Safety Wheels provide a secondary attachment to reduce the potential hazard of a falling valve hand wheel. Safety wheels use stainless steel wire to attach to a nearby pipe or other secure object to provide additional protection.
Available in the following materials:
- Cast Iron is our most economical material. It is recommended in mildly corrosive environments.
- Ductile Iron is more shock resistant than cast iron and is required for conversions to a hammer-blow style wheel.
- Corrosion Resistant is recommended when the chainwheel will be exposed to a corrosive environment. Available coatings for the chainwheel and all components are epoxy and galvanized. Both options come with stainless steel attachment sets.
Standard Components
- Chainwheel
- Guide arm and safety cap
- Zinc plated carbon steel attachment set for clamping to the valve hand wheel
- 5 feet of 7x19 stainless steel wire with 4 stainless steel clamps
- Attachment instructions for installing the chainwheel to the hand wheel of the valve

- Stainless steel attachment sets are the same dimensions as the zinc plated carbon steel attachment sets but are constructed out of 304 stainless. They are recommended for areas where the chainwheel or components will be exposed to corrosive environments. To add stainless steel attachment sets to your order, use the part numbers below and add “SS” to the end of the part number (e.g., CIRGSW-2.5SS).
- Chain is required for chainwheel operation but is not included in the price due to varying length requirements. For more information on chain, visit our chain section.
