1. From R&D to delivery, we have a very strict management system.
2. Our products are designed, molded, and produced in accordance with international standards. Quality control mainly includes inspection in first-piece, process, packaging, and finished product. Only products that pass the inspection can be packaged.
3. Not only do we have our own CNAS laboratory for testing, but every year we also send samples to authoritative certification institutions to ensure long-term product quality. For example, our star product - PVC ball valve, has passed physical tests such as high temperature resistance, corrosion resistance, impact resistance, and chemical tests.
4. Our products have different connection methods, including glue bonding, hot melting, electric melting, and thread, which can meet different needs.
5. Accessories such as rubber rings and glue used for connections are also produced by us and undergo relevant inspections to ensure high quality.
