Description
The Watts LF530-C is a 1/2″ lead-free relief valve engineered to deliver dependable overpressure protection in residential and light commercial hydronic heating and plumbing systems. Built to Watts’ exacting quality standards, this valve features a lead-free bronze body construction that meets stringent low-lead compliance requirements — making it a code-compliant choice for potable water and closed-loop hydronic applications.
With a set pressure of 50 PSI and a maximum working pressure rating of 175 PSI, the LF530-C provides a wide operating range suited to boiler systems, water heaters, and pressure-sensitive piping networks. When system pressure exceeds the set point, the valve opens automatically to discharge excess pressure, protecting equipment and piping from damage caused by overpressure events.
