The Honda 14721-Z4V-910 Exhaust Valve (Stellite) is a genuine OEM component designed for the GX200 horizontal shaft engine. As a direct Honda OEM part, it is manufactured to the exact specifications of the original valve it replaces, ensuring a correct seat contact, proper stem diameter, and full compatibility with the GX200 valvetrain. This exhaust valve carries the Stellite designation, identifying it as the hardened-face variant — confirm your engine's original specification before ordering to ensure this is the correct valve for your unit.
Key Features
- Hardened Exhaust Face — the Stellite designation identifies this as the hard-faced valve variant, engineered to handle the elevated temperatures and impact loads of the exhaust seat on the GX200
- Genuine Honda OEM Part — sourced directly from Honda, this valve meets the exact dimensional and metallurgical standards of the original, including stem diameter, head geometry, and seat angle
- Built for the GX200 Horizontal Shaft Engine — designed specifically for GX200 engines; verify your engine's serial number against the fitment table to confirm this is the correct valve variant for your unit
- Restored Compression and Combustion Sealing — a worn or burnt exhaust valve allows combustion gases to escape past the seat, causing hard starting, lost power, and excessive fuel consumption; replacing it restores proper cylinder sealing
The exhaust valve controls the release of spent combustion gases from the cylinder after each power stroke. It opens on the exhaust stroke to let gases escape, then closes and seats tightly against the cylinder head to maintain compression on the next cycle. Because it is exposed to extreme heat and the corrosive byproducts of combustion every time the engine fires, the exhaust valve is among the most thermally stressed components in the valvetrain. When the valve face or seat wears, burns, or develops a poor seal, compression drops, power output falls, and the engine becomes difficult to start. Replacing a failed exhaust valve with the correct genuine OEM part restores full cylinder sealing and returns the engine to its proper operating condition.
