Valves Add Flexibility to Existing Hydraulic Systems


Heavy-duty priority flow control valves from Bosch Rexroth provide a simple and efficient way to supply auxiliary hydraulic power to mobile work tools. The valves can be added to any existing hydraulic system to maximize machine utility without the need to modify a machine’s directional control valve. The valves feature zinc-plated steel bodies and IP69-rated coils that can perform in the most severe operating conditions of mining and heavy industry and are ideal for applications such as earthmoving machines, loaders and excavators. The priority flow control valves, also called hammer valves, are now available for single pump, double pump or load sensing, and can be used with any attachment or application where precision flow meets severe service or high vibration. Hammer valves feature three-way configuration: one pump inlet port and two outlet ports for priority and by-pass flow, allowing for simultaneous operation, independent of working pressures, of both the hydraulic actuator and the normal functions of the machine. The valves’ unique mounting hole arrangement reduces stress on moving parts from possible misalignment and minimizes the risk of malfunction.
