Regardless of the distance between points, elevations, directional flows and space constraints, we can engineer a Roto Hammer® valve operation system that will work for you. No company can afford downtime, and with our Custom Solutions for valves, you’ll be back up and running sooner. Turnaround for most applications averages less than one week. And when you call us, you’ll speak directly with Roto Hammer’s management team, experts in the field.

When ordering, the following information
is required:

1. Valve size and type
2. Diameter of existing hand wheel
3. Length of extension required
4. Fill out Hand Wheel Replacement Data Sheet

If extension will be in horizontal position and longer than 3’, we recommend the purchase of an Extension Rod Support Bearing for additional support.


Provisions must be made to prevent the HANDWHEEL RETAINING NUT FROM BACKING OFF whenever a chain wheel is installed. To insure safe operations, Roto Hammer recommends that thorough inspection of all chain operated valves be performed as a routine part of the user’s Safety/Maintenance Schedule. Set screws and other threaded fasteners MUST be secure and tight.

In addition, it is strongly recommended that an appropriately sized Roto Hammer RCK Safety Cable Kit (optional) be installed on every overhead chain wheel operated valve.
