« Return To The Gas Regulators List

Combination piston first stage and stainless steel diaphragm second stage offer a high degree of accuracy and control without adjusting the delivery pressure as the supply pressure decreases.

Designed for use with low ppm corrosive gases and gas mixtures where high purity, low flow rates, and stable delivery pressure must be maintained. It's small size fits easily into tight spaces. Low dead volume.
