FUNCTIONAL SCHEMATIC

HIGH FLOW (C V = 1.0) PURGE GAS REGULATOR

The 44-3200 High Flow Regulator is designed as a purge gas TYPICAL APPLICATIONS
regulator and may be used in gas systems involving corrosive
or toxic media. High Flow Purging Systems
The 44-3200 features a large main valve and a flow capacity of Regulating Corrosive Gases and
Cv =1.0. In the high pressure version, the main valve is Specialty Gases
balanced to minimize the effect of inlet pressure fluctuations Manifold Regulator
on outlet pressure. The low pressure version utilizes an Research Labs
unbalanced main valve for reliable shutoff.
All wetted (media contact) parts are 316 Stainless Steel (or
brass), CTFE and Teflon® . The designed maximum leak rate is
2 x10-8 atm cc/sec He.
An adjustable stop may be set to limit outlet pressures that
meet specific system requirements.
