Recently we faced a challenge from our customers to remove the dead leg between the seal points of a typical block and bleed. After painstaking hours of research and development, we’ve created the dead-leg-free ASEPCO Block and Bleed Valve.

Unlike typical valves, this is a block and bleed valve that is machined together to shorten the area between the two valve seats. We’ve applied our contamination-free, radial-diaphragm technology to create a reliable valve that is

easy to assemble and inspect, with no dead leg, and in so doing, we’ve eliminated potential sources of contamination and the extra cleaning time of a typical valve.

We’ve designed hundreds of special valves by customer request. Call us to talk about your special needs.

Valve sizes: 0.5″ compact, 0.75″, 1.0″, and 1.5″
