How do I find the right actuator for my valve?

If you have a Siral valve body, you can navigate to its product detail page, which features an 'Actuator Selection' tab listing all compatible actuators. For more complex needs, our Product Finder and Valve Sizing Calculator on the Support page are excellent tools to help you specify the correct components for your application.

Can I get a quote for multiple products at once?

Are technical documents like submittals and datasheets available for all products?

Yes, we strive to provide comprehensive documentation for our entire catalog. On each product's detail page, you will find a 'Downloads' tab containing links to submittal sheets, valve and actuator datasheets, and installation manuals where applicable. You can download these individually or as a combined .zip file.

What does 'fail-safe' mean for an actuator?

A fail-safe actuator is designed to automatically return to a predefined 'safe' position (either open or closed) upon loss of power. This is typically achieved with a mechanical spring-return mechanism and is a critical safety feature for applications like fire and smoke dampers or systems where a specific state must be maintained during a power outage.
