Description

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 2-inch (50 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.

Features

Multi-Functional Space Saver: Compact, single-valve architecture merges the operational utilities of both an inspector’s test station and a primary drain line, saving space and installation labor.
Tri-Position Operational Logic: Outfitted with a heavy-duty vinyl-gripped steel lever providing positive detent alignment for secure Off, calibrated flow Test, and unrestricted system Drain steps.
Integrated Inspection Window: Includes a rugged, pre-installed structural sight glass that lets maintenance technicians safely verify real-time line discharge and air clearing.
Calibrated Internal Orifice: Integrated with an internal tamper-resistant flow orifice calibrated to match standard sprinkler K-factor discharging for highly accurate waterflow switch tests.
Corrosion-Resistant Integrity: The combination of an ASTM C85700 forged brass body, chrome-plated internals, and low-friction TFM seats guarantees complete freedom from rust-binding over long idle intervals.
