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. Ensure the cap and rubber membrane have been removed prior to shortening the
nozzle to prevent debris lodging in the airways.
6. Measure socket wall thickness at insertion point with a caliper, and shorten the
nozzle accordingly using a hacksaw and smooth edges.
IMPORTANT: Do not shorten the nozzle 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 C)
Using the socket insert. (Figure B)
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.
4. Plaster may have to be removed or added.
5. Apply the foam cap to the set screw.
6. Fabricate the socket as usual.
7. Grind material away over the socket insert until foam cap is fully exposed.
8. Unscrew the set screw to remove socket from cast.
9. Ensure the cap and rubber membrane have been removed prior to shortening the
nozzle to prevent debris lodging in the airways.
10. Measure socket wall and socket insert thickness at insertion point with a caliper, and
shorten the nozzle accordingly using a hacksaw and smooth edges.
IMPORTANT: Do not shorten the nozzle beyond 4 mm (3/16") as it may affect the
seal and increase the risk of the valve breaking off. (Figure C)
ASSEMBLY.
1. Apply silicone adhesive to the threads and housing, where it comes in contact with
the socket.
NOTE: It is not recommended to use epoxy or similar as it can compromise the seal.
2. Install valve and hand tighten with a 5mm hex key.
NOTE: Be careful not to over-tighten as it may damage the threads.
