Airgas Model N245D660 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

and semiconductor processing

which provides increased safety and reliability at high delivery pressures

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

CR-80 Repel is one of the few non-aluminized

These 316 stainless steel single-stage high-purity regulators are recommended for non-corrosive analytical

These single-stage regulators are designed for mildly corrosive gases that attack brass or copper-bearing alloys

A preset safety relief valve makes these regulators suitable for use only with non-corrosive gases

Two 10 x 32 UNF-threaded holes in the body allow for bracket or external panel mounting

nylon-reinforced neoprene diaphragm

andnon-corrosive gas mixtures for analytical instrumentation

stainless steel diaphragm with metal to metal seals provides good regulating performance and maximum purity integrity without the need for a soft seal

Note: Due to the corrosive nature of the gases used with this regulator
