Import Delivery Valves — Buy in Bulk from Supplier in China

The delivery valves offered by China-lutong Parts Company are generic components designed for use in diesel fuel systems, typically serving as replacements for worn OEM parts in medium-duty engines. These valves are machined from carbon steel and feature a conical seating surface with a nominal diameter range of 6.0 to 7.0 mm, depending on the pump variant. The valve stem is ground to a surface finish of Ra ≤0.8 μm and operates under pressures up to 1500 bar.

The materials used are standard industrial-grade carbon steel without specified alloying elements or heat treatment details. Surface coatings, if applied, are not declared but are commonly zinc plating or basic phosphate treatments in similar aftermarket products. Typical tolerances for stem diameter fall within ±0.01 mm, which is broader than OEM specifications. These valves are not certified to ISO 11224 and are intended for non-critical applications where cost is prioritized over precision.

Primary buyers include small-scale diesel repair shops, agricultural equipment service centers, and regional distributors in emerging markets. Valves are supplied in bulk packs of 25 or 50 units, packaged in polyethylene bags with cardboard inserts. Trade terms are typically FOB Putian Port. Buyers should confirm lead time and minimum order quantity directly with the supplier, as neither is disclosed in the listing.
