NATIONAL TOLL FREE DIRECTORY1-866-574-5100 | ON THE WEBwww.nee.ca REGULATORS DOMESTIC REGULATORS First Stage Regulators First stage regulators are typically used to reduce tank pressure to an intermediate pressure; usually 5 to 10 PSI for further pressure reduction by a second stage regulator located closer to the load. This allows for the use of smaller piping and can contribute to substantial savings. Care must be taken in colder climates to ensure that the pressure setting does not create dew point concerns that could cause the propane vapour to condense back to a liquid resulting in regulator freeze-ups and possible problems at the burner. Fisher First Stage Regulators The R622H First Stage Regulator is constructed of corrosion-resistant and wear-resistant materials, designed to provide a recommended replacement life of 20 years (a 30% improvement over previously existing designs). Features: • 1/8” F NPT pressure taps on the inlet and outlet for easy system pressure checks. • Large 3/4” drip-drip lip vent to reduce vent blockage and freeze-ups. • High capacity internal relief with built-in travel stop providing the best over-pressure protection in the industry. • Superior lock-up performance for precise and consistent performance. • Corrosion-resistant materials and coatings for durability. • Positive draining spring case. • 5 Year Warranty. The R122H Non-Adjustable Regulator features a molded diaphragm, over- sized relief valve & a compact design with excellent capacity and performance for a small first stage regulator.
