6.2 Inf
l
ate / Def
l
ate valve
CAUTION:
ENSURE WHEN CONDUCTING THE REPAIR TO THE
SLIT, NO MEK COMES IN CONTACT WITH THE VALVE.
THE VALVE IS TO BE FITTED WITH THE SEALING PLUG
ATTACHED. NO OTHER CAP OR PLUG IS TO BE USED.
PLEASE REMOVE CAP AT THE END OF THE PROCESS.
Disassembly of the valve is not permitted. The Inf
l
ate/ Def
l
ate valve has no
serviceable components — a faulty valve must be replaced with a new unit.
Replace the complete assembly:
6.2.1 Removal method
(a) A slit of approximately 150 mm (6”), must be made in the
buoyancy tube in the vicinity of the affected valve to enable
access to the inside of the buoyancy tube. The slit should be
made along the length of the buoyancy. The end of the slit
should be no closer than 100 mm (4”) to the edge of the PRV
doubler.
(b) The slit should be made as small as possible and repaired
subsequently by patching according to standard practice.
(c) Loosen both parts of the valve using the appropriate tools.
(d) Remove the valve.
(e) Discard all parts of the faulty valve. Do not reuse any of them.
6.2.2 Fitting a new valve
WARNING:
UNDER NO CIRCUMSTANCES SHOULD OLD COMPONENTS
BE MIXED WITH NEW COMPONENTS. REPLACE THE ENTIRE
VALVE ASSEMBLY. DO NOT RE-USE ANY OLD COMPONENTS.
NOTE:
Ensure all surfaces are clean and dry before f
i
tting the
new Inf
l
ate/ Def
l
ate valve.
(a) Push the valve body into the slit, from which the faulty one was
removed.
(b) Assemble the valve body as shown in (FIGURE 605).
NOTE:
The ridged face of the clamp washer should be
positioned towards the buoyancy tube.
(c) Holding the valve body in place, through the buoyancy fabric,
hand-tighten the components of the valve using the nut.
