R&D Center
Shangtie Valve has always adhered to the core concept of "technology-driven, quality-based", integrating R&D innovation, refined production and strict quality control into the whole industrial chain. We are committed to providing global customers with safe, reliable and high-performance industrial valve solutions, and demonstrating our strong strength in R&D and manufacturing through professional technology, advanced equipment and standardized management.

R&D Center

As a technology-oriented enterprise, Shangtie Valve focuses on independent R&D and technological innovation, and has built a professional R&D team composed of senior engineers with rich experience in fluid control, material science and high-temperature and high-pressure valve design. We continuously increase R&D investment, equip advanced R&D equipment and digital design software, and establish close technical cooperation with research institutions to form a complete R&D system covering product design, structural simulation, performance optimization and new technology exploration.

Our R&D work adheres to international standards such as API, ANSI, GB and ASME, and focuses on solving the pain points of industrial valve application in harsh working conditions. We are committed to the research and development of high-performance, energy-saving and environmentally friendly valve products, focusing on the application of new materials, optimization of sealing technology and upgrading of intelligent control, and have obtained a number of practical patents and technical achievements. Whether it is customized product development for special working conditions or performance improvement of standard products, we can quickly respond to customer needs and provide professional technical solutions.

Manufacturing

Shangtie Valve has a large modern production base, equipped with standardized workshops, advanced CNC machining centers, precision forging equipment and complete assembly lines, forming a systematic production system from raw material processing, forging, precision machining, heat treatment to finished product assembly. Our production scale covers a full range of valve products with sizes from NPS1/2" to NPS60" (DN15mm to DN1500mm) and pressure classes from Class150LB to Class2500LB (PN10 to PN420), which can stably meet the needs of mass production and customized orders.

We adopt lean production management mode, and implement standardized operation in every production link to ensure high production efficiency, stable product quality and on-time delivery. Our skilled technical workers have rich production experience, and strictly implement production processes and technical standards to ensure that each valve component meets the precision requirements. At the same time, we continuously optimize the production process, introduce intelligent production equipment, improve production automation, and realize the organic combination of scale production and refined manufacturing.

QC

Quality is the foundation of Shangtie Valve's development. We implement a full-chain quality control system covering raw material inspection, production process monitoring, finished product testing and after-sales tracking, and strictly implement international quality standards such as ISO 9001, API 598 and ISO 5208 to ensure that every valve leaving the factory meets the highest quality requirements.

In the raw material link, we conduct strict incoming inspection on all raw materials, including chemical composition analysis, mechanical performance testing and material certification verification, to ensure that the raw materials meet the standard requirements. In the production process, we set up multiple quality inspection points, monitor the processing precision, heat treatment effect and assembly quality in real time, and eliminate unqualified products in the bud. In the finished product testing link, we carry out strict pressure test, sealing test, hardness test, low leakage detection and other items, and issue test reports for each product to ensure the reliability and safety of the product.

In addition, we have a professional quality inspection team with rich industry experience, equipped with advanced testing equipment comparable to third-party professional facilities, which can carry out various professional tests to meet the quality verification needs of different industries and working conditions. We also welcome third-party testing to further ensure product quality and win the trust of global customers with transparent and strict quality control.
