When a paint line is switching colors hundreds of times a day, the color change valve is doing most of the work. Seal failure, slow response, or poor purge performance doesn’t just affect one part — it stops the entire line.

We manufacture color change valves in-house at our facility in Chongqing, China. Every component that matters — valve seats, seals, actuation parts — is produced by our own team, not sourced from third-party suppliers.

Here is what our color change valves deliver:

Cycle lifespan of over 2.5 million operations. This is based on real production conditions, not lab testing.

Support for 12 to 24 color configurations within a single manifold block. The system scales without requiring a full redesign.

Full compatibility with both waterborne and solvent-borne paint systems. Seal materials are selected for the specific coating environment.

Response time under 80 milliseconds, allowing fast color changeover without compromising purge quality.

Direct replacement available for Nordson, Ransburg, and Sames color change valve systems. Most spare parts ship from stock.

We have been supplying color change systems to Changan Automobile, Ford, and Tier-1 automotive suppliers for over 20 years. That record is the result of consistent product quality and reliable delivery — not marketing.

If you are sourcing color change valves for a new line, looking to reduce spare parts costs on existing equipment, or evaluating alternatives to imported systems, we are ready to discuss your requirements.

Send a message with your application details or part numbers. We will respond with specifications and pricing within 24 hours.
