use the optional set screw to make sure that the external cap cannot be removed
from the valve, gently tighten the set screw with an Allen wrench until the head
almost touches the cap body. Test to ensure that the external cap is able to be
loosened approximately two full turns and then stops. If the cap seems to bind,
back the set screw out slightly until the movement is unimpeded. Use of the set
screw is optional– however it can prevent accidental loss of the cap.
Valve Operation
When the cap is turned clockwise and snug against the suit shoulder, the valve is
completely closed and inoperable. No fl uids can be discharged or enter the suit.
When the cap is turned counterclockwise approximately two turns, the valve is
operational and fully automatic. Fluids can be discharged at will, but water can-
not re-enter the valve due to the one-way check valve.
The valve is designed to be used with the cap in the open position during diving,
and really need only be closed in the event of failure. Normal valve travel is ap-
proximately two turns from the closed to fully open position.
Failure Modes
Kinked Hose
The use of the norprene tubing has drastically reduced the likelihood of a kinked
hose. The valve is best positioned to avoid sharp bends in the hose routing to
further reduce the risk of kinking. Use only Halcyon P-Valve hose for any replace-
ments.
Kinked/blocked Condom Catheter
This may occur in the event that the catheter was not properly/completely in-
stalled. Blockages in fl ow may be due to a sharp bend at the end of the catheter,
or a restriction created by the adhesive within the catheter. Be sure to follow the
catheter instructions carefully.
Check Valve Failure
Debris or deposits can build up on the check valves over time and interfere with
their function. Follow a periodic maintenance and cleaning schedule as recom-
mended in this manual. Replace any worn or damaged check valves.
Maintenance and Cleaning
The Halcyon Streamline P-Valve, like all valves used in scuba diving, should have
a basic maintenance check on regular intervals. If not cleaned properly, organic
and inorganic deposits will, over time, reduce the valve’s ability to function
properly. Additionally, regular cleaning of the Streamline P-Valve is essential in
preventing bacterial growth that could contribute to a urinary tract infection.
