Diaphragm Regulators Miniature Tied

RTCC Series

Introduction Diaphragm Regulators Miniature Tied

Diaphragm Regulators Miniature Tied RTCC Series feature a single-stage pressure reduction design. Their tied diaphragm construction provides positive shutoff. With no threads or springs in wetted areas and a compact form, these regulators are ideal for low flow ultra-high purity applications.
