Fuel Tank Electric Change-over Valve Assembly WG9925550711 FOR SINOTRUK HOWO TRUCK
FUNCTION
1. Automated Dual Fuel Tank Switching
This assembly is the core control component of the dual fuel tank system. By receiving electrical signals from the cab switch, it automatically switches between the main and auxiliary fuel tanks without manual operation of the fuel lines.
2. Synchronized Fuel Supply and Return Management
This is the most important function of this component: simultaneously switching the fuel supply line and the fuel return line. This ensures that excess fuel from the engine flows accurately back to the currently used fuel tank, completely solving the problem of fuel overflow or imbalance between tanks.
3. Airtightness Guarantee and Anti-Air Locking
The internal valve core is machined with high precision to ensure a complete seal in the fuel line at the moment of switching, preventing air from entering the fuel system. This effectively avoids engine stalling or starting difficulties caused by air entering the fuel line.
4. Precise Electromagnetic Drive
The built-in 24V high-performance electromagnetic coil has an extremely fast response speed (typically completing the switch within 0.5 seconds), ensuring smooth power output and no switching delay during vehicle operation.
Technical Highlights
1. Corrosion-Resistant Valve Core: The internal structure undergoes special treatment to withstand long-term diesel fuel corrosion, preventing the valve core from sticking or jamming.
2. Chassis-Level Vibration Resistance: Designed for the bumpy conditions of heavy-duty truck chassis, the internal components are securely connected, preventing accidental switching or mechanical damage due to vibration.
3. Industrial-Grade Waterproofing: Equipped with a dedicated waterproof electrical socket to prevent rainwater and mud from corroding the circuitry, ensuring normal operation even in harsh environments.
Installation Location
Installed on the inside of the vehicle chassis longitudinal beams. This location utilizes the beam structure to protect the valve body from direct impacts from road debris and external forces.
Located in the central area between the main and auxiliary fuel tanks. This design aims to shorten the length of the fuel lines from the two tanks to the reversing valve, reducing suction resistance and ensuring smooth fuel supply.
Performance Advantages
1. Precise and Efficient Electronic Switching: Utilizing high-performance 24V electromagnetic drive technology, the switching command response is extremely fast, ensuring continuous and stable engine power output during operation.
2. Synchronized Supply and Return Fuel, Completely Solving the Oil Overflow Problem: The valve's internal structure achieves synchronous interlocking between the fuel supply and return circuits. When switching fuel tanks, the return fuel automatically flows back to the corresponding tank, effectively preventing oil overflow, leakage, and uneven fuel distribution caused by misaligned return fuel.
3. Superior Sealing Performance and Anti-Airlock: Employing imported sealing rings, it possesses extremely strong resistance to diesel corrosion and aging. The high-precision valve core, combined with an optimized flow channel design, ensures that the fuel circuit maintains a vacuum state throughout the switching process, preventing air from entering and causing engine stalling.
