Solenoid valve for creating a tail ballast dump system...Lak17a

[Sean Fidler]

I need advise or recommendations on what solenoid valve's (type, model) would work best for creating a tail ballast dump mechanism. My glider, unfortunately, did not come with a mechanical release. My glider is in the shop getting an evacuation vent and break away tail wheel so the time is right to do this. As part of the current project we are removing the tail battery and adding lead in the boom to reduce the chances of a tail break in a ground loop. We can also easily use the tail battery wiring to power the solenoid switch.

Anyone have any experience or info to help me? Thanks in advance. I need to buy a valve today or tomorrow so pace is key!

You may want to consider mechanical solution for valve. The bits used
by S-H would do nicely and it is a proven system.
Dead batteries lead to no dump.
When doing tail wheel, leave a way to inspect the bottom bulkhead area
of the tail tank. That is the first thing to get damaged in a ground
loop. It won't show from the outside, but the water leaking out will
make you want to inspect. You don't want to know how I know all this.
Take your time to do what you need long term.

If you have 12 or 24 volts available this SS and vitron solenoid valve
would work.

Keep in mind that especially for a tail water tank it might be crucial
that you get the valve opened, even with a dead battery.

My ASW 24 has electric valves for the wing tanks. They are made up of an
mechanical valve that is operated by a servo motor as it is used in R/C
model aircraft. This servo operates at 5V, so even with a dead battery
you should have enough voltage to operate the servo.
