Manifold Assemblies 15 Following are three examples of machines where manifold assemblies designed by Norgren solved specific problems. Leveling Valve Manifold A transportation application required valves that could inflate or exhaust bags in an air suspension system to raise and lower a vehicle quickly and smoothly. Norgren designed an assembly using an aluminum block manifold with three Nugget 200 spool valves operated by solenoid valves. The Nugget 200 has a proven track record in commercial vehicles and rail applications over several years and the solenoids were chosen for their reliability in challenging operating environments. A design change added the requirement to stabilize the vehicle when cornering. Norgren was able to expand the existing aluminum block manifold slightly to increase the number of valves from three to five to meet this new demand. By using a manifold instead of individual valves, we eliminated the need for individual piping, simplifying installation and maintenance while improving reliability Portable Ventilator/ Respiratory Therapy Device The Norgren assembly integrated an accumulator, valves, pressure transducers, a custom outlet block and a built-in filter assembly. This manifold assembly was created to fit into an unusually slim housing. Integrating the accumulator and filter allowed the assembly to fit the small footprint and also reduced weight – a key requirement in portable equipment. The valves and manifold were delivered as a single-source turnkey assembly, simplifying acquisition for the customer. DNA Analysis System In this lab-on-chip application, the OEM needed to move small samples and multiple reagents at high speeds with high reliability. Norgren recommended an acrylic manifold because of the complexity of air channels routed to multiple locations. An acrylic laminated manifold allowed us to deliver a complicated but compact structure at a reasonable cost. The four-layer laser-bonded manifold holds nearly 60 valves, each meeting different requirements for speed, longevity and salt and moisture resistance depending on their function. The manifold had to be designed to mate with a chip, so dimensional stability was critical. Find out more norgren.com We translate your blueprint to brilliance in manifold subassemblies
