We’ve applied our contamination-free, radial-diaphragm technology and easy-to-use clamp assembly to an inline valve configuration, creating a reliable valve that is easy to assemble and inspect. Our customers tell us that this valve is reducing maintenance costs up to 80% and that the design significantly reduces downtime when

changing diaphragms. It never needs adjusting or re-tightening. We’ve designed hundreds of special valves by customer request. Call us to talk about your special needs.

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