Import Astm A216 Wcb Rotary Valve, Dn80, Pn10 — Buy in wholesale FOB from Supplier in China

The ASTM A216 WCB Rotary Valve, DN80, PN10 from China Vervo Valve Manufacturer Co. Ltd. is a carbon steel rotary valve built to ASTM A216 material standards with a nominal diameter of 80 mm and pressure rating of PN10 (1.0 MPa). The WCB grade indicates wrought carbon steel suitable for elevated temperature service, cast to provide the mechanical properties defined in the ASTM specification. This particular configuration suits medium-pressure fluid control in pipelines where quarter-turn operation and reliable shut-off are required.

ASTM A216 WCB is a standard cast carbon steel grade with typical composition limits of 0.30% carbon maximum, 1.00% manganese maximum, and 0.60% silicon maximum, with residual elements controlled per the specification. The PN10 rating denotes nominal pressure of 10 bar, typical for water, oil and gas applications in European and Asian pipeline standards. The rotary valve design employs a rotating closure member, usually a ball, plug or butterfly disc, achieving full bore flow with minimal pressure drop when open and tight sealing when closed. Standard face-to-face dimensions for DN80 valves follow EN 558 or ISO 5752 series, though buyers should confirm exact dimensions against their piping layout.

This valve serves oil and gas distribution, chemical processing plants, water treatment facilities and power generation systems where carbon steel compatibility and PN10 pressure class are appropriate. Typical buyers include EPC contractors, system integrators and maintenance procurement teams sourcing for fluid handling projects. The supplier lists Zhejiang province as its location, a region with established valve manufacturing clusters. Buyers should confirm pressure-temperature ratings, end connection details (flanged, threaded or wafer), actuator mounting provisions and any required third-party inspection with the supplier directly.

China Vervo Valve Manufacturer Co. Ltd. is located in Lishui, Zhejiang Province, China, with its registered address at No.1 Building, Wanyang Zhongchuang, Bihu. Zhejiang represents one of China's principal valve manufacturing regions, with concentrated supply chains for casting, machining and assembly operations serving domestic and export markets. The supplier carries a harbor trust tier classification, and the available profile records a 0.00% response rate with zero average response hours, indicating no verified response data is currently available through the platform.

The listing presents this company as a manufacturer of the ASTM A216 WCB rotary valve, though the profile does not disclose year of establishment, factory size, annual output, workforce numbers, or specific quality system certifications held. No client references, export markets served, or in-house testing capabilities are stated. Buyers should conduct direct due diligence to verify manufacturing scope, quality management system certification (ISO 9001, API Q1), and any API monogram or CE marking authorisation the supplier may hold. The absence of verified response metrics suggests proactive outreach and reference checks are essential before commitment.
