Alternate Static Valves

Phil · #1 03-21-2010, 07:34 PM

I'm going to be installing an alternate static system into the airplane and I'm trying to find a source to acquire valves of various types.

Checking around Spruce, I can't seem to find anything there.

Anyone have a source that sells valves?

I bought an alternate static kit from SafeAir. I am not going to use it and will be selling it brand new in the original packaging. I forget what they sell it for. If you look and see that it would work for you send me a PM.

Thanks Tony. I think I've seen those. Aren't they the one that has the insert that you pull out of the fitting?

If so, I'm looking for one that's a little cleaner in the panel. I really like the Cessna type that you just pull out and the valve opens. But found a few references online for $350!!! Couldn't actually find any for purchase (didn't have the part numbers), but just saw an online discussion about them.

I used a pneumatic toggle switch... it was only ten or twelve bucks, if I recall correctly.

Here are a couple alternatives......

Then there is the Piper approach, which is basically just a schrader valve. I can remembered how upset I was when I purchased the official Piper part to put one in my Cherokee when I found out it was identifical the the fuel drain valves. Piper gave it a fancy important name, then marked it up 3,000%.

I will be going with one of the valves above and I like Matt's approach with a the safety cover.

Yes, the SafeAir alternate static is pretty basic. I think it around $25 so I guess I got what I paid for.

Thanks.

I ordered the TV-2SP from Clippard and also ordered an adapter from Avery that is:

1/8" NPT (Female) -> Quick Disconnect

This way I can make it a simple connection in the back of the panel.

Thanks,
Phil

I too like Matt's idea. Matt where and how will the static tubes plug into on the valve and what substance will hold them in place?

This is what I mentioned above:

This valve has an 1/8" NPT (male fitting).

I ordered this adapter from Avery. It's 1/8" NPT (female) to quick connect.

Simply shove the static line into the back of the quick connect. The static line will be seated and sealed by an O-ring and its got a retainer to keep the line from coming out. Pretty impressive stuff and insanely simple for the builder.

Just one connection is required - all you need is a NPT thread to quick-connect adapter, as mentioned by Phil above.

I goofed up and ordered a valve with male threads, so I will need to either find a female-NPT-to-tube adapter, or order a new valve with female threads as Phil did.
