Cartridge valves are compact and economical components that can be used for directional, pressure, or flow control in systems up to 400 l/min [100 US gal/min] and for pressures up to 350 bar [5,000 psi]. We offer over 450 cartridge valves in our portfolio -- from simple check valves to high-precision proportional valves. By combining standard cartridge valves in a hydraulic integrated circuit (HIC), you can create a custom manifold that provides hydraulic control.
Our mobile cartridge valves include:
- Check valves
- Shuttle valves
- Relief valves
- Pressure reducing valves
- Sequence and unloading valves
- Flow control valves
- Directional control
- Logic element valves
- Motion control valves
- Solenoid valves
- Proportional valves

We offer a broad portfolio of check valves, with flow ratings up to 310 l/min [82 US gal/min] and pressure ratings up to 350 bar [5,000 psi]. Integrated circuit solution (ICS) check valves include: standard, reverse flow, slip-in, and inline check valves. Screw-in cartridge valves may be either direct-operated or pilot-operated. Direct-operated check valves fit into industry standard cavities and may be supplied for installation in manifolds. Pilot-operated check valves are used for: a) Position load locking; b) As an alternative to counterbalance valves where neither the overrunning loads or release speed are factors in the application.
Danfoss offers two main types of shuttle valves – load and hot-oil shuttle valves. Load types may be configured in either a normal or in-line direction. With flow ratings up to 90 l/min [24 US gal/min], pressure ratings up to 450 bar [6,500 psi], and many sizes to choose from, shuttle valves can be used in a variety of ways, from load sensing to loop flushing.
Relief valves are used as pressure-limiting devices to protect hydraulic systems and components. With flow ratings up to 380 l/min [100 US gal/min] and pressure ratings up to 400 bar [5,800 psi], our relief valves are available in various types, including direct-acting, differential-area, pilot-operated, bi-directional, and cross-over HIC.
Pressure-reducing valves limit pressure in one portion of a circuit while leaving system pressure unaffected. With flow ratings up to 300 l/min [80 US gal/min] and pressure ratings up to 350 bar [5,075 psi], they are available in direct-acting and pilot-operated types and as pressure reducing/relieving valves or as pressure reducing valves only.
Sequence and unloading valves
Sequence valves control a sequence of operations, usually using a pressure signal to shift a spool, thereby opening or closing a flow path at a pre-set pressure. With flow ratings up to 250 l/min [60 US gal/min] and pressure ratings up to 350 bar [5,000 psi], our sequence valves include direct-acting, pilot-operated, kick-down, and unloading valves. Our range of sequence valves can help control function timing and improve efficiency.
Flow control valves
Flow control valves, which limit or regulate flow, are available in three basic cartridge types: restrictive-type, priority-type, and divider/combiner type. Flow ratings are available up to 380 l/min [100 US gal/min] and pressure ratings up to 450 bar [6,500 psi]. Combination valves in manifolds for additional features such as fully adjustable flow or free reverse flow are also available.
Directional control valves
Our full line of directional control valves offers both manual and hydraulic actuation options. With flow ratings up to 265 l/min [70 gal/min] and pressure ratings up to 450 bar [6,500 psi], multiple schematic types and valve sizes are available to meet your circuit needs. Hydraulically actuated spool valves are available as 2-way (normally open or normally closed), 3-way, and 4-way valves, and are used for direction control. These are all 2-position valves that are spring-biased to a neutral position and use hydraulic pressure of 3 bar to 10 bar [40 psi to 150 psi] to shift the spool.
Logic element valves
Logic elements are multi-purpose devices that, when used with other cartridge valves, can create a wide variety of circuits for control of pressure, flow, and direction. Flow ratings are available up to 400 l/min [100 US gal/min] and pressure ratings up to 350 bar [5,000 psi]. Common applications include load-sensing for a fixed-displacement pump and bypass-type pressure-compensated flow control.
Motion control valves
Overcenter and motion control valves provide static and dynamic control of loads by regulating the flow into and out of hydraulic actuators. With pressure ratings up to 430 bar [6,200 psi] and flow ratings up to 300 l/min [80 US gal/min], these valves can improve machine stability and efficiency while eliminating valve noise. They can also stop runaway loads in the event of a hose burst.
Solenoid valves are electrically-operated, on-off poppet or spool-type valves for load holding, blocking, or directional control applications. Our solenoid valves offer a wide range of schematic options in both standard and high-pressure models. With flow ratings up to 227 l/min [60 US gal/min] and pressure ratings up to 350 bar [5,000 psi], over 100 models are available. Various combinations of position/porting can be arranged (e.g., from 2/2 to 3/5).
Our proportional valves offer a wide range of schematic options, including pressure control, flow control, and directional control. With flow ratings up to 180 l/min [48 US gal/min] and pressure ratings up to 350 bar [5,000 psi], various sizes are available to provide the correct product for each application. Proportional valves come in a wide variety of styles and options, including: bi-directional or uni-directional, poppet and spool, normally closed or open, pressure reducing, pressure relieving, and flow control.
Coils and electronics
Danfoss offers both standard and robust coils. All Danfoss coils are offered in a variety of sizes, DC and AC voltages, environmental protection, and connectors to meet any application need. Robust coils are specifically designed for harsh operating environments, with high tolerances to temperature extremes, voltage spikes, and water exposure. Typical applications include asphalt machinery, agricultural equipment, snowplows, marine equipment, salt-spreader machines, or any application when applying the valves in a hot engine compartment.
