435 Series Regulator

Five-port, bare brass barstock, point-of-use regulator for ultra-high purity inert gas applications
4353021-01-000 shown

The 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.
