4032 Regulators

Critical Purity Regulators for Corrosive Service

Dual Stage 316 Stainless Steel
Barstock Body, Six- Port Configuration,
316 Stainless Steel Diaphragm
The 4032 Series regulators are intended for primary pressure
control of critical purity and corrosive gases. It is recommended
for applications requiring constant delivery pressure control,
regardless of supply pressure.

Typical Applications
■ EPA Protocol gases ■ High purity chamber
■ Gas and liquid chromatography pressurization
FID, GC, HID, PID, FPO, RD, ■ Petro/Chemical Industry
ECD ■ Purge gases
■ Ultra high purity carrier gases ■ Laboratory analysis
■ Zero, span, and calibration
gases
