The lock valve is a ball-type valve that rotates
1/4 turn per command. The ball, placed in the
passageway (thru which gas fl ows), has a hole thru
it that enables the valve to open and close. When
the ball is positioned with its hole lined up with the
passageway, the gas fl ows thru the hole and the
valve is considered open. When the ball is positioned
so the hole is perpendicular to the passageway, the
gas cannot pass thru and the valve is considered
closed. The ball is controlled by the cam located
outside the valve.
