PR 190 Aluminum Single-Stage Multi-Flow Regulator

These aluminum single stage piston type regulators are recommended for High Purity, non-corrosive application where slight variance in delivery pressure is acceptable as inlet pressure decreases.

This regulator has eight flow settings ranging from 0.2 to 6.0 liters per minute. The increments are listed below.

Ideal applications include pure gases and low level corrosive mixtures such as nitric oxide, sulfur dioxide in nitrogen and other emission mixtures.
