Neon Controls - Series 20 High Flow Regulator

Designed for applications with low inlet pressures or higher flows, the Series 20 can handle inlet pressures as high as 6000 psig. Even with large changes of flow, the regulator can closely hold to its set outlet pressure, making this regulator a good choice as a primary regulator feeding another downstream regulator.

When used with optional low Cv values the Series 20 becomes a super-sensitive regulator, where the high diaphragm to Cv ratio gives excellent control, even to very low pressures in inches of water column.

Designed to offer many choices to match your specific needs, the Series 20 is available in different body materials, Cv values, porting options, and seat materials.
