AD Piston Ring manufactures valve rings for steam cylinders.
A valve ring is the valve in the steam cylinder. The valve ring incorporates a pin so that depending on how it sits in the cylinder, it acts as a swing to keep the valve in place.
Valve rings can be made of cast iron and bronze aluminum materials.
