Abstract
A manifold is part of the hydraulic system of a transport vehicle and controls both the product pump from the tank for unloading product and a hydraulically powered and controlled hose reel. The manifold includes a high pressure input port and a main return port tied into the hydraulic circuit on the vehicle, as well as two ports for the product pump and two ports for the hose reel. Control valves for both the product pump and the hose reel are mounted on and connected within the manifold block. The control valve for the hose reel preferably allows either forward (winding) or reverse (unwinding) of the hose reel under hydraulic power, as well as easy free spooling of the hose reel. A priority flow valve is also mounted on and connected within the manifold block, providing a higher flowrate to the product pump than to the hose reel motor.
