Electric Valve for CNG Tank Emer VBE 474 - Electromagnetic Valve with M12x1 Connection - 12V Solenoid Valve for Natural Gas Installations - Bi-directional Valve for Compressed Natural Gas Systems
Professional Electromagnetic Valve for CNG Systems
This high-quality electric valve from the Italian brand Emer is specially designed for CNG tanks in vehicles running on natural gas or compressed natural gas. The electromagnetic valve type VBE 474 forms an essential component of the CNG installation and regulates the gas supply from the high-pressure gas tank to the engine. This solenoid valve operates on 12V direct current with a power of 12.8 Watts and is designed according to the highest safety standards for use in autogas systems. The valve functions as a normally closed valve that opens when current is applied, releasing the gas supply to the engine.
Technical Specifications and Features
The Emer VBE 474 valve features two identical M12x1 threaded connections, both of which can serve as either inlet or outlet. This bi-directional configuration makes installation flexible and simple, as the valve has no fixed flow direction. The valve can withstand working pressures up to 200 bar, which is typical for CNG applications in passenger cars, vans, and even heavy vehicles. The valve is manufactured from high-quality materials such as brass and stainless steel, which resist the high pressures and temperature fluctuations in natural gas systems. The magnetic coil is equipped with a Bosch connector with polarity marking and can be easily replaced without dismantling the entire valve, simplifying maintenance.
Compatibility and Applications
This CNG valve is compatible with various brands of natural gas conversion systems, including installations from BRC, Tartarini, Landi Renzo, and other manufacturers using Emer components. The valve is used in combination with CNG pressure regulators, vaporizers, and injection systems to run vehicles on methane or natural gas. The valve is mounted directly on the CNG tank or in the high-pressure gas line and regulates the gas supply from the tank to the vaporizer or pressure regulator. This type of valve is suitable for both light vehicles such as passenger cars and commercial vehicles and forms a safety component that automatically shuts off the gas supply when the engine is turned off.
Installation and Maintenance
When installing the electric valve, you must ensure proper sealing of the M12x1 threaded connections by using suitable sealing rings or sealing paste resistant to natural gas. The valve can be mounted in any position, as long as the magnetic coil remains well-ventilated and is not exposed to extremely high temperatures. The electrical connection must be made according to the polarity marking on the connector and connected to the vehicle's 12V onboard network via the engine management system or CNG ECU. Regular inspection of operation is recommended, watching for strange noises, slow switching, or gas leaks. The magnetic coil can be easily replaced if necessary without removing the valve from the gas line. Annual inspection of all CNG components, including this valve, is mandatory according to current regulations for natural gas vehicles.
