Cavagna RV Propane Regulator 924N — Dual‑cylinder Auto Changeover, 160,000 BTU, Adjustable Pressure

The Cavagna Kosan 924N RV propane regulator is an automatic two-cylinder changeover valve that maintains uninterrupted gas flow to RV appliances and shows full/empty status from the top for easy checks.

Designed for travel trailers and motorhomes with a two-tank setup, the 924N combines a two-stage regulator with an automatic switching mechanism so you can swap an empty cylinder without shutting down your propane supply. Built of durable materials and rated to handle up to 160,000 BTU, it fits common RV plumbing with 1/4" inverted flare inlets and a 3/8" female NPT outlet, and includes an RV-style L bracket for quick mounting.

How does this regulator keep my RV appliances running without interruption?

The Kosan 924N senses when the service cylinder is depleted and instantly switches to the reserve cylinder so burners, heaters, and other gas devices stay lit. This automatic changeover prevents service interruptions while you remove the empty tank for refill.

• Automatic two-cylinder switching for continuous gas supply
• Visible full/empty indicator accessible from above through most tank covers
• Up to 160,000 BTU capacity suitable for multiple onboard appliances
• Maintains steady working pressure for reliable flame performance

What connections, pressure range, and materials does the 924N use?

The unit installs with two 1/4" inverted flare inlets and a 3/8" female NPT outlet to match common RV fittings. It delivers stable regulated pressure and uses corrosion-resistant fasteners plus a high-temperature diaphragm to hold up in typical RV environments.

How easy is installation and inspection with this regulator?
