Airgas Model N245D590 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

Optional 15 Ra electropolished with faceseal

Since this regulator is dome loaded by a remote sensing pilot regulator

These models feature encapsulated filter assemblies to protect the valve seat from contamination

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

Captured bonnet ports with optional vent adapters are standard on both stages and allow the venting of hazardous gases in the event of diaphragm failure

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

Nickel plating of the interal gas path surfaces makes it an excellent choice for analytical applications

The two-stage design yields a delivery pressure change of less than 0
