China is the world’s largest exporter of valves, shipping over $20.5 billion worth in 2023. Many Chinese rising stem gate valve manufacturers have modern facilities and international certifications (API, ISO, CE) to serve global markets. This 2025 guide ranks the top 8 China rising stem gate valve manufacturers. We highlight each company’s strengths—from materials and pressure ratings to export capabilities—so you can find the best fit for your needs.

What Is a Rising Stem Gate Valve?

A rising stem gate valve is designed so that the stem visibly moves up when the valve opens, helping operators easily see the valve’s status.

Key Takeaways:

• The stem moves with the gate, making valve status visible from a distance.
• Ideal for high-pressure and high-temperature pipelines.
• Common in waterworks, oil, gas, and chemical plants.
