3022 Regulators

High Purity Regulators for Corrosive Service

Single Stage 316 Stainless Steel Barstock Body,
Four-Port Configuration, 316 Stainless Steel
Diaphragm
The 3022 Series regulators are intended for primary pressure
control of high purity and corrosive gases. It is recommended for
applications where minor fluctuations in outlet pressure due to
diminishing inlet supply can be tolerated.

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

Features and Benefits
■ 316 Stainless Steel ■ Front and Rear Panel ■ Outlet Pressure Ranges ■ Low Wetted Volume
Barstock Body Mountable 0-15 to 0-500 psig Minimal purge requirements
Enhanced corrosion Versatile system configuration Broad range of applications
resistance Rear mount 10-32 UNF (2) ■ Convoluted diaphragm
■ 316L Stainless Steel Smooth pressure transition
■ 10 Micron Filtration Diaphragm
Failsafe seat performance No inboard diffusion
