performers in the industry.
Our global engineering team designs and tests
our direct-coupled actuators to exceed rigorous
global standards — and to meet Honeywell’s own
demanding life testing.
But we don’t stop there. Thanks to our continuous
improvement process, Honeywell actuators are now
easier than ever to install. You’ll also benefit from
consistent wiring regardless of signal type, common
accessories and a simplified selection process.
Honeywell’s complete line of building control
products, including valves and actuators, are
already proven in more than three million buildings
worldwide. So when you need spring or non-
spring return actuators for your damper and valve
applications, specify Honeywell. We make precision
easy.
