New Order for Needle Valve Locking Device

Our innovative locking device for needle valves has been selected by Wm. Coulthard & Co. Ltd in a batch of 20 pieces. This novel design can be adapted to suit any size of needle or other instrumentation valve with a rotating handle/lever.

The locking device incorporates a key mechanism which can be released in any position. Once the key is removed the drive mechanism disengages and the locking handle free-wheels preventing further operation.
