Introduction:
 The R522H Series First-Stage regulators are designed for use as the first regulator of a Two-Stage regulation system on domestic applications. This unit features the latest design in regulator technology and is constructed using corrosion-resistant and wear-resistant materials.
A large 3/4-inch FNPT drip lip-vent reduces the chance of blockage by freezing rain or sleet when properly installed with the vent pointing down. The overall 6.1-inch (155 mm) profile makes the R522H Series ideal for under-thedome installations.
