Hammerblow Handwheels

[Dooward]

I was wondering if someone could give me a good description on how a hammberblow hand wheel works. Apparently, they're standard for a 2" 1500 globe valve. Is this true? Thank you

Dooward,
maybe you'll find a little more information on the following web-page:

Hope this helps, 'NGL
