Type R622E, a Two-psi Service Regulator, is designed for Two-psi LP-Gas Regulator Systems and listed by Underwriters Laboratories (UL®). These units are installed downstream from a First-Stage regulator and reduce an inlet pressure of 10 psig to a nominal 2 psig outlet pressure. Two-psi Service Regulators are designed for domestic applications that supply 2 psig LP-Gas to a line regulator located inside the building. In most cases a manifold is used with corrugated stainless steel tubing (CSST) as well as other acceptable piping materials for routing to the line pressure regulator supplying approximately 11 inches w.c. to appliance regulators.
Type R622E Two-psi Service Regulators feature a combination relief valve and large vent that provide overpressure protection and exceed UL requirements. Both units have a stainless steel inlet screen to reduce the amount of debris from entering them. Fisher® brand Types R622E and R652E are painted green with a white closing cap for easy identifi cation and have a temperature rating of -20 to 160°F, but have passed Fisher internal testing for lockup, relief start-to-discharge and reseal down to -40°F.
Type R622E – Time proven design constructed of corrosion resistant materials, the Type R622E is designed to provide a recommended replacement life of 20 years. Fisher brand’s fabricreinforced diaphragm and large diaphragm area provide accurate regulation at increased capacities. All components provide superior resistance to fi eld conditions that may cause wear and corrosion. Built-in 1/8-inch taps (orifi ced to a number 54-drill size) on the upstream and downstream sides allow for easy gas system checks.
