The body is constructed from lead-free brass (wetted surface lead content \u0026lt;0.25% by weight, compliant with NSF 61\/372 and California AB1953), rated for 150 PSI working pressure and temperatures up to 140°F (60°C). The QT suffix denotes quarter-turn OS\u0026amp;Y-style ball valve shutoffs (green lever handles visible in photos), the S suffix denotes an integral Y-type inlet strainer, and the FS suffix denotes a flood sensor port with a pre-installed Smart and Connected flood sensor (visible as the black solenoid-style fitting on the relief valve outlet in photos). This assembly is designed for potable water service, irrigation systems, boiler make-up water, and any cross-connection control application requiring RP-level protection per local plumbing codes.
