摘要： The valve operating apparatus cycles valves between open and closed positions. The valve operating apparatus includes a trailer for use in towing behind other vehicles, for instance, behind a pickup truck. The trailer includes an engine, pump, battery, reservoir and a bidirectionally oriented motor which is suspended from a telescoping extension bar. The operation of the valve operating apparatus is substantially balanced and requires very little effort by the operator to operate. Specifically, the operator does not have to push down or lift the apparatus as it is substantially balanced.
