Import Cast Iron Lift Check Valve — Buy in Bulk from Supplier in China

The Cast Iron Lift Check Valve from Tonglu Wanhe Valves Co., Ltd is a swing-free, vertical-lift design that prevents backflow in pipelines by allowing fluid movement in one direction only. It has a pressure rating of PN16 and is manufactured from cast iron to suit applications requiring durability under moderate pressure and temperature. The valve’s face-to-face dimensions conform to DIN3202-F1, and flanges are drilled to standard hole patterns for compatibility with existing piping systems.

Cast iron provides good vibration damping and cost efficiency for non-corrosive fluid systems. The valve body is typically sand-cast and machined to meet dimensional tolerances for flange alignment. Internal components such as the disc and stem are made from carbon steel or bronze, though the listing does not specify exact materials. Standard coatings or internal linings are not mentioned, so buyers should confirm if the valve is suitable for water with high mineral content or abrasive slurries.

This valve is commonly used in municipal water supply, sewage treatment, and light industrial processes where backflow prevention is critical. Buyers include engineering firms managing water infrastructure and plant operators in chemical and food processing. Trade terms such as L/C and T/T are offered, but MOQ and lead time are not stated. Packaging is typically in cartons or wooden crates with internal protection; exact details must be requested directly.
