The Multiquip 14721Z4M000 is a genuine OEM Exhaust Valve designed for a range of Multiquip gasoline-powered generators and plate compactors, including the GA2.5HR, GAC2.5HR, MVC88VTH, MVC88VTHW, MVH128GH, MVC82VH, and MVC82VHW. As a factory-authorized component, it meets the exact dimensional and metallurgical specifications required by the original equipment manufacturer. Sourcing a genuine OEM part means you are installing the same valve that came in the machine at the factory — no guesswork on compatibility. DHS Equipment stocks Multiquip OEM parts so you can get your equipment back in service quickly.
Key Features
- Genuine OEM Metallurgy — Manufactured to Multiquip's original heat-resistant alloy specification, ensuring the valve withstands the high-temperature combustion environment without premature wear or warping.
- Direct Drop-In Fitment — Machined to the exact stem diameter and head dimensions of the original, allowing the valve to seat correctly in the cylinder head without additional machining or shimming.
- Broad Model Coverage — Compatible with GA2.5HR, GAC2.5HR, MVC88VTH, MVC88VTHW, MVH128GH, MVC82VH, and MVC82VHW equipment, making it a versatile stock item for fleets running multiple Multiquip machines.
- Restored Engine Compression — A correctly seated exhaust valve maintains cylinder compression and efficient combustion; a worn or burnt valve causes rough running, loss of power, and hard starting across all compatible models.
- Critical Fuel System Safety — Proper exhaust valve sealing prevents combustion gases from escaping into the valve train area, protecting surrounding engine components and maintaining safe exhaust routing.
The exhaust valve controls the release of burned combustion gases from the engine cylinder at the end of each power stroke. It opens and closes thousands of times per minute under extreme heat and pressure, relying on a precise seat contact to seal the cylinder during compression and combustion. When an exhaust valve wears, burns, or loses its sealing contact — whether through normal service life or overheating — the engine suffers a drop in compression, leading to reduced power output, increased fuel consumption, and difficulty starting. Replacing a worn exhaust valve with the correct OEM part, such as the Multiquip 14721Z4M000, restores proper cylinder sealing and returns the engine to its designed operating condition.
