 Variable Oil By-pass™ stroke adjustment allows
better valve performance than variable linkage designs. The valve checks have extra time to seat even in heavy liquids since they are idle during the by-pass portion of the suction and
discharge strokes.
EZE-CLEAN™ Valves–Cartridges can be removed for cleaning without disturbing the piping to the pump.
