On January 16th, Lanzhou Petrochemical Company's Machinery Factory announced a significant breakthrough. The factory successfully completed the hot-state testing of its large-diameter, three-eccentric, hard-sealed, high-temperature butterfly valve under real industrial conditions. All performance parameters met or exceeded the design specifications, marking a major milestone in the development of this independently innovated valve. Equipped with two proprietary technologies, this product is now ready for market entry. The successful test not only confirms the technical reliability of the valve but also highlights the factory's growing capabilities in advanced valve manufacturing. This achievement represents a key step forward in China's efforts to develop high-performance, domestically produced industrial equipment. The valve is expected to be widely used in petrochemical and energy sectors, offering a reliable and efficient solution for high-temperature and high-pressure environments. With this success, the factory is well-positioned to compete in both domestic and international markets.

Electric Cylinder

Electric cylinders, also known as electric actuators, use various electric motors (such as electric servo motors and stepper motors) to drive various screws (such as sliding screws and ball screws) to rotate. Due to its closed-loop servo control, low maintenance cost,and flexible configuration,electric cylinders are now widely used in entertainment industries,military industries, automotiveindustries, mechanical processing, and medical equipment that require precision control.

DGR Servo electric cylinder is self-developed by our research and development team, which enjoys high reputation in domestic and outboard machnery market. Our products include servo/stepper motor electric cylinders, linear actuators, multi-degree of freedom platforms, synchronization lifting platforms,VR simulators
