PSL Proportional Multiway Directional Valves
Product Overview
PSL Proportional Multiway Directional Valves are high‑grade modular Hydraulic valve designed for mobile machinery. It serves as the central control unit of the complete hydraulic system, precisely regulating flow rate, oil direction and working pressure for multiple actuators on the Machine[(HAWE Hydra...)]. Featuring load‑sensing modular sectional structure, this valve bank supports manual, hydraulic pilot, electro‑proportional and CAN‑bus control modes. Multiple valve sections can be freely combined according to equipment requirements, simplifying piping layout and improving the integration level of the whole hydraulic circuit[(HAWE Oil-H...)].

Working Principle
This core Hydraulic valve adopts load‑sensing pressure‑compensated spool structure inside the valve sections. Within the hydraulic system, it continuously adjusts spool opening according to control input signals. It steers oil flow direction and realizes stepless speed adjustment for hydraulic cylinders and hydraulic motors on the Machine.
Independent pressure compensator for each valve section keeps stable output flow even under varying load conditions. Multiple executive components can run simultaneously without mutual interference. The built‑in load‑sensing feedback signal transmits actual working pressure back to the oil‑supply pump, achieving energy‑saving matching of pump output and actual load demand. Integrated over‑pressure protection prevents component damage caused by system over‑pressure.
Key Advantages
1. Modular sectional design; valve quantity and auxiliary functions can be freely configured to match different Machine working requirements.
2. Excellent load‑sensing pressure compensation performance; stable speed output regardless of load fluctuation in the hydraulic system.
3. Diverse control selections: manual, pilot hydraulic, proportional electric and CAN‑bus communication for intelligent automatic operation.
4. High control precision, low hysteresis, smooth action; avoids impact during machinery startup and switching.
5. Good anti‑pollution capability, robust structure, reliable for heavy‑duty mobile working environment; convenient for sectional inspection and replacement.
Application Scope
This premium Hydraulic valve is widely equipped in the hydraulic system of various Machine: truck‑mounted cranes, mobile cranes, aerial work platforms, concrete pump trucks, forestry machinery, sanitation vehicles, special engineering equipment and mobile industrial devices. Mainly used for lifting, slewing, travelling, telescopic and clamping action control of multi‑function mobile machinery
