Airgas Model N140FHF Brass Specialty High Purity High Flow Pressure Regulator With 1/2" FNPT ConnectionThis series of regulators is used for applications requiring high gas flow rates and a compact design. These regulators can handle flows up to 250 liters per minute of nitrogen with only a 5 psig pressure drop. In addition, these units will handle hydrogen flow up to 1,000 liters per minute without the resonance problems associated with other regulators in this same application.

long-lasting forged brass and then chrome plated

Convoluted Hastelloy® C-22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging

A preset safety relief valve makes these regulators suitable for use only with noncorrosive gases

This two-stage regulator is recommended for use with non-corrosive gases in applications where an ultra-low delivery pressure is required

which decreases internal volume and eliminates the large cavities and pockets associated with forged-body regulators

The needle valve model hasthe valve built into the regulator body reducing the gas path

Bar Stock Bodyprovides low internal volume

delivery pressure control

single-stage regulators is recommended for non-corrosive analytical and process applications

These regulators are constructed of aluminum alloy and are equipped with stainless steel gauges

It maintains an accurate delivery pressure over the life of the cylinder
