The E Series Direct-Mount Chain Wheel is designed to provide a truly custom fit. Instead of clamping on to the existing hand wheel, the E Series mounts directly to the valve stem and replaces the hand wheel. This eliminates the need for multiple clamps and hardware sets and provides a more streamlined, secure fitting of the chain wheel to the valve. The E Series can be bored to customer specifications or shipped solid for machining by the customer.
- Aluminum E Series replaces hand wheel sizes from 4 to 30-1/4 inches
- Ductile iron E Series replaces hand wheel sizes from 8-9/16 to 30-1/4 inches
- All units come complete with sprocket wheel, chain guide, set collar and installation instructions
- Available in ductile iron or light-weight aluminum
- Mounts directly to the valve stem and replaces the existing hand wheel
- Center hub is available blank or machined to fit customer requirements
When ordering, provide diameter of existing hand wheel, length of chain required and centre bore dimensions.

CAUTION:
- Whenever a chain wheel is installed, provision must be made to KEEP THE VALVE HANDWHEEL RETAINING NUT FROM BACKING OFF THE STEM. This best done by installing a SET SCREW that secures the nut to the stem.
- 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.
- As an additional safeguard, Roto Hammer strongly recommends that ALL chain wheels be fitted with an appropriately sized Roto Hammer RCK Safety Cable Kit available from H & N Supplies.
- 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.
