Hand Wheel
I am looking for a solid hand wheel (no spokes) for a valve application. The challenge is that I need it to be 16" in dia.You will be adding a lot of extra weight to a valve. In carbon steel a 16" dick will weigh about 50 pounds. Depending on the type of valve and the orientation of the installation there could be added torque on the valve stem that would void the warranty. They are made, we had some Al hand/valve wheels about 24" in diameter for use on gear operated valves. The primary purpose was to prevent the use of a valve wrench. These wheels were cast aluminum with what could be called scalloped edges for gripping. I'll try tomorrow to see who made them. We also had some CI wheels that were solid except for about 4 lightening holes these also had scalloped edges. Again these were used to prevent using a valve wrench. You might look at a hammer valve wheel as a lot of them are solid. All you would have to do is remove the hammer.
