Airgas Model N245D350 Brass High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Non-Lubricated Check ValveThis series of two stage, high purity regulators is designed for non corrosive analytical and process applications requiring precise, stable, delivery pressure control. The two stage design yields a delivery pressure of less than 0. 02 100 psi inlet change. These regulators come with a CGA nipple that has a special high purity, non lubricated check valve incorporated into nose and prevents air and contaminants from entering the gas stream during

mildly corrosive and process applications where precise flow control is not critical

and semiconductor processing

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

convoluted Hastelloy diaphragm provides good regulating performance and maximum purity integrity without the need for a soft seal

They are equipped with a CGA-180 connection for easy attachment to Airgas® lecture bottles

A diaphragm packless outlet valve with a 1/4" compression tube fitting is provided for flow control and to maintain system purity

pilot plant and mainte-nance shop applications

These units feature stainless steel diaphragms and bar stockbodies with low internal volume and minimal dead space

This creates consistencies in processes and extends column life in GC applications

a cross purge assembly is required to maintain the warranty and for safety

Made of durable

316 Stainless Steel Diaphragms - provide precise pressure control
