Marshall MEGR253 LP Dual-Stage Auto-Changeover Propane Regulator
Marshall Excelsior's dual-stage auto-changeover propane regulator is for RVs with dual propane tank hookups. It combines both a high pressure first stage and a low pressure second stage regulator into a single unit. Ideally designed for RV applications, these regulators ensure a smooth and continuous flow of gas to all appliances. Its inlets are 1/4" FPT and the outlet is a 3/8" FPT.
  • Auto-Changeover: Connect two propane tanks to the regulator
  • Low Pressure: Outlet pressure is 11"W.C. (0.5 PSI)
  • Dual Stage: Has integral first and second stages that ensure smoother, more consistent flow
RV Low Pressure
RV appliances require low pressure propane (11"W.C./0.5 PSI) for efficient operation. This regulator has two-stages to achieve low pressure. The first-stage reduces the tank pressure to about 10 PSI. The second-stage reduces the 10 PSI to 11"W.C. (0.5 PSI)
Automatic Changeover
An automatic changeover regulator is designed for use with two propane cylinders. Choose the service (primary) cylinder with the cylinder selector. When the service cylinder empties, the indicator will turn red and engage the reserve (secondary) cylinder.
