Air System Products BVD-2S12 Ball Valve Drain

Air System Products BVD-2S12 Ball Valve Drain is a 1/2-inch NPT stainless steel valve drain with a built-in solid-state timer that automatically vents condensate (oil and water) from compressed air systems. This non-clogging, full-port drain provides a straight-through flow and uses a rugged seat-and-seal design for long service life, plus a test button to verify operation. The stainless variant (2S12) is rated up to 2,000 PSI and is housed in a NEMA 4X enclosure, suiting harsh environments. Connections are 1/2" NPT, making it easy to integrate with standard piping. The timer is adjustable, enabling you to set the drain cycle frequency to match your condensate load. Ideal for drains on filters, air dryers, separators, receivers, and aftercoolers to remove moisture and oil carryover from compressed air systems. The BVD family also includes bronze versions (2B12) rated to 600 PSI and other size options such as 2S10 (1"), 2S14 (3/4"), and 2S34 (1"), giving you versatility across a range of pressures and configurations.
