In modern fire protection systems, controlling water flow efficiently and reliably is critical. Doing so relies on a multitude of components, switches and valves internally working together to provide optimal water flow and pressure.
Butterfly valves have emerged as an integral component in these systems, offering a perfect balance of simplicity, reliability, and cost-effectiveness. These essential devices play a vital role in controlling water flow through fire standpipe and fire sprinkler systems, providing both isolation and regulation capabilities.
How Do Butterfly Valves Work?
At their core, butterfly valves operate on a remarkably straightforward principle. They control water flow through the rotation of an internal disc, which can be positioned parallel to the flow for full water passage or rotated 90 degrees to completely stop the flow.
This unique design allows for quick operation while maintaining sprinkler system integrity, making them ideal for fire protection applications.
