PSV Proportional Multiway Directional Valves
Product Overview
PSV Proportional Multiway Directional Valves are high‑performance modular Hydraulic valve, specially developed for variable‑pump hydraulic system. As the central control component, it precisely governs oil flow, direction and operating pressure for multiple actuators on the Machine. Adopting load‑sensing sectional combinable design, this valve supports manual operation, hydraulic pilot control, electro‑proportional drive and CAN‑bus signal control. Different valve sections can be freely assembled according to working conditions, optimizing pipeline layout and improving overall energy‑saving efficiency of the hydraulic circuit .

Working Principle
This key Hydraulic valve is built with load‑sensing pressure‑compensated spool structure. Inside the hydraulic system, it receives control commands to adjust the opening degree of each spool, thereby changing oil flow path and realizing stepless speed regulation for hydraulic cylinders and hydraulic motors fitted on the Machine .
Each valve section is equipped with an independent pressure compensator to keep stable flow output despite changing external load. The load‑sensing signal feeds actual working pressure back to the variable pump, so the pump automatically adjusts displacement to match real‑time load demand and reduce energy loss and oil heating. Multiple actuators can run simultaneously without mutual interference. Built‑in over‑pressure protection safeguards the whole Machine against pressure overload damage.
Key Advantages
1. Modular sectional construction; valve quantity and auxiliary functions are configurable to satisfy diverse Machine working conditions.
2. Optimized for variable‑pump hydraulic system. Excellent load‑sensing function delivers remarkable energy‑saving performance and reduces system heat generation .
3. Rich control options: manual, hydraulic pilot, electro‑proportional and CAN‑bus communication, suitable for intelligent automatic equipment.
4. High proportional control accuracy, low hysteresis, smooth switching action, effectively avoids mechanical impact during startup and direction change.
5. Robust mechanical structure, good anti‑pollution performance, adapts to harsh mobile‑machinery environments; single valve section can be inspected or replaced without disassembling the complete valve bank.
Application Scope
This premium Hydraulic valve is widely integrated into the hydraulic system of various Machine: truck‑mounted cranes, mobile lifting equipment, aerial work platforms, drilling rigs, forestry machinery, municipal sanitation vehicles and special engineering machinery. It is used for multi‑action control including lifting, slewing, telescoping, travelling and clamping for complex mobile equipment[(HAWE Hydra...)].
