Shield SD-TDV50T Threaded Test and Drain Valve 1?” (40 mm)

The Shield SD-TDV50T is an industrial-grade, single-handle test and drain ball valve assembly designed for permanent installation in wet pipe fire sprinkler systems. Forged from high-strength brass with a chrome-plated ball and resilient PTFE (TFM) seats, this 1?-inch (40 mm) component replaces complex multi-valve bypass configurations. It features a three-position handle (Off, Test, Drain) that directs fluid to a tamper-resistant interior test orifice to simulate sprinkler activation, or opens fully for a high-volume system express drain. Compliant with NFPA 13, 13R, and 13D criteria, the valve body incorporates a built-in sight glass for seamless visual inspection of flow dynamics and is rated for a safe working pressure of up to 300 PSI.
