Quality and compliance are the foundation of long-term water supply projects. Tianjin Runke Plastic Tech. Co., Ltd. manufactures UPVC / PVC-U valves and fittings under a documented quality management system, and holds an Environmental Management System certificate (ISO 14001:2015 / GB/T 24001-2016) covering the manufacture of plastic pipe fittings (PVC, PE), as shown below.
Quality Control at Every Step
Raw material inspection — every batch of PVC-U compound and rubber seals is checked for composition and performance before entering production.
In-process control — dimensional and appearance checks follow DIN, ANSI and JIS standard requirements for each valve series.
100% pressure testing — each valve is tested at our in-house test bench before packing; test records are kept for traceability.
Documents on request — certificates, material declarations and test reports can be provided with your shipment or for tender submission.
Need specific certificates or a third-party inspection report for your project tender? Contact us and we will send them within 24 hours.
