The Roto Wheel combines two critical components for safe and dependable suspended valve operation: our Roto Hammer Chain Wheel complete with the addition of a fitted, factory installed retaining cable safety kit (RCK).

Simplify the ordering and installation process by purchasing a Roto Wheel (which combines our Chain Wheels with the popular RCK safety kits) or buy the Chain Wheel and RCK separately and install in the field.

The Roto Wheel is available in all Roto Hammer Chain Wheel Models (C, CL, E, and M Series).


  1. Whenever a chain wheel is installed, provision must be made to keep the VALVE HAND WHEEL RETAINING NUT FROM BACKING OFF THE STEM! This is best done by installing a SET SCREW that secures the nut to the stem.
  2. All chain wheel installations, regardless of age, must be regularly inspected as part of the user’s Safety/Maintenance procedures. Set screws and other threaded fasteners MUST be secure and tight.
  3. As an additional safeguard, Roto Hammer strongly recommends that ALL chain wheels be fitted with an appropriately sized ROTO HAMMER RETAINING CABLE SAFETY KIT available from your local distributor or Roto Hammer Industries.
  4. Maintain Handwheel and Operator – Retention of the chain wheel operator on valve stem is dependent on the handwheel remaining on the valve stem. The handwheel retaining nut MUST be secured with a set screw.
