Inverted Plug style valves have the large diameter of the plug at the bottom of the valve. The plug is held in position by the bottom cap which also contains a treated leather gasket. A channel is cast into the Inlet side of the valve body to allow water at the main pressure to go under the plug, exerting an upward pressure on the plug which reseats it after cycling. To cycle the valve, hit down on the top of the plug or rod. This forces the plug down slightly, breaking the plug away from the body taper, thus lowering the turning torque momentarily (the leather gasket in the bottom cap absorbs the blow). Water pressure from the main then reseats the plug. The valve must be placed on a brick or other solid foundation to properly support the valve when it is hit to lower turning torque. Most styles of end connections are available as well as Minneapolis Pattern Curb Box Threads.
