Double Union Three-Way Pneumatic Diaphragm Valve DBP

The DBP series interconnected diaphragm valve combines two DLP or DHP 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.
