The Multiquip 14721ZH7810 Exhaust Valve Stellite is a genuine OEM component designed for QP2H, QP-204H, CA-4-4H, CA4HC, CA4HM, and CA4.4HM series equipment. As a direct Multiquip OEM part, the part is manufactured to the same specification as the original, ensuring a correct installation with no adaptation required. Confirm your model code against the fitment list before ordering to ensure compatibility with your specific unit.
Key Features
- Stellite-Faced Durability — Hard-faced Stellite alloy construction resists the extreme heat and corrosive combustion gases that cause standard exhaust valves to pit and burn prematurely.
- Genuine OEM Specification — Sourced directly from Multiquip, this valve is built to the same material grade, stem diameter, and head geometry as the original, so it seats and seals correctly the first time.
- Broad Model Coverage — Fits QP2H, QP-204H, CA-4-4H, CA4HC, CA4HM, and CA4.4HM series centrifugal pumps and walk-behind power trowels sharing the same engine platform.
- Combustion Efficiency Restored — A correctly sealing exhaust valve maintains proper cylinder compression, restoring full engine power output and fuel efficiency lost to a worn or burned valve.
- Fuel System Safety Compliance — A failed exhaust valve can allow unburned fuel and combustion gases to bypass the cylinder, creating heat buildup and combustion risk; replacing with an OEM-rated part keeps the engine operating within safe design parameters.
The exhaust valve controls the release of burned combustion gases from the engine cylinder at the end of each power stroke. It must open and close thousands of times per minute while exposed to extreme heat and pressure, making it one of the highest-stress components in the engine. When an exhaust valve burns, pits, or fails to seat properly, cylinder compression drops, power output falls, and the engine may run rough or fail to start. The Stellite facing on this valve provides a hardened seating surface that extends service life well beyond that of a standard steel valve in high-temperature exhaust conditions.
