Motor Mount HICs Catalog Application Notes This family of motor mount HICs (Hydraulic Integrated Circuits) complements Danfoss Power Solutions orbital motors—also know as Low Speed, High Torque (LSHT) motors. These HICs perform several complementary functions common in LSHT motor applications. Motor mount HIC family MM - Motor Mount HICs Catalog Application Notes There are four basic types of HIC functions, or schemes, with additional functions available: · Counterbalance (or overcenter) - Dual or single valve on A or B port - With or without brake shuttle · Cross-port relief - Dual or...

Motor Mount HICs Catalog Application Notes ORBITAL MOTORS · Off-the-shelf solution of common valve functions applied with orbital motors There are seven specific Danfoss Power Solutions orbital motor types in this program. The table below highlights the motors and their basic technical information. For more information refer to the technical information manual number in the table. HICs fit only the porting configuration shown. Danfoss Power Solutions orbital motors compatible with HICs Motor type Displacement range Max pressure drop* [intermittent] 2400 psi 166 bar 2500 psi 172 bar 2540 175...

Motor Mount HICs Catalog Application Notes ORBITAL MOTORS (continued) Important notes · Motors are sold separately from HICs. - Contact your Danfoss Power Solutions representative to order motors. - Refer to the motor technical information manual for detailed motor information. · Mounting bolts and O-rings are included with the purchase of the HIC. - The service mount kit allows ordering of just bolts and O-rings. - All O-rings are viton. · All HICs in this program are aluminum, except the dual shock valve HIC. - Dual shock valve housing is ductile iron. - For ductile iron on any other HIC,...

Motor Mount HICs Catalog Application Notes Counterbalance valves prevent motors from drifting excessively due to control valve leakage. They can hold the load in the event of hose/tube failure, or limit overrun when a load is in a lowering or runaway mode (vehicle going downhill). They provide a smooth, cushioned stop when the control valve is suddenly closed. Dual counterbalance valve MA COUNTERBALANCE VALVES With Shuttle Without Shuttle Counterbalance valves have a pilot ratio of 3.0:1, 4.5:1, or 10.0:1. Typical pilot ratio for motor applications is 10.0:1 An optional shuttle valve is...

Motor Mount HICs Catalog Application Notes COUNTERBALANCE VALVES (continued) Sample system circuits Motor with dual counterbalance valve A typical rotary circuit application for a counterbalance valve contains a pump, directional control valve, system relief valve, and motor. Without a counterbalance valve there is no back pressure to hold the load on the motor, or to prevent free rotation when the control valve shifts to the neutral position. Additionally nothing prevents motor rotation in the event of hydraulic line failure. A counterbalance valve controls motion. It also provides...

Motor Mount HICs Catalog Application Notes COUNTERBALANCE VALVES (continued) Motor with dual counterbalance valve 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...

Motor Mount HICs Catalog Application Notes CROSS-PORT RELIEF VALVES The cross-port relief valve controls maximum torque of the motor. It provides overpressure protection for the work ports. The cross port relief valve is a full-flow relief. It can bypass all motor flow when pressure reaches the relief setting. Dual cross-port relief with shuttle MB With Shuttle Without Shuttle Typical applications for cross-port relief valves include vehicle propulsion, auger drives, conveyer drives, and slew drive. Any rotary application requiring pressure limiting can benefit from a motor-mounted...

Motor Mount HICs Catalog Application Notes CROSS-PORT RELIEF VALVES (continued) Motor with dual cross-port relief A typical rotary circuit application for a cross-port relief valve contains a pump, directional control valve, system relief valve, and motor. Without a cross-port relief valve there is no overpressure protection at motor work ports. A cross-port relief valve controls motor torque while reducing system component fatigue. In this circuit, a dual cross-port relief HIC is mounted to a standard motor, providing Dual cross-port relief functionality in both directions. Moving the...
