3032 Regulators

High Purity Regulators for Corrosive Service

Dual Stage 316 Stainless Steel Barstock Body,
Four-Port Configuration, 316 Stainless Steel
Diaphragm
The 3032 Series regulators are intended for primary pressure
control of high 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
