This offers unparalleled flexibility, as cartridge valves can be sized, tuned, and adjusted to match individual flow requirements in a single package. Although cartridge valves are installed in a centralized manifold, each valve can be fine-tuned independently, making it possible to optimize the meter-in/meter-out performance of one function without adversely affecting the other functions in the circuit. The result is less wasted energy in the form of pressure drop and improved metering and flow control.Ĭartridge valve-based directional control circuits are a superior alternative for controlling the motion of a hydraulic cylinder or motor. This allows the machine to be more productive and efficient by providing separate and independent meter-in/meter-out performance. However, a traditional spool valve constrains design engineers to use fixed meter-in/meter-out characteristics while the use of multiple cartridge valves does not. Traditionally, flow sharing circuits are achieved using spool-type directional control valves. Post-pressure compensation allows available pump flow to be evenly distributed among all of the operating functions, even when total flow demand exceeds available pump supply, and work functions are at dissimilar working pressures.įlow sharing is desirable whenever a machine needs to operate multiple work functions simultaneously.
Multi-function valves, upgraded hydraulic circuit design software and engineered hydraulic control solutions that eliminate guesswork are just a few ways to streamline the process of designing hydraulic controls for mobile equipment.
