Mar 22, 2013 Designed to resist gas impurities, Fisher® Types R232A, R632A, and RS232E accept 250 psig inlet pressure and reduce pressure across two pressure drops, resulting in final pressure of 2 psig. Units combine both first and second stages into one unit for installation on tight fit applications. Regulators not only pass Emerson test specifications for operation at -40°F, but also operate reliably at -40°F after being exposed to environment simulating significant propane contamination.
