Double Union Three-Way Manual Diaphragm Valve DBM

Double Union Three-Way Manual Diaphragm Valve (DBM)

The DBM series interconnected diaphragm valve combines two LDM or HDM series ultra-pure diaphragm valves (double union) into a single unit. By sharing the piping flow path, it minimizes dead zones while maintaining excellent degassing characteristics. The interconnected diaphragm valve inherits the fundamental performance of the original valves and, through the combination of similar or different types, enables the design of more compact piping systems, significantly saving space.
