Helical valve rotators operate by means of the increase in valve spring loads from valve closed to valve open. Our rotators can be manufactured in sizes ranging from 25mm to 150mm diameter. Each one is tailor-made for a specific engine application. We have the design expertise and flexibility to complete the development cycle rapidly from design to prototype stage, and then to on-time delivery of serial production.
All our valve rotators are tested to meet customers requirements. We have test rigs for engines up to 460mm cylinder diameter. Our rotators must have a long life span, extending to tens of thousands of hours. The quality and design of our rotators allow us to meet the demands of the toughest applications.
