The valves are in a constant dance with the pistons, kept in sync via the timing belt or chain. If the timing belt snaps or jumps, then the powerful piston may touch the valve and this will cause a bent valve. An engine where the piston and valve can overlap is known as an interference design - most modern engines are of an interference design.

Engine Valve Manufacturing. The remanufacturing process begins with valve core that is usually provided by our customers. As you disassemble the engine heads, simply drop the worn engine valves into shipping crates rather than into a scrap bin. There's no need for you to do any cleaning, inspecting, or sorting of the valves.

Valve lapping is a process that ensures a perfect fit for the intake and exhaust valves in the engine cylinders on their seats. Usually lapping is performed after performing an engine overhaul, or when the old valves are replaced with new ones . Lapped valves provide maximum tightness in the combustion chamber, ensuring engine

2019-3-12 An automotive engine uses valves for it’s ‘breathing’ (inhale/exhale) process. The engine's camshaft opens and closes the valves at a specific interval. The timing of the opening closing of valves is specified in degrees corresponding to the position of engine's pistons. Engine valve timing is the most critical process
