|WS BFP Water Feed Valve|
|And the same but closer (restored)|
|The 'Plug' (Spindle)|
There is a slot around the top of the plug taper with a pair of holes diametrically opposite each other. So what are they for?
On the top of the spindle is also a hex headed screw. So what's that for?
|Hex head screw|
On removing the hex head screw, I could see another screw inside the spindle hole so I removed that too.
|Hex head and internal screws|
The internal screw is more subtle than I'd initially imagined.
With the screw in place at the bottom of the spindle hole, grease is loaded into the hole above (best done with a grease gun). The hex head screw is then screwed in to push the grease through the valve and out through the holes to the slot around the top of the plug.
The valve body design works with the plug to distribute grease to all the places it is needed.
|Inside the valve body|
|One of the four plug slots - Note the dark patches at each end of the slot|
which match the top and bottom body cut-outs
A few notes:
Grease can be forced in with the valve spindle in any position. The cut-outs will prevent grease ending up in the water space.
The valve is open when the top looks like this:
