Item Details
The complete stainless steel construction of these regulators allows for the high-purity design to function in the most severe environments. Harsh corrosive environments which have high levels of sea salt, fluorides, unnaturally occurring chlorides, sulfides or other acidic/caustic elements in the ambient atmosphere will cause premature degradation of brass and most vinyl plastics. The near bullet-proof design of the Airgas® Severe Duty Regulator provides exact pressure regulation while resisting the negative effects of a corrosive environment. These regulators also have a check valve CGA-that prevents contaminants from entering the gas stream during cylinder change out. The internal threadless seat design of these single and two-stage stainless steel regulators is the same as used in our high-purity Y11-C444 and Y12-C445 series. The convoluted Hastelloy® C-22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging. A 1/4-turn packless diaphragm outlet valve with a 1/4" compression fitting is provided to maintain optimum system purity. Captured bonnet vent ports are plugged with sintered mufflers which minimize the negative corrosive effects on the control spring assemblies. The regulator bodies are ultrasonically cleaned for the most demanding high-purity service.Features
