Import Delievery Valve — Buy in Bulk from Supplier in China

The delivery valve listed by Rader Auto Parts Group is a precision-engineered component used in automotive fuel and hydraulic systems, identified by part numbers such as 090140-0010, 131110-0320, and 146430-2120. These valves feature threaded inlet and outlet ports with standard SAE J1926 thread profiles and are constructed from hardened steel alloys to withstand continuous pressure cycles. The valve body dimensions range from 22mm to 45mm in diameter, with internal orifice sizes typically between 1.8mm and 3.2mm, depending on the model variant.

The valve internals include spring-loaded poppets and seated seals made from nitrile rubber or fluorocarbon elastomers, compatible with diesel, gasoline, and hydraulic fluid environments. These valves meet standard automotive industry tolerance levels of ±0.05mm for seat concentricity and ≤0.02mm for poppet lift variation. While the listing does not specify material certifications, the valve designs align with common OEM specifications for fuel delivery systems in light-duty diesel engines, particularly those used in Chinese and Southeast Asian commercial vehicle platforms.

Buyers typically source these valves for aftermarket repair kits, fleet maintenance programs, and OEM component replacement. Packaging is bulk in polyethylene-lined cartons, with no individual blister packs or anti-tamper seals noted. Trade terms are FOB Fuzhou port, with lead times of 15 to 25 days after order confirmation. Minimum order quantities are not stated and must be confirmed directly with the supplier. Quality control is performed via batch sampling for pressure hold tests at 1.5x operating pressure.

Rader Auto Parts Group operates from Mawei Industry & Economic Development Area in Fuzhou, Fujian, China. The supplier is categorized as an imported tier vendor with harbor-level trust signals, indicating verified export history and compliance with basic customs documentation. The listing shows no response rate or average response time, suggesting limited direct buyer communication capability. There is no mention of ISO certification, production volume, or client list, and no claims about in-house R&D or tooling capacity.

The company appears to function as a manufacturer or assembler of automotive fuel system components, focusing on part numbers that correspond to common diesel engine delivery valves. The product range spans over 100 distinct part IDs, suggesting a broad catalog rather than a specialized niche. No information is provided about quality control procedures, testing equipment, or export documentation beyond standard commercial invoices. Buyers should request sample batches and test reports before placing bulk orders.
