OEM / ODM Request Is Very Welcome!

Production Process
The castings of valve cover are manufactured by automatic production line, with shell moulding cores. Thus, the large-scale, elaborate and high quality production is realized. Then through efficient machining and rigorous inspection, OEM valve series products would be eventually obtained with good surface quality, high dimensional accuracy, precise weight and optimal comprehensive performance cost ratio.

Before product development, we will evaluate and highlight the technical requirements of the gate valve body, including: material, surface treatment, hardness, weight, important technical requests and customer's special requests. Meanwhile, we will establish files for each customer, including: technical documents, communication records and the time of technique requests changes, this will help us to provide guarantee for product inspection.

Inspection

We have complete testing instruments and quality control means, thus we can control the quality of products from raw materials to finished products timely and effectively. Our commonly used inspection equipment includes: Spectral analyzer, Tensile tester, Hardness tester, Microscope, Roughness tester, CMM, Projector and other gauges and tools.
