The Multiquip 43140-49 is a genuine OEM 12V LPG Shutoff Valve with Filter designed for STXDF series ride-on power trowels. As a direct OEM component, it is manufactured to the exact specifications required for proper fuel system operation on dual-fuel STXDF machines running on propane. Sourced directly through authorized Multiquip supply channels, this part ensures you are installing the correct valve assembly the first time. DHS Equipment stocks this genuine OEM replacement so you can get your trowel back to work without guesswork on compatibility.
Key Features
- Genuine OEM Electrical Specification: — Rated at 12V DC to match the STXDF electrical system exactly, ensuring the solenoid opens and closes the propane supply at the correct voltage without risk of coil burnout or sluggish actuation.
- Integrated Inlet Filter: — The built-in filter element screens particulates from the LPG supply before they reach downstream fuel components, protecting carburetors and regulators from contamination.
- Direct-Fit for STXDF Trowels: — Engineered as a drop-in replacement for the STXDF super-sized hydrostatic ride-on trowel series, matching the original mounting configuration and fuel line connections.
- Critical Fuel Control Function: — Controls propane flow to the engine on demand; a failed or leaking shutoff valve can cause hard starts, uncontrolled fuel flow, or the inability to run the machine on LPG at all.
- Fuel System Safety Component: — A correctly functioning LPG shutoff valve is essential for safe propane operation — preventing unintended gas flow when the engine is off and maintaining operator and site safety.
The 12V LPG Shutoff Valve with Filter is an electrically actuated solenoid valve that controls the flow of liquid propane gas to the engine on dual-fuel equipment. When the machine is running, the 12V signal from the ignition circuit energizes the solenoid coil, opening the valve to allow propane to reach the fuel system. When power is cut — whether by shutting down the machine or in the event of an electrical fault — the valve closes automatically, stopping fuel flow. The integrated filter catches debris in the propane supply line that could clog the valve seat or downstream components. A worn or failed valve can result in fuel starvation on LPG, fuel leaks, or an engine that will not shut off cleanly, making timely replacement essential for safe and reliable dual-fuel operation.
