  • Chain Wheels

  • Chain wheels make it easy to operate overhead valves safely from the floor. These products have been keeping workers around the world safe for over half a century. The chain wheels fit all standard valve sizes and can be operated by simply pulling on the sprocket chain. Even high-pressure valves can be made easy to operate with Hamer-Blow units, which fit all handwheel sizes from 6" to 36".

    The Hammer-Blow includes the sprocket rim, chain guide and hammer-blow mechanisms. They are built from corrosion-resistant stainless-steel 

    Dimensions: When placing an order please give the diameter of the valve wheel to be fitted, as well as the number of feet of chain required.

  • *#2 is available with a special attachment plate to accommodate 6" - 71/2" handwheel diameters.

  • Solid Hubs

  • Solid Hubs mount directly to the valve or geared operator stem, therefore eliminating the need for handwheels. The solid hub controls the overhead valves and allows direct-to-shaft operation, making way for safety and efficiency. The solid hub is custom designed for all wheel sizes. It is available in cast or ductile iron, and also aluminum for corrosive applications.

    Solid hub sprockets with chain guides do not come shipped with mounting hardware.
