Import Flange Plastic Ball Valve — Buy in Bulk from Supplier in China

Flange plastic ball valves from Yongjia Goole Valve Co., Ltd. are designed for low-pressure fluid control in corrosive environments. These valves operate within a pressure range of 0.6 MPa to 1.2 MPa and are available in nominal diameters from 15mm to 300mm. The body and ball are constructed from reinforced polypropylene (PP) or polyvinyl chloride (PVC), with flanges matching ANSI 150 lb or DIN PN10 standards. The ball is polished and seated with PTFE or EPDM seals to ensure bubble-tight shut-off.

The valve body materials are selected for chemical resistance, making them suitable for handling acids, alkalis, and wastewater. PP offers higher temperature tolerance up to 90°C, while PVC is limited to 60°C. The flange faces are integrated into the body via molding, eliminating gasket leakage points. These are not designed for high-pressure steam, gas, or abrasive slurries. The actuation is manual via lever or gear operator, with no automated options listed.

These valves are commonly purchased by water treatment plants, chemical processing facilities, and HVAC contractors managing non-potable fluids. Buyers typically require documentation on material composition and pressure testing. Packaging is in cartons with foam inserts, with 5 to 20 units per box depending on size. Trade terms are FOB Ningbo, with lead times of 20 to 30 days. MOQ is typically 10 units per size, but bulk discounts apply for orders over 100 units.

Yongjia Goole Valve Co., Ltd. is located in the He-Yi Industrial Zone, Oubei Town, Wenzhou, Zhejiang, China, a region known for plastic valve manufacturing. The company specializes in injection-molded and assembled plastic valves, with production focused on cost-effective, non-metallic solutions. The listing does not state company age, workforce size, or export history. No certifications such as ISO or CE are mentioned, but the use of standardized pressure ratings suggests baseline production capability.

There is no information on quality control procedures, material sourcing, or third-party testing. The supplier does not provide response metrics, indicating limited buyer engagement. Buyers should request material certificates for PP or PVC used, as recycled content may affect performance. The company appears to serve distributors and OEMs requiring bulk quantities rather than custom-engineered solutions.
