Abstract
Two-way pressure relief valves featuring dual poppets and magnets that allow very rapid flow. Such flow is accomplished by a valve housing enclosing a hollow interior portion containing a stationary member including a magnet and a first pressure-movable poppet disposed in sealing arrangement with the housing and including a second magnet. To provide flow in the other direction, a second moveable poppet disposed coaxially and in sealing arrangement with the first poppet and is coupled to a spring that extends from a first end of the second poppet to a support structure coupled to the second magnet.
