Working
UL/FM approved valves operate based on specific design principles and mechanisms to ensure safety and reliability, especially in fire protection systems. When opened, the valve allows water to flow freely; when closed, it stops the flow to prevent leaks or system pressure loss. It ensures that water flows in one direction only, preventing backflow which could compromise system integrity.
