Motor mount HICs Application notes CROSS-PORT RELIEF VALVES (continued) 16.14 Cartridge Valves Technical Information Motor mount HICs Application notes BLN-10201 • 520L0588 • Rev. CA • Nov 2007 Introduction Quick reference Index Motor with dual cross-port relief, and shuttle operating a brake and unloading valve Adding a load sense, or brake shuttle valve allows further functionality. In this circuit, an integral brake and an unloading valve (logic element), are added. The shuttle valve senses the higher pressure work port and provides pressure to release the brake when the system pressure exceeds the minimum brake release pressure. When the directional control valve shifts in either direction, pressure builds in the circuit to release the brake and allows the motor to rotate. As shown in the diagram, an orifice provides a slight delay in timing the brake release. When the directional control valve is centered, the brake re-engages. Additionally, the LS pressure signal pilots an unloading valve. When the directional control valve is centered, pressure builds at the outlet of the gear pump and opens the unloading valve, allowing the pump flow to bypass the circuit and exhaust into the reservoir. When the directional control valve shifts in either direction, the unloading valve is piloted to stay in the closed position, thus allowing pump flow to enter the working circuit. Similarly, this LS pressure could communicate flow demand to a load sensing open circuit piston pump. Dual cross-port relief with shuttle MA A S MB B P104 782 Motor with integral brake, system includes pump unloading valve.
BYPASS SOLENOID VALVES Cartridge Valves Technical Information Motor mount HICs Application notes The bypass solenoid allows an electric signal to enable/disable motor rotation independent of system hydraulics. The normally closed solenoid valve bypasses flow from B to A when energized. This function is unidirectional. Contact your Sauer-Danfoss representative if you require reverse logic. Bypass solenoid valve with robust coil BLN-10201 • 520L0588 • Rev. CA • Nov 2007 Introduction Quick reference Index Bypass solenoid MA 1 2 A D The manifold includes a drain port connected to port A to simplify circuit plumbing. Depending on motor drain pressure capabilities, you may connect the motor drain directly to port D on the HIC instead of routing it back to the reservoir. Typical uses for this valve include applications requiring individual motors on the same circuit to be turned off independently, disabling motor during system start-up to limit pressure losses, and on/off fan drive applications.
