Normal Valve Operation

It is very important for the operators to learn how to close and open ordinary valves properly.

To close a valve do not use excessive force. Handwheels are designed to create enough leverage to allow good closure of a valve.

To close a valve, turn the handwheel to let the valve reach its full close position. Using your hands, tug on the handwheel to ensure it cannot move any further. Now, back off the handwheel a quarter or a turn or so. This will ensure the plug is fully closed, but not jammed against the valve seat.
