Fixing Valve Leaks

Postby Stafford » Wed May 13, 2009 4:46 am

This is great info from Joe Swan:

hey man, i know i have shared some of this valve info before but i want to reiterate it AND give you or the installer some VERY helpful hints for installing the option valves - it comes from installing about a hundred of these suckers myself

ALL OLD VALVES
Do not pull off old valves, heat up water to a boil, let simmer a minute and then stick valve and bladder into water for 2 seconds, old valve peels right off, KEEP BLADDER MATERIAL AWAY FROM HOT POT

FILL/INFLATE VALVE
UNLESS your kite has plastic deflate sticks (like NORTH kites) sewn to the valve cover you must decide BEFORE installing a fill valve on struts or LE (leading edge) if you want a one way valve or a two way valve. If you look at the bottom of the Airtime fill valve you will see it is capped off except that a small slit has been made. FOR STRUTS - you can either cut this slit all the way thru (cut off the end) and it will be a two way valve that you will have to pinch off after filling the kite OR you can make the slit a little bigger and keep it as a one way valve BUT you will need to pinch the valve OR use a small dull stick in it to deflate the strut when finished kiting. ON LEADING EDGE IT IS STRONGLY RECOMMENDED THAT YOU CUT THE SLIT/CAP OFF SO THAT YOU HAVE A TWO WAY VALVE OTHERWISE, UNLESS YOU HAVE A NORTH STICK, DEFLATING YOUR LE WILL BE A PAIN IN THE ASS.

BEFORE installing the new Airtime valve you need to draw an arrow on the bladder so you know which way the valve and it's cap are oriented (the cap MUST match up with the cover sewn onto your kite strut or LE). Also follow directions using the alcohol wipe. MAKE SURE THE ALCOHOL HAS COMPLETELY EVAPORATED BEFORE INSTALLING THE AIRTIME VALVE.

Have another person assist you when installing a valve, they can stretch the badder material and keep it perfectly flat while you install the Airtime valve. TRY TO GET PERFECT ADHESION WITHOUT LITTLE VEINS BETWEEN THE BLADDER MATERIAL AND THE NEW VALVE - TAKE YOUR TIME STICKING THE VALVE ON. If you are alone use packing/Scotch tape to hold down the bladder material flat while you install. Some bladder manufacturers use a new process (a retarded process) that wrinkles the area directly under the old valve. If this happened on your kite it is VERY IMPORTANT TO HAVE AN ASSISTANT FLATTEN THE BLADDER MATERIAL AS MUCH AS POSSIBLE WHILE YOU TAKE YOUR TIME AND STICK ON THE AIRTIME VALVE - START RUBBING/PUSHING THE VALVE ON AT THE CENTER AND WORK OUTWARDS - IT IS IMPORTANT NOT TO GET ANY VEINS ON A WRINKLY VALVE - IT WILL BE A PAIN - JUST TAKE YOUR TIME.

DUMP/DEFLATE VALVE
Follow the same directions as above especially with orientation of valve cap. You do not need to worry about one way or two way as dump valves are only tow way (no slit/cap)

OPTION VALVE

I personally would recommend installing the plastic post and zip tie AFTER you have installed the valve because the plastic tube is longer than the valve body and so it sticks thru the end. This makes it VERY DIFFICULT to get the valve perfectly flat on the bladder material as the tube keeps the Airtime valve OFF the surface of the bladder.

There is slight assembly required. ONE - you need to install the plastic tube (smallest diameter goes in the Airtime valve all the way up to the little o-ring). It is BEST if you coat the insertion end with dish soap or it will be AS HARD AS HELL to insert. TWO - you need to install the ZIP-TIE on the base of the valve, just under the thick plastic, oval lip.

Follow the same instructions as described in the fill valve paragraph (no slit/cap to worry about) however you do need to mark the bladder (both LE or strut) as to the orientation of the oval valve lip - this is only important if you have a Cabrinha kite that utilizes the black base connectors - you want the oval to fit properly in the black base connectors so note that on the bladder with a felt tip marker.

IMPORTANT - after you have installed the Airtime option valve you are ready to install the plastic post - BE SURE TO HOLD THE VALVE IN YOUR HAND AND INSERT CAREFULLY SO THAT THE HARD END OF THE PLASTIC POST DOES NOT HURT/PENETRATE/STRETCH THE BLADDER MATERIAL INSIDE THE KITE - NEVER LAY THE BLADDER ON A HARD SURFACE AND PUSH THE POST IN - YOU WILL CUT A CIRCULAR HOLE IN YOUR BLADDER
