Multi-way directional control valves—TY-PSL for fixed-displacement pump systems and TY-PSV for variable-displacement pump systems—enable load-independent (pre-compensated) and infinitely variable speed control of hydraulic actuators. Multiple actuators can operate simultaneously and independently of one another. These valves are primarily used in mobile hydraulic machinery (e.g., crane control systems). Optimal matching to diverse control tasks is achieved by selecting different maximum flow rates at actuator ports A and B, as well as by choosing various optional functions (e.g., secondary pressure limiting, function shutoff) integrated within the base block, intermediate plate, or add-on blocks.
