Import Concentric Butterfly Valves — Buy in wholesale FOB from Supplier in China

Bonny Valve Co., Ltd. manufactures concentric butterfly valves with a size range from 2 to 80 inches (DN50 to DN2000), designed for low-pressure flow control in industrial and municipal systems. The valves feature a centered stem and resilient seat, with the disc rotating 90 degrees to open or close the flow path, and include an optional disc locking device for added security. These valves are built to API 609 and ASME B16.10 standards, ensuring consistent face-to-face dimensions and interchangeability with other compliant components.

The valves are constructed from a broad selection of materials, including cast iron, ductile iron, carbon steel, stainless steel, duplex stainless steel, super duplex stainless steel, nickel alloys, nickel aluminum bronze, Hastelloy, and Inconel. Seat materials include EPDM, NBR, and PTFE, while end connections are available in wafer, lugged, flanged RF, RTJ, and FF configurations. Actuation options include lever and gear operation, with the design optimized for applications in water, chemical, and oil industries where reliable shut-off and minimal flow resistance are critical.

Engineering contractors and industrial buyers source these valves for use in water distribution, wastewater treatment, and fire protection systems, as well as chemical and oil processing plants. The concentric design’s simplicity and compactness make it a cost-effective solution for large-diameter pipelines, where space and weight constraints are a concern. Buyers should confirm the valve’s pressure rating, temperature limits, and material compatibility with their specific media, as well as the appropriate end connection and actuation method for their system requirements.

Bonny Valve Co., Ltd. is based in Unit No. 130, Dong’ou Industrial District, Wenzhou, Zhejiang, China. The company operates under the harbor trust tier, indicating a verified presence in the industrial valve manufacturing sector. With a focus on concentric butterfly valves, Bonny Valve leverages its experience to serve global markets, particularly in Asia, where demand for cost-effective, standard-compliant flow control solutions is high.

The supplier’s profile highlights its specialization in manufacturing valves for diverse industries, including water, chemical, and oil sectors. While the listing does not provide details on certifications, production capacity, or client references, it emphasizes compliance with international standards such as API 609 and ASME B16.10.
