Design Philosophy
Precision-engineered exhaust valve made from chrome-steel with a heat-treated head and black coating. Designed to withstand extreme exhaust temperatures and repeated impact loads, ensuring reliable sealing and efficient exhaust flow in Isuzu commercial diesel engines.
How It Works
Installed in the cylinder head, the exhaust valve opens to allow burnt gases to exit during the exhaust stroke and closes to seal the combustion chamber during compression and combustion. The 45° seat angle ensures precise sealing against the valve seat.
Problems It Solves
Fixes compression loss, power drop, exhaust smoke, and engine misfire caused by burnt, bent, or worn exhaust valves. Restores proper cylinder sealing and exhaust efficiency in NPR75 / NQR71 / NQR75 / 700P trucks.
