Yangzhou, April 17, 2026 — Jiangsu KM Hydraulic Control System Co., Ltd. (KM Hydraulic), a leading high-end hydraulic component manufacturer in China, has been highly recognized by global customers for its precision manufacturing capabilities and stable product quality. What distinguishes KM from other manufacturers is its unique competitive advantage — independently R&D and manufactured test benches, which build an unbreakable barrier for product quality and become a core symbol of the company’s strength in the hydraulic industry.
Precision Manufacturing: The Foundation of Stable Quality
As a national high-tech enterprise and a "Little Giant" enterprise specializing in hydraulic components, Jiangsu KM has always regarded precision manufacturing as the core of its development. The company has built a 5,000-square-meter intelligent and clean production workshop, equipped with imported high-precision machining centers, CNC honing machines and three-coordinate measuring instruments, forming a full-process precision control system from raw material processing to finished product assembly.
Focusing on the production of load-sensing proportional multi-way valves, KM strictly controls every key process: the matching gap of core components is controlled within 0.005mm, the surface roughness of the valve internal flow channel reaches Ra≤0.2μm, and the dimensional tolerance of key parts complies with IT7 level standards, ensuring the high precision and consistency of each product. With the support of intelligent compensation technology, the company realizes that the precision attenuation rate of 24-hour continuous processing is ≤0.002mm, and the qualified rate of key dimensions reaches 100%, laying a solid foundation for the stable operation of products in harsh working conditions such as vibration, dust and high pressure.
Core Differentiation: Self-Developed Test Benches, Exclusive Quality Guarantee
Unlike most hydraulic manufacturers that rely on external test equipment or purchased test benches, Jiangsu KM has independently developed and manufactured a full set of professional hydraulic valve test benches, which is a key highlight that distinguishes KM from other factories and a core guarantee for product quality stability.
The self-developed test benches by KM are customized according to the performance characteristics of load-sensing proportional multi-way valves, integrating multiple test functions such as shell pressure test, high and low pressure seal test, flow characteristic test, response time test and fatigue cycle test, fully complying with JB/T 10674-2022 standards. Equipped with high-precision sensors and independent R&D measurement and control software, the test benches can accurately measure key parameters such as pressure, flow and valve core displacement, automatically record test data and generate professional test reports, realizing the full-process traceability of product testing.
Compared with purchased test benches, KM’s self-developed test benches have stronger pertinence and flexibility: they can be quickly adjusted according to the customized needs of different products and customers, simulate the actual working conditions of construction machinery and agricultural machinery more accurately, and detect potential quality risks in advance that may be ignored by ordinary test equipment. This unique advantage enables KM’s load-sensing proportional multi-way valves to maintain stable performance in long-term operation, with a failure rate lower than 0.1%, far exceeding the industry average.
Strict Quality Control: From Production to Delivery, Zero Compromise
With precision manufacturing as the foundation and self-developed test benches as the core, Jiangsu KM has built a three-level quality control system covering raw material inspection, in-process testing and finished product inspection. Every batch of raw materials must pass strict chemical composition and mechanical performance testing before entering the factory; in the production process, online detection equipment is used to conduct real-time inspection of key dimensions and processing accuracy; before delivery, each product must go through 100% full-performance testing on the self-developed test bench, including 10,000 times of opening and closing cycle tests, to ensure that it meets the design requirements and customer needs.
In addition, the company has established a complete quality management system, passed ISO9001 international quality certification and CE certification, and implemented full-process quality traceability, ensuring that every product delivered to customers is reliable, stable and high-performance.
Customer Recognition: Stable Quality Wins Global Trust
Relying on its outstanding precision manufacturing capabilities and the unique advantage of self-developed test benches, KM’s load-sensing proportional multi-way valves have been widely used in construction machinery, agricultural machinery, special vehicles and other fields, and exported to Europe, Oceania, Southeast Asia and other international markets. It has become a core supplier of many well-known host manufacturers, winning unanimous recognition from customers for its stable product performance, long service life and reliable quality.
Future Outlook: Deepen Precision Manufacturing and Lead Quality Upgrade
In the future, Jiangsu KM will continue to focus on the field of precision hydraulic components, continuously upgrade its precision manufacturing technology, optimize the performance of self-developed test benches, and further improve the stability and reliability of products. With the concept of "quality first, innovation-driven", the company will continue to play the advantage of self-developed test benches, break through technical bottlenecks, provide more high-quality, stable and reliable hydraulic solutions for global customers, and strive to become a world-class precision hydraulic component manufacturer.
