If you have a ball valve that is either stiff to turn or has a slight leak, or needs to be stripped down for general maintenance, follow these simple steps :
1a. Unscrew the union from the main body of the ball valve. 1b. This will reveal the recesses that the key is going to turn.
The top surface of the handle has 2 protrusions that act as the 'key.'
3a. Pull the blue handle away from the valve to detach it completely. 3b. You will use the keys on the top part of the handle to turn the valve.
Turn the handle over then insert the handle into the recesses.
If you have a slight leak you should turn the handle clockwise to tighten the central fitting.
If the ball valve is sticking or is too tight you should turn the ball valve anti-clockwise to loosen the central fitting.
If your initial problem has been resolved, you should re-attach the handle (5a) and screw the union back on (5b). This will return the ball valve back to its original state.
If you need to carry out further cleaning or maintenance, or you need to strip the ball valve down completely, please proceed to step 6.
Step 6You can remove the whole fitting to access and remove/replace the white e.p.d.m. seal and even the ball. It is the e.p.d.m. seal and its contact with the ball that determines the handle torque.
If a small leak develops, stop it instantly by tightening the central fitting clockwise. This will also increase the pressure needed to turn the handle. When reducing the pressure due to stiffness, make sure that you don't loosen too much and create a leak
