The HD-4WRLE-4X/series is a pilot-operated high-frequency response directional control valve that integrates electrical position feedback with on-board electronics (OBE). It features fast response, high control accuracy, and a fail-safe position in the event of power loss. The on-board electronics precisely adjust the positions of both the pilot and main control valve spools, enabling accurate position, velocity, and pressure control under high pressure and large flow conditions, ensuring stable and efficient system operation. This product is widely used in various industries such as industrial automation, metallurgy, and plastic machinery, thanks to its excellent high-response and high-precision performance.
