4022 Regulators

Critical Purity Regulators for Corrosive Service

Single Stage 316 Stainless Steel Barstock Body,
Six-Port Configuration, 316 Stainless Steel
Diaphragm
The 4022 Series regulators are intended for primary pressure
control of critical 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 ■ High purity chamber
chromatography pressurization
■ Ultra high purity carrier gases ■ Liquefied hydrocarbon gas
■ Zero, span, and calibration control
gases ■ Control of cryogenic gases

Features and Benefits
■ 316 Stainless Steel ■ Outlet Pressure Ranges ■ 316 Stainless Steel ■ Pipe Away Relief Valve –
