Airgas Model N245A320 Brass High Purity Single Stage Pressure Regulator With 1/4” FNPT Connection And Non-Lubricated Check ValveThese brass, single stage, high purity regulators are recommended for non corrosive analytical and process applications where precise flow control is not critical. A specially designed, convoluted, stainless steel diaphragm with metal to metal seals provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. These regulators come with a CGA nipple that has a special

and semiconductor processing

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

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

A needle valve is included on the outlet

04/100 psi inlet change

The optional bonnet vent adapter allows for the venting of hazardous gases in the event of diaphragm failure

allows the exterior surfaces to maintaina good appearance in outdoor environments

along with the composite bonnets

Airgas®’ unique line of Cyclone Technology pressure regulators are designed to preserve the specific gas mixture

provides precise pressure control from full cylinder to almost empty

this regulator body has minimal internal volume - there are no large cavities and pockets associated with forged-body regulators
