Designed for use in domestic applications, the R122H’s size makes it perfect for tight installations. Its non-adjustable setpoint makes the unit virtually tamper proof. The outlet pressure setpoint remains at a nominal factory setting of 10 psig. Type R222H regulator has all the benefits of the full size R622H benefits, but with a compact profile. 65% greater flow than typical compact regulators but with a 40% smaller footprint. Both of these compact first stage regulators are perfect for underground tanks or limited dome spaces.

Time proven design constructed of corrosion-resistant and wear-resistant materials,built-in 1/8" FNPT gauge taps on both the inlet and outlet pressure sides allow for easy system checks. A large 3/4" FNPT drip-lip vent reduces the chance of blockage by freezing rain or sleet when properly installed with the vent pointing down. Each R622H is equipped for overpressure protection with a corrosion-resistant internal relief valve that provides high capacity relief and a travel stop on the closing cap.
