Repairing a valve
 |
Mark the side of the valve, here I have used 'Tipp-Ex' to ensure that the cap goes on the right way round when you reassemble it. |
 |
Loosen the two screws that hold the base on. |
 |
Remove the base, being careful not to lose or damage the 'O' rings. |
 |
In this model there are two, one large and one small. Check to make sure they are okay, and slide the end cap to one side. |
 |
Carefully remove the spool, they are easily damaged. Use something inserted into one of the ports to lever it out. Do not use excessive force. |
 |
Once the spool is out. clean it, and make sure that the 'O' rings are in good order. Apply a small amount of light lubricant and reinsert into the body. Reassemble the valve, making sure that the dots in figure 1 are aligned once again. |
Now you have your valve back together, you can refit it to the manifold. Test it thoroughly, to make sure it is 'switching' correctly.
