Original Standard Solenoid Valve Assembly for CAT C18 Excavator Engine with Precise On-Off Control and High-Pressure Resistant Forged Brass

For 281-8687 2818687  Solenoid Valve Assembly CAT C18 Excavator Engine Parts

Specification

Description

281-8687 solenoid valve assembly is an original standard hydraulic control solenoid component specially developed for C18 series excavator diesel engines. It integrates an electromagnetic coil, brass valve body, sealed valve core assembly and special wiring harness connector. As a core actuator of the engine electronic control system, it realizes precise on-off control of engine fuel system, exhaust gas control and hydraulic oil circuit. The product fully complies with original dimensions, interface specifications and electrical parameters. The valve body is made of high-pressure resistant forged brass, which adapts to harsh construction machinery conditions including high temperature, vibration and oil pollution. It supports direct plug-and-play original position installation, and perfectly matches original oil circuits and electrical interfaces.

Advantage

Precise Original Matching: Fully compliant with original design parameters, installation dimensions and electrical interfaces. 1:1 original position replacement, no modification or debugging required, stable operation immediately after installation.
High-Durability Valve Material: Integral forged brass valve body, with excellent corrosion resistance, high pressure resistance and hydraulic impact resistance. It is resistant to leakage, deformation and cracking in long-term use.
Stable Electromagnetic Performance: High-precision electromagnetic coil with fast response, sensitive opening & closing, low power consumption. It maintains stable magnetic force without overheating or attenuation during long-time continuous operation.
Integrated Assembly Design: Factory pre-assembled integrated unit of valve body, coil and wiring connector. Integrated sealed structure with high dust-proof, oil-proof and waterproof grade.
Harsh Working Condition Adaptation: Adaptable to outdoor harsh operating conditions of excavator engines, including continuous vibration, high temperature, heavy oil pollution and wide voltage fluctuation, with extended service life.

Performance

Electrical Parameters: 24-32V DC wide voltage adaptation, 34.9W rated power, fully meeting construction machinery vehicle power supply standards.
Pressure Resistance Performance: 150PSI rated oil circuit pressure, resistant to instantaneous hydraulic impact, with zero leakage oil circuit sealing.
Response Performance: Millisecond-level fast opening & closing after power-on. The valve core moves accurately without delay or jamming, with high control precision.
Environmental Adaptability: Working temperature range -20℃~125℃, resistant to high temperature aging in engine compartment, engine oil corrosion and continuous vibration.
Installation Performance: Standard threaded oil port + special waterproof electrical connector, plug-and-play design, easy assembly & disassembly, with high sealing reliability.
Application Scope: Specially used for on-off control of oil circuits in fuel control system, exhaust gas recirculation system and auxiliary hydraulic control system of C18 excavator engines.
