Manually Operated | 700 bar | 3/3-Way and 4/3-Way | Size 1 and Size 2
The Yale VHP and VHH range comprises manually-operated hydraulic directional valves rated for 700 bar maximum operating pressure. The valves control oil flow in combination with hydraulic power packs (the VHH-4/3 specifically with hand pumps). All valves have three lever positions: advance (left), neutral/pressureless circuit (middle), and retract (right).
Manual directional control for Yale 700 bar hydraulic systems
Yale documentation explains that in the middle position (hold), the piston of the cylinder stops and the oil flow is guided in a circuit back to the reservoir (P to T). Valves can be flanged directly onto power packs or remote-connected via hydraulic piping. All valves are equipped with a second pressure oil port P at the back of the valve base for connection of a pressure gauge and pressure relief valve (e.g. VPR-1). The oil port T should always be connected to the reservoir without any back pressure.
Per Yale: combination with hydraulic power packs and (for VHH-4/3) with hand pumps. The VHH-4/3 has a special small design for direct mounting to all HPS hand pumps using connecting set FY-703.
