Description
The Watts LF5300A 1/2″ Bypass Relief Valve Compact Poppet-Type 10-250 PSI is installed in piping systems to regulate pressure by diverting excess flow when set limits are exceeded. It is commonly used in heating and cooling circuits, including boilers, water heaters, and other HVAC systems, to maintain stable operating pressures. The valve operates by opening when system pressure rises above its rated range, allowing fluid to bypass and return to the supply or a designated line. Within an HVAC system, it operates as a pressure control component that Support manage flow and supports consistent system operation.
