Technical Specifications 315-3394 - Exhaust Valve for CAT C4.4/C7.1 Engines

315‑3394 Exhaust Valve — High‑Temperature Alloy Steel Engine Exhaust Valve

The Cat® 315‑3394 Exhaust Valve is a precision‑machined valvetrain component for CAT C3.3, C4.4 and C7.1 diesel engines. Made of high‑temperature‑resistant alloy steel, it withstands long‑term thermal cycling and high‑pressure exhaust‑gas impact. It controls exhaust‑gas discharge timing and flow accurately, maintaining stable cylinder compression and ensuring reliable power output for construction machinery under variable heavy‑load conditions.
