R966 Series Automatic Changeover Regulators
The R966 Series is a Underwriters Laboratories listed regulator widely used on motor homes, recreational vehicles and domestic installations because they maintain reliable, uninterrupted service. Available with a variety of pigtails and mounting brackets, the R966 has a built-in indicator to display when the changeover is made. Remote visual indication is available for all R966s by using Type 803. Gas is withdrawn from the supply cylinder until pressure is reduced to approximately 6 psig (0,41 bar). A spring then forces the cam downward, opening the other First-Stage inlet fitting and allowing gas to enter the R966 from the reserve cylinder. When the changeover (from supply to reserve cylinder) is made, the cam activates a red warning flag in the built-in indicator window to show that the original supply cylinder is empty. The arrow on the changeover knob can then be moved so that it points to the new supply cylinder. The empty cylinder can now be refilled, becoming the reserve cylinder.
All R966s have the 3/4" FNPT drip-lip vent, making additional protection of the vent unnecessary except on mobile applications where road splatter could block the vent. High capacity internal relief construction keeps appliance pressure at 2 psig (0,14 bar) or below. An extension on the closing cap acts as a travel stop to open the internal relief valve under emergency conditions.
