High Purity Economical Regulators

Single Stage Chrome-Plated, Five-Port
Configuration, 316L Stainless Steel Diaphragm
The 2002 Series regulators are intended for primary pressure control
of non-corrosive, high purity or liquefied gases. It is recommended
for applications where minor fluctuations in outlet pressure due to
diminishing inlet supply pressure can be tolerated.

Typical Applications
■ Gas supply purging ■ Calibration gas control
■ Gas system charging ■ Atomic absorption acetylene
■ Fuel gas supply control
