ASEPCO Zero Dead Leg Valves are used in situations where sampling, draining, transferring, or diverting process fluid from a line is necessary. Zero Dead Leg Valves are designed to minimize hold-up in point-of-use applications. Our design completely eliminates any dead leg. In addition, the diaphragm seats flush to the inside diameter of the piping.
Valve sizes: 0.5″, 1.0″, 1.5″, 2.0″, and 3.0″
