Import Astm Cf8 Soft Seal Flange Butterfly Valve — Buy in wholesale FOB from Supplier in China

The ASTM Cf8 soft seal flange butterfly valve is a flange-connected, lug-type valve designed for flow control in water, oil, gas, steam, and corrosive media systems. This model supports a size range of DN15 to DN2000 and pressure ratings of PN10, PN16, PN25, and PN40, with a body constructed from carbon steel (WCB/A105/Q235), stainless steel (304/304L/316/316L), or alloy steel (20#/cast iron/ductile iron). The disc is available in 304/304L/316/316L or ductile iron, paired with a stem in stainless steel 304/304L/316/316L, ensuring compatibility with aggressive fluids and high-temperature applications.

Seal materials include PTFE, HDPE, EPDM, NBR, Viton, or nylon, with O-ring options in NBR, EPDM, Viton, or HNBR/HSN, providing flexibility for chemical resistance and temperature tolerances. The valve undergoes pre-delivery testing, including strength and enclosure tests, to confirm leak-proof performance under rated conditions. Typical industry standards for such valves include ASTM A216 for carbon steel castings, ASTM A351 for CF8 stainless steel, and API 598 for pressure testing, though these are not explicitly stated in the supplier’s profile.

Common applications span water treatment, chemical processing, waste effluent systems, paper manufacturing, construction, drilling, and compressed air or gas plants. The valve’s wafer or flange design allows for easy installation between flanges, reducing pipeline weight and space requirements. Buyers typically verify pressure class suitability for their system, confirm material compatibility with the media, and specify seat material based on temperature and chemical exposure. The supplier’s annual capacity of 20,000 tons supports large-scale orders, with packaging in wooden boxes and plastic film to prevent damage during transit.

Baoding Valvula Imp & Exp Trading Co. Ltd. is based in Baoding, Hebei, China, with its registered address at Lvdu Huangcheng, Longxing Middle Road. The company operates in the harbor trust tier, indicating a verified presence in the industrial valve supply chain. Its product portfolio includes ANSI, DIN, and GOST gate valves, soft sealing gate valves, knife gate valves, and flat gate valves, alongside a range of butterfly valves such as wafer type, single eccentric, double eccentric, and three eccentric designs.

The supplier also manufactures check valves, ball valves, and strainers, with materials spanning WCB, Q235, ST37, LBC/LCC, WC6/WC9, WCC, and stainless steel grades like 304, 304L, 316, and 316L. The company emphasizes OEM services and pre-delivery testing for all valves, ensuring compliance with basic quality checks. However, the profile does not specify certifications beyond ISO 9000, and no response rate or average response time data is available, which may require direct follow-up for trade inquiries.
