Presenting our groundbreaking HLPSL and HLPSV load-sensitive proportional multi-way directional spool valves. These revolutionary engineering marvels seamlessly integrate pressure, flow, and directional control into a single, harmonious unit, ensuring unparalleled performance and reliability. Comprising three essential functional modules - connecting blocks, directional valves, and end plates - these valves are meticulously crafted for high-end hydraulic systems, pivotal in top-tier engineering machinery. They precisely govern the movement direction and speed of hydraulic cylinders, motors, and other actuators, delivering unmatched precision and control. Key highlights include a compact structure, superior energy efficiency, and stepless speed control. Additionally, they enable multiple actuators to operate simultaneously under varying loads, offering unrivaled performance and versatility for any application.
The HLPSL valves are expertly tailored for constant displacement pump systems, ensuring steadfast and reliable operation. Conversely, the HLPSV valves are masterfully engineered for variable pump systems. While HLPSV valves may exhibit a slightly slower response time, they excel in delivering exceptional energy-saving performance, making them the ultimate choice for applications where efficiency is paramount. With their state-of-the-art engineering and energy-efficient design, HLPSV valves emerge as the premier solution for advanced hydraulic control requirements.
