Solenoid Valve Kit 120VAC 290 P.S.I. SW290-KIT

The Solenoid Valve Kit 120VAC 290 P.S.I. (part# SW290-KIT) is a genuine Tacony OEM replacement part from the chassis assembly of the Tornado Marathon SE 900 self-contained carpet extractor. It is the electrically operated valve assembly that opens and closes solution flow on command from the machine controls.

What the Solenoid Valve Kit 120VAC 290 P.S.I. does

The solenoid valve is what turns the trigger or switch into actual flow at the jets. A coil pulls a plunger off its seat, solution passes, and the moment power is removed the valve has to close fully or the machine keeps spraying when nobody asked it to. Both the voltage and the pressure rating are part of that: an underrated valve will not seat against pump pressure, and the wrong coil voltage either will not lift the plunger or cooks itself trying.

When to replace the Solenoid Valve Kit 120VAC 290 P.S.I. (SW290-KIT)

Replace it when the valve will not open, will not shut off cleanly, or buzzes and drops out under pressure. Solution that keeps flowing after the switch is released, or jets that dribble between passes, are the classic signs, as is a coil that is too hot to hold.

Solenoid Valve Kit SW290-KIT — fitment and installation notes

Fit it with the flow arrow pointing the right way, and use the seals supplied in the kit rather than the old ones. Work with the machine unplugged and the system depressurised, support the fitting body while tightening so the valve is not twisted against its plumbing, and check for both leaks and clean shut-off before the machine goes back to work. Tacony builds the Tornado Marathon SE 900 and the Powr-Flite Prowler PFX900S on a single machine platform, so this component carries across both brands rather than belonging to either one. It is a shared Tacony component and may fit additional models beyond those listed — call us and we will confirm against your serial number.
