Compensated directional control valves
Our compensated directional control valves are continuously stackable and can be seamlessly combined using a modular approach. With valve sizes ranging from 65 l/min to 500 l/min [17 US gal/min to 132 US gal/min], the portfolio offers an almost infinite number of components and configurations to provide smooth and consistent machine control that meets your requirements. From open-center mechanical options to compensated CAN-bus-controlled variants, we have solutions for all types of off-highway applications.
Features and benefits
- Multiple modules and options available in each valve group
- Stackable with up to 14 independent sections
- Possible combination with the rest of the spool valve portfolio, using interface modules
- Load-independent flow control
- Reliable regulation characteristics across the entire flow range
- Load sense relief valves for A and B port enables reduced energy loss at target pressure
- Compact design, easy installation and serviceability

Inlet modules
Inlet modules, also referred to as proportional valve pump side modules, act as interfaces between the proportional valve group and the hydraulic pump and reservoir. An open-center inlet is used for a fixed-displacement gear pump, and a closed-center inlet is used for an open-circuit axial piston pump.
Work modules
A proportional valve basic (PVB) module, also known as a work section, is the interface between a proportional valve group and a work function such as a cylinder or motor. Each PVB has built-in work-section control functionality, and we have products to accommodate a wide range of flows from simple non-compensated to load-independent, meter-in compensated.
Spools
When a work function such as a cylinder or motor is connected to a work section, a spool can be used to change its speed (by adjusting flow) or its power output (by adjusting pressure buildup). A spool is chosen to match a work section's activation method, and each is equipped with a spring that returns it to a neutral position when power is disrupted.
Electrical actuation
Our proportional-valve electro-hydraulic actuators provide fast, accurate, and reliable valve operation under varying conditions. We offer a wide variety of speed and hysteresis capabilities to precisely suit your application needs, and all actuators are designed to plug and perform with our PLUS+1® joysticks and controllers.
