Sanitary butterfly flange
The sanitary butterfly flange supplied by Wenzhou Zheng Yu Light Industry Machinery Co., Ltd is a hygienic pipe component designed for sterile fluid transfer. It is fabricated from stainless steel 316L (UNS S31603) low‑carbon alloy to support welding and corrosion resistance. Available in nominal diameters from 1 in to 6 in, the flange can be fitted with either tri‑clamp or weld‑neck connections. It carries a pressure rating between 150 psi and 2500 psi, meeting the requirements of sanitary process lines.
The Ra surface finish complies with 3A and ASME BPE sanitary standards, ensuring smooth internal surfaces for clean‑in‑place operations. Typical installations also adopt a Schedule 40 pipe class and a PN 16 flange rating, which align with common European and North American pipelines. The material choice provides resistance to aggressive food‑grade chemicals and repeated sanitisation cycles. Such specifications are standard for equipment used in dairy, beverage and pharmaceutical manufacturing.
Importers targeting food‑processing plants, dairy factories or pharmaceutical fill lines often request these flanges in bulk to match existing pipework. Trade terms are usually negotiated per order, with options for FOB or CIF shipping from ports such as Shanghai or Ningbo. Buyers should confirm the exact MOQ, packaging dimensions and lead time directly with the supplier, as these details are not disclosed in the listing.

Sourcing Sanitary butterfly flange from Wenzhou Zheng Yu Light Industry Machinery Co., Ltd - China Import Guide
Before placing an order, importers should request a detailed product data sheet that lists the exact dimensions, pressure class and connection type for each flange size. Verify that the stainless‑steel grade 316L complies with the 3A and ASME BPE certificates by asking for copies of the test reports. It is also prudent to confirm the supplier’s manufacturing licence and any export licences required for the destination country.
Shipping terms are typically negotiated as FOB from the nearest Chinese port, such as Shanghai, Ningbo or Shenzhen, but buyers may request CIF if preferred. Because the supplier’s response rate is currently zero, agree on a written lead‑time estimate and include milestone dates in the purchase contract. Payment methods often involve a letter of credit or telegraphic transfer; ensure the agreed terms are reflected in the sales agreement to protect both parties.
Given the sanitary nature of the component, a third‑party inspection before loading is advisable, focusing on surface finish, pressure test results and dimensional tolerance. Request an independent mill test report and a certificate of conformity that references the 3A and ASME BPE standards. Retain copies of the inspection report, test certificates and packing list for customs clearance and future quality audits.
