Directional Spool Valves

These directional seat valve blocks are supplied as aluminium monoblocks with a maximum of 5 actuator ports. These valve blocks are used in all situations where the actuator – either single- or double acting – must provide the highest levels of leak-tightness.

Series HDM directional control valves feature compact, cast monoblock bodies and have high operating pressure ratings.

Available in 9 different sizes, the large range of spools, spool operators, levers and auxiliary shock/anti-cavitation valves make the HDM series especially suitable for use in medium-complexity circuits. They are also very suitable for straight-forward applications in which a particularly small overall size is required.

The HDM series is available in the following versions: open centre, parallel/series, closed centre and carry-over.

A further notable feature is the very low level of internal spool leakage.

This range of proportional valves is used to provide load-independent speed control of motors and cylinders.

CV (Compac) means: all valves functions are integrated into one compact block.

This range of proportional valves is used to provide load-independent speed control of motors and cylinders.

The L.8S valve series covers an actuator flow rate of up to 90 l/min and was developed for mobile applications. The valves are particularly characterized by their robust design and small external dimensions, and they offer a wide variety of additional functions that can be integrated. The L.8S is a flexible modular system whose elements can be combined to form a valve block that complies fully with the requirements of the application. The valve blocks can be configured for fixed-displacement or load-sensing pump systems as well as for systems that can switch between either type of supply.

Series LCV proportional directional control valves have been developed for use in tractors and similar applications. The high level of integrated functionality combined with the ability to parametrize the valve characteristics provide the basis for enhanced system solutions. The outstanding dynamics and stiffness of the valve’s stepper-motor operation ensure first-rate control of the actuators. Flexibility within the sections themselves, and supplementary functions in bolt-on plates, open the door to optimized solutions. The fully automated high-volume production guarantees extremely high quality at very attractive terms. Achieve maximum productivity with reduced energy consumption.

The design uses the concept of pressure compensators integrated in the control spool to achieve very low pressure loss. This feature, together with the downstream system for flexible parallel actuation and the high degree of modularity, makes this proportional directional valve suitable for very adaptable application in mobile machines. The additional functions that can be incorporated, the high power density combined with high actuator flow rates of up to 180 L/min and the possibility of combining two different valve sizes in one control block round off the LVS08 / LVS12 proportional directional valves. They make up a flexible and compact modular valve system.

The valve blocks can be configured for fixed-displacement or load-sensing pump systems.

This range of proportional valves is used to provide load-independent speed control of motors and cylinders. The LVS18 is operating according to the flow sharing principle. Also available with rapid-traverse and floading function.
