4005 Regulators

Critical Purity Regulators for Non-Corrosive Service

Line Regulator, Single Stage Brass
Barstock Body, Four-Port Configuration,
316 Stainless Steel Diaphragm
The 4005 Series regulators are intended for secondary pressure
control of non corrosive, critical purity or liquefied gases. It is
recommended as point of use pressure control in critical purity
gas delivery systems.

Typical Applications
■ Bulk gas delivery systems ■ High purity chamber
■ Gas and liquid chromatography pressurization
■ Ultra high purity carrier gases ■ Liquefied hydrocarbon gas
■ Zero, span, and calibration control
gases ■ Control of cryogenic gases
