The vinyl-coated three-position steel handle provides at-a-glance control and monitoring of valve status, all on a compact, forged-brass body.

Suitable for use in water-based systems including fire protection, the 1" (25.4 mm) Test and Drain Valve assembly features a PTFE seat and chrome-plated brass ball that form a water-tight seal when not in operation.
