Airgas Model N245B590 Brass High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Non-Lubricated Check Valve Two Stage Type 316 stainless steel internal

Type 316 stainless steel internal components are ultra-sonically cleaned and electropolished to a 32-Ra surface finish for applications where a contamination-free flow stream is critical

The metal-to-metal diaphragm seal prevents contamination by eliminating the need for a soft seal and provides a leak-rate design of less than 2 x 10–8 ccs helium

an integral line regulator is used to maintain constant downstream pressure

Specially designed for acetylene service

Airgas Model N245B590 Brass High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Non-Lubricated Check Valve Two Stage Type 316 stainless steel internalThis 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
