Import Boch Zexel Denso Delivery Valve Mw D/Valve — Buy in Bulk from Supplier in China

The Boch Zexel Denso Delivery Valve Mw D/valve is a precision diesel injection component designed for fuel delivery control in heavy-duty diesel engines, including applications for Volvo BMD 60 A, Volvo TD 60 B, Mercedes-Benz OM 364.981 LA, Mercedes-Benz OM 366 LA, Mercedes-Benz OM 364.954 A, Liebherr 914, MAN D 0826 LE, Fendt D 0286 LE 523, and Renault MIDR 06.02.26 X. The valve body carries stamped identification numbers 201112, 202112, 203112, 207112, 208112, 215112, 221112, 227112, 228112, 233112, 234112, and 238112, cross-referenced to Bosch numbers 1418 512 series. These valves regulate fuel pressure and timing by controlling the precise opening and closing of the injection nozzle circuit, a critical function for engine efficiency and emissions compliance in European commercial vehicle and industrial engine platforms.

Manufactured from hardened alloy steel with precision-ground sealing surfaces, delivery valves of this type typically incorporate a valve seat, plunger guide, and pressure-relief geometry matched to specific pump configurations. The coking resistance and wear properties of the material determine service interval, with OEM-grade units generally specified for 500,000 km or 15,000 operating hours in heavy truck applications. Tolerances on the sealing diameter and guide clearance are typically held within micrometre ranges to prevent fuel leakage and ensure repeatability across the full temperature and pressure envelope of common rail and inline pump systems. The part numbering system follows Bosch conventions, with the 1418 512 prefix denoting a specific delivery valve family for medium and heavy commercial vehicle engines.

Importers targeting European aftermarket or engine rebuild sectors use these valves in pump remanufacturing, fleet maintenance, and authorised service operations. Sourcing from Fujian-based Diesel Injection Parts Plants requires verification of material certification, dimensional inspection reports, and cross-reference confirmation against the target engine serial number, given the close tolerance between compatible and incompatible variants. The supplier lists no response data, so direct enquiry on current stock, minimum order quantities, and export documentation is essential before committing to purchase.

Diesel Injection Parts Plants operates from Longqiao Street in Putian, Fujian Province, China, a region with established machining and component manufacturing infrastructure. The supplier holds a Harbor trust tier classification, which indicates a baseline marketplace presence rather than verified or audited status. The response rate is recorded at 0.00% with zero average response hours, signalling that direct communication channels may be unmonitored or that the profile has limited active engagement. No independent certification, factory audit results, or trade assurance details are present in the available profile data.

The listing specialises in diesel injection components with explicit cross-reference data for European engine manufacturers, suggesting either direct manufacturing capability or sourcing relationships with tier-two component producers. The address places the operation within Putian's industrial zone, though the profile provides no information on production capacity, quality management systems, in-house testing equipment, or export documentation services. Buyers should request ISO 9001 or IATF 16949 certification status, material test certificates, and dimensional inspection reports before placing orders. The lack of response metrics means that initial contact, sample availability, and negotiation of trade terms will require persistent follow-up through alternative channels.
