Butterfly valves
Explore our full range of butterfly valves for HVAC systems
IACS carries all of the major butterfly valve brands, including Belimo and Siemens.
A butterfly valve is a type of valve that controls or isolates fluid flow. A rotating disc serves as the closing mechanism. IACS's technical staff is available to help you.
How a butterfly valve works
The butterfly valve's disc is positioned at the pipe's centre. A rod runs through the disc and connects to an actuator on the valve's outside. The disc is turned parallel or perpendicular to the flow by rotating the actuator. Visit our IACS blog article on all types of valves for additional information.

Butterfly Valves for HVAC and Industrial Control
Shop all Butterfly Valves at iACS. A butterfly valve operates using a rotating disc to regulate flow, making it ideal for systems where space is at a premium but high performance is required. These valves are frequently utilised in large-scale HVAC setups to manage water flow with precision. Understanding how these components integrate into broader infrastructure is vital; for instance, you can learn more about how the valve works in the AHU systems and HVAC control valves to optimise your installation.
