Individual Tank Control with Built-In Ball Valves

Our multi-tank systems are designed for flexibility, convenience, and safe operation.

Each tank is equipped with its own individual ball valve, allowing you to control the flow from each tank independently. This means:

  • Operate All Tanks Together: All tanks can remain open and operate simultaneously as one connected system.
  • Backflow Prevention: Need to take a tank offline? Simply close that tank’s ball valve without having to shut down the entire system. Prevents unwanted reverse flow when operated properly (means shut the ball valve off ;).
  • Balanced System Operation: Ball Valves allow some tanks to be turned off to draw the fuel from the remaining tanks.
  • Storing System: If the portable system was removed and the ball valves are shut off it traps the gas in manifold system- ensuring for a great start the next time!

One System. Individual Control. Added Peace of Mind.

Whether you choose to run all tanks together or isolate an individual tank when needed, the built-in ball valves give you the flexibility and control to manage your system with confidence.

How a First Stage Regulator Works

A first-stage regulator reduces the high pressure from the propane cylinders to an intermediate pressure of 4–6 PSI. This higher pressure allows propane to travel efficiently over longer distances with minimal pressure loss.

A second-stage regulator (sold separately) is then installed closer to your appliance or building. It further reduces the pressure to a usable appliance pressure of approximately 11 inches water column (9–13″ W.C.).

Note: A second-stage regulator is required for most propane appliances and should be installed after the supply line.
