text: defining a valve element sealingly engageable with the adjacent valve seat, the length of said valve rod being substantially equal to the distance between said valve seats so that when one element sealingly engages its adjacent valve seat, the other valve element is spaced from its adjacent valve seat; said diaphragms having openings therethrough whereby fluid pressure within the respective chambers will act on both sides of the diaphragm therewithin; said housing having three ports extending therethrough, one of said ports communicating with said passageway and the other two ports communicating respectively with the respective chambers at a location therein close to the adjacent valve seat and between the diaphragm and the adjacent end of said passageway; and axially movable actuating means extending through the remote end of one of said chambers and continuously engaging at least one of said valve rod and the diaphragm therewithin for moving said valve rod axially and thereby flexing said diaphragms.
