VALVE INSTALLATION

Directly to the socket.
1. Fabricate the socket as usual.
2. Mark the position of the valve onto the socket.
3. Using an 8.5mm (5/16") drill bit, make a hole perpendicular to the
socket wall.
4. Tap the hole using M10x1.5 tap.
5. Prior to shortening the threads, make sure that the inner housing has
been separated from the outer housing.
6. Ensure the cap and rubber membrane and air filter have been removed
prior to shortening the threads to prevent debris lodging in the airways.
7. Measure socket wall thickness at insertion point with a caliper, and
shorten the threads accordingly using a hacksaw and smooth edges.
important: Do not shorten the threads beyond 4 mm (3/16") as it may
affect the seal and increase the risk of the valve breaking off. It is
recommended that the socket wall thickness at valve insertion point is to
be equal or more than 4mm (3/16") in thickness (Figure 3).
Using the socket insert (Figure 2).
1. The socket insert is used as a fixation device for the valve, and should
always be used when fabricating a flexible inner socket.
2. Prepare the plaster cast as usual.
3. Fix the socket insert to the cast using the set screw. Ensure it sits
flush to the cast.
