Can the valve stem be lengthened?
Valve can be extended, such as the valve position is far from the operating position, you can process the connecting rod, equivalent to the role of stem.If you want to improve the original valve parts (valve stem), you must know the valve condition to lengthen. The extended stem must be bent.
Make a longer valve wrench, so it is much easier to switch the valve.
The extended stem also takes into account the torque and the medium of the valve. Not all valves need to be extended. Generally in the buried ball valve and cryogenic valve needs longer stem.
