Double flange center line butterfly valve

The Double Flange Center Line Butterfly Valve is a pipe‑line component that regulates liquid and gas flow. It is offered in sizes from DN50 up to DN2600, with nominal pressure ratings of PN10 and PN16 and an operating temperature range of - 10 °C to 150 °C. The centre‑line, double‑flange design provides a compact profile while maintaining structural strength for a broad selection of media.

In typical practice the valve body is cast iron and the disc carries a resilient rubber seat, giving a tight shut‑off and low operating torque. Flow resistance is minimised by the streamlined disc geometry and the valve conforms to common standards such as ISO 5211 for mounting and API 609 for performance. The design also allows optional soft‑seat or metal‑seat options depending on the conveyed fluid.

The valve is widely installed in water‑treatment plants, oil‑and‑gas processing units, chemical factories and HVAC distribution networks where precise flow control is required. Plant engineers, EPC contractors and maintenance teams are the principal buyers. The supplier offers flexible minimum order quantities and ships under CIF or FOB terms; ISO and CE certifications are listed in the product data.

Tianjin Zhibang Valve Co., Ltd. is located at Xi Nian Square, Jie Fang Nan Road, Tianjin 300000, China. The company is listed as an imported‑tier supplier and carries a harbour‑level trust tier, indicating that basic verification has been completed by the platform. The response‑rate field shows 0 % and an average response time of zero hours, which suggests that communication may be limited and should be confirmed directly with the supplier before negotiations.

The supplier’s catalogue focuses on industrial valves, including butterfly, gate and ball types, and it can provide units that meet ISO and CE certification requirements. No specific information on production capacity, lead times or minimum order quantities is disclosed in the listing, so those details must be obtained from the supplier during the enquiry stage.
