Abstract
A system includes a valve, handle, guide, arm, channel, and projection. The handle is proximate the valve and is configured to open and close the valve. The handle is in a first position when the valve is open and in a second position when the valve is closed. The guide is connected to the handle. The arm is connected to the guide. The channel is located on one of the guide or the arm, the channel having opposed first and second ends. The projection is located on the other of the guide or the arm, the projection configured to be received in the channel. Moving the projection past a location of the first end of the channel pulls the guide and the handle, thereby moving the handle from the first position to the second position. The projection can be moved toward the second end while the handle remains in the second position.
