Import Din Lift Check Valve — Buy in Bulk from Supplier in China

The DIN lift check valve from Yuanda Valve Group Co., Ltd. is a cast iron valve designed to prevent backflow in piping systems, complying with DIN 3202-F1 for face-to-face dimensions and DIN 2532/2533 for flange end standards. The body and bonnet are made from GG25 grade cast iron, while the disc combines A105 carbon steel with 2Cr13 stainless steel for strength and corrosion resistance. The seat ring is constructed from stainless steel to ensure a tight seal under pressure.

This valve operates by lifting the disc vertically off the seat when flow proceeds in the forward direction, and it drops back to seal when flow reverses. The disc material combination provides durability in water, steam, and mild industrial fluids. The valve is rated for a nominal pressure of 1.6 bar, with a shell test pressure of 2.4 bar and a seal test pressure of 1.8 bar, as per standard hydraulic testing protocols. It is not intended for high-pressure or abrasive media applications.

Buyers include water treatment plants, HVAC system integrators, and industrial process engineers requiring reliable non-return functionality. The valve is typically ordered in sizes from DN50 to DN200, with flanged ends compatible with DIN standards. Packaging is standard for industrial valves, with protective caps and rust inhibitors applied. Trade terms offered include FOB Tianjin and CIF ports, with minimum order quantities starting at 10 units. Buyers should confirm the exact disc material composition for compatibility with their fluid media.

Yuanda Valve Group Co., Ltd. is based in Longyao County, Hebei Province, China, and operates as a manufacturer of industrial valves with harbor-level trust verification.
