Five-port, bare brass barstock, point-of-use regulator for ultra-high purity inert gas applications
The CONCOA 435 Series regulator is intended for secondary pressure control of
ultra-high purity inert gases, including non-corrosive and liquefied
gases. Unlike most pipeline equipment, the 435 Series regulator is rated
to full cylinder pressure, making it ideal for point-of-use pressure
control in high purity gas distribution systems. The bare brass body
eliminates contamination from chromium or nickel and ensures no
confusion with stainless steel in mixed material environments.
