ZDFM7-22 Integrated LUDV Multi-way Valve: Available in both integrated configurations (3-section and 5-section) and modular single-section designs, enabling flexible combinations according to actual operating conditions. Equipped with an LUDV (Load-Independent Flow Distribution) system, it proportionally reduces the operating speeds of all actuators when system flow is insufficient—i.e., when the hydraulic pump cannot supply sufficient flow to operate all actuators at their required speeds—thereby preventing any actuator from stopping due to inadequate oil supply.
