The Multiquip 6162131322 is a genuine OEM Seat Valve (Ex) SA6D170BE-1 designed for equipment powered by the Komatsu SA6D170BE-1 diesel engine. Sourced directly through Multiquip's OEM supply chain, this exhaust seat valve delivers the exact material hardness, dimensional tolerances, and sealing geometry specified for this engine family. Confirmed fitment for SA6D170BE-1 engine applications — verify your engine code before ordering to ensure a direct match.
Key Features
- OEM-Grade Valve Seat Material — Manufactured to the hardness and thermal resistance specifications required for the exhaust port environment of the SA6D170BE-1, where heat cycling and combustion pressure are most demanding.
- Direct Drop-In Installation — Engineered to the exact seat diameter and depth of the original, allowing installation without additional machining or fitting adjustments during a cylinder head rebuild.
- Confirmed SA6D170BE-1 Fitment — Designed specifically for the SA6D170BE-1 engine series; always cross-reference your engine model code to confirm compatibility before installation.
- Exhaust-Side Durability — Built to withstand the elevated temperatures and corrosive exhaust gases present on the exhaust valve side, helping the cylinder head maintain proper compression and combustion efficiency over extended service intervals.
- Combustion Seal Integrity — A correctly seated exhaust valve prevents compression loss and hot gas blow-by, both of which can lead to power loss, excessive heat buildup, and accelerated wear on surrounding head components.
The exhaust seat valve is a precision-machined insert pressed into the cylinder head that provides the hardened seating surface against which the exhaust valve closes during each combustion cycle. Because the exhaust side is exposed to the highest temperatures in the engine, the seat must resist wear, heat distortion, and chemical attack from combustion gases. When an exhaust seat valve wears, cracks, or loosens, the result is poor valve seating, compression loss, misfiring, and in severe cases, damage to the valve itself and the cylinder head. Replacing a worn seat valve with a correct OEM part restores the tight seal the engine needs to run at full power and efficiency.
