|
Increasing valve life by rotation
 Where are Rotators used?
 Garter Spring Design
- Low cost, high volume applications
- High speed, low valve spring load applications
 Ball and Spring Designs
-
Higher valve spring loads
-
Larger engines 75mm to 640mm Bores
-
For higher contact stress applications
In these applications the rotators must have a long life span, extending to tens of thousands of hours. The quality and design of Helical rotators allow us to meet the demands of the toughest applications.

These are used on large diesel and gas engines. Each time a valve closes, the valve rotator turns the valve slightly, and allows the inlet and exhaust valves to be heated and cooled symmetrically. It also prevents valves sticking due to uneven carbon build-up, or wear on the valve seat.
