Description
Product Overview
312-5620 Electromagnetic Drive Valve is the core driving component of the electronically controlled fuel injector. It controls the opening and closing of the internal valve core through electromagnetic force, precisely controlling the fuel injection timing and quantity. After long-term high-frequency operation, the electromagnetic coil is prone to aging and the valve core may get stuck, resulting in abnormal fuel supply. This complete drive assembly can be replaced separately for damaged components without needing to replace the entire fuel injector, significantly reducing equipment maintenance costs. It is suitable for the maintenance and repair of various heavy-duty diesel machinery fuel injection systems.
Unique Core Features of the Individual Product
Yellow high-temperature resistant electromagnetic housing, providing heat insulation protection for the internal coil
The lower part adopts a special yellow high-temperature resistant engineering plastic housing, isolating the high temperature transmitted from the engine cylinder, and the internal electromagnetic coil is less likely to be aged by heat, maintaining stable electromagnetic suction force even under long-term high-load operation, avoiding valve core movement delay.
Multiple tooth external threaded installation sections, stable positioning and good sealing performance
The upper section has an integrated long-threaded metal installation head, with regular thread spacing, tightly engaging with the fuel injector body when screwed in, and combined with the matching rubber ring for double sealing, preventing high-pressure fuel from leaking through the threaded gap and eliminating the accumulation of oil and carbon on the outer wall of the fuel injector.
Side-side waterproof connection socket, stable signal transmission
The side has an integrated black plastic-sealed connection plug with a snap-locking structure, ensuring that the plug will not loosen or short-circuit under continuous vibration of the equipment, and the internal sealing structure of the plug can prevent oil and water vapor from invading, reducing circuit error faults.
Complementary independent oil-resistant O-ring, replacement can be done in one step
The product comes with a matching black sealing rubber ring that is resistant to diesel and high temperatures. During maintenance and replacement, there is no need to match the sealing parts separately. The entire set can be completed upon opening the box, simplifying the maintenance supply process.
Multiple-point tight metal flanges, preventing the shell from loosening or cracking
The flange surface is evenly distributed with positioning holes, and the shell assembly is tightly fitted, preventing the plastic shell and metal threaded section from separating under oil pressure impact and mechanical vibration, extending the overall service life.
Application Scenarios
Suitable for corresponding series of electronically controlled fuel injector assemblies, mainly used in large loaders, mining construction equipment, high-power generator sets, and heavy engineering vehicles. Suitable for local maintenance and replacement of fuel injectors in areas with continuous high-temperature and heavy-load conditions in the mining and construction sites.
