If you have a Valco W Type valve with no hardware and want a knob on it, or if you are converting an air or electrically actuated two position valve to manual use, this is what you need.
There are two versions: one for valves with threaded mounting holes and one for valves with unthreaded mounting holes. (If your valve has no mounting holes, you will have to use it with a standoff.)
|For valves with:||Product No.|
|Threaded mounting holes||WMMA|
|Unthreaded mounting holes||WMMA10|
