Each time a valve opens, the valve rotator turns the valve slightly. This prevents the valves sticking due to carbon build up. Additionally, it allows the inlet and exhaust valves to be heated and cooled symmetrically.
Fitted to the top or bottom of the valve spring, the valve rotator helps to keep valves cleaner, reducing carbon build-up and so lowering engine emissions – as well as extending the life of key engine and valve gear components.
Valve rotators help to reduce the amount of carbon deposits on the valve and prevent carbon build-up on the valve seat. Cleaner valves reduce engine emissions and prevent burning and guttering of the valve face and seat. Valve rotators reduce thermal gradient and stress, reducing the need for high-cost nimonic steel valves.
Our rotators are easy to replace during engine service and allow longer engine service interval, extending the life of key engine and valve gear components.
