Question:

Valve handwheel can move, stem does not move what is the matter?

Valve handwheel can move, stem does not move what is the matter?

Answer:

Valve plate should be killed, the reason may be between the valve plate and valve casing into the foreign body, or a long time without rust dead.If the stem is a screw, you can use a long lever to turn the handwheel. Not really, you have to check out the valve.

See if the keyway between the stem and handwheel is broken.
