MEC Excela-Flo integral two-stage regulators combine the first and second stage regulator set-up into one convenient unit converting tank pressure to 2 PSI. All MEC integral two-stage 2 PSI regulators are white indicating 2 PSI outlet pressure. Integral two-stage 2 PSI regulators are recommended for installations with short piping distances, but provide the same advantages of two-stage regulation with a single unit. 2 PSI service regulators are used in conjunction with an LPG line regulator either at the indoor appliance or a remote manifold distribution header inlet. All MEC integral two-stage regulator vent have tapped ports (7/16 -24 – First Stage) (3/8” FNPT or 3/4” FNPT – Second Stage) and our exclusive E-Z Grip screens located over the outlet. Both the MEGR-1232E and MEGR1632E series offer optimal relief performance that well exceeds UL test requirements providing over pressure protection of no more than 4 PSI downstream pressure. MEC Excela-Flo integral two-stage domesƟ c regulators feature a 25 year recommended replacement life, our exclusive Tri-TapTM (tank, 10 PSI, 2 PSI) pressure port system and tear away leak check adhesive sticker.

**To maximize the lifespan of the regulator, it must be installed above the liquid level of propane: directly connect to service valve, or wall mount above the propane cylinder(s).

Types R622E and R652E, Two-psi Service Regulators, are 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 / 0.69 bar to a nominal 2 psig / 0.14 bar outlet pressure. Two-psi Service Regulators are designed for domestic applications that supply 2 psig / 0.14 bar 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. / 27 mbar to appliance regulators. Types R622E and R652E 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 identification and have a temperature rating of -20 to 160ºF / -29 to 71ºC, but have passed Fisher internal testing for lockup, relief start-to-discharge and reseal down to -40ºF / -40ºC.

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 fabric reinforced 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 (orificed to a number 54-drill size) on the
upstream and downstream sides allow for easy gas system checks.

Type R652E

Provides the same features as the Type R622E, includes a 20-year recommended replacement life with a back mount design.
