    Why become a Subscribing Member?

    • In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.
    • We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction).
    • Annual membership also comes with two BiplaneForum.com decals.

Anyone seen this magnetic shut off valve? Magnetism opens a valve, a tension spring close it when power off. My spring is ruined, need a new valve like this or what kind of valve do you guys use today?
