The Multiquip 42200 is a genuine OEM LP Pressure Relief Valve designed for dual-fuel Multiquip ride-on screeds and power trowels, including the WRS5200, WRS5200DFPU, WRSPUDF, HTXG6DF, HHXDF4-DF5, STXDF, and PRX series. As a factory-original component, it meets the exact pressure tolerances required by the LP fuel system on these machines. DHS Equipment stocks this part to get your equipment back on the fuel system it was built for.
Key Features
- Exact LP System Pressure Rating — Manufactured to the original pressure relief specification for Multiquip dual-fuel systems, ensuring the LP circuit operates within the correct pressure range.
- Genuine OEM Component — Sourced directly from Multiquip, this valve carries the same part number and construction as what shipped with the machine originally.
- Broad Dual-Fuel Fitment — Compatible with WRS5200, WRS5200DFPU, WRSPUDF, HTXG6DF, HHXDF4-DF5, STXDF, and PRX series equipment — one part number spanning multiple dual-fuel platform models.
- Direct Drop-In Replacement — Designed to install in the existing LP fuel circuit without modification to fittings or mounting hardware.
- Fuel System Safety — A properly functioning pressure relief valve prevents LP overpressure conditions in the fuel circuit; a failed or out-of-spec valve can cause erratic engine behavior or unsafe fuel system pressure buildup.
The LP Pressure Relief Valve regulates propane fuel pressure within the dual-fuel system, acting as a safeguard that releases excess pressure if the LP circuit exceeds its designed operating threshold. This keeps the fuel delivery consistent and protects downstream components such as the regulator, carburetor, and fuel lines from pressure spikes. When this valve fails or sticks, the engine may run poorly on propane, surge, or fail to start on LP fuel altogether — making it a critical service item on any dual-fuel Multiquip machine.
