Solenoid Fuel Valve – Normally Open

What is Solenoid Fuel Valve?

Solenoid Fuel Valves; They are electromagnetic valves that allow to control fluids such as natural gas, air, petroleum derivatives, water. Thanks to the electrical power supplied to the coil, the piston in the valve moves. The electric current moves in the coil, the piston becomes an electromagnet and the piston moves according to the usage situation of the coil. In this way, the inlet channel pushes the fluid in the direction of the outlet. If the signal is interrupted, the valve returns to its original state and the flow of fluid is prevented.

How Does the Solenoid Fuel Valve Work?

The solenoid fuel valve works by using an electromechanical device called a solenoid to control the flow of fuel to a vehicle’s engine. A solenoid is a coil of wire surrounded by a magnetic field when an electric current flows through it. When electric current is applied to the solenoid, it creates a magnetic field that attracts the moving core inside the solenoid. The movable core is connected to a valve that controls the fuel flow.

When the solenoid is activated and the moving core is pulled into the center of the solenoid, it opens the valve and allows fuel to flow from the fuel tank to the engine. When the electric current to the solenoid is turned off, the magnetic field disappears and the moving core returns to its original position, closing the valve and stopping the fuel flow.

The solenoid fuel valve is controlled by the engine’s electronic control module (ECM), which sends an electrical signal to the solenoid to open or close the valve as needed. The ECM monitors various sensors in the engine such as throttle position, engine speed and airflow and adjusts the solenoid fuel valve accordingly to maintain the proper fuel-air ratio for efficient combustion and prevent engine damage due to overloading. .

Normally Open State Operating System

Normally Open Solenoid valve initially allows the passage of fluid. In order to close the valve, the coil moves with the electric current coming to the coil, pushing the core down and closing the mouth of the orifice hole, and in this case, the pressure inside increases gradually and pushes the diaphragm down and closes the orifice through which the fluid passes. In a short time, the pressure spreads homogeneously on the diaphragm and the pressure higher than the pressure of the fluid prevents the fluid from lifting the diaphragm, so the valve is in the closed position. All this happens in a very short time. Our product is designed to get the best efficiency.

Suggestions

Mount the solenoid valve so that the coil is up. In the installation, such as a strainer before the solenoid valve, etc. use filters. We use more durable diaphragm and gasket material for high temperatures
Please specify your diaphragm and gasket request for high temperature in your orders.

Things to Consider When Choosing a Solenoid Valve:

• The coil should be selected in accordance with the operating voltage (AC-DC). Protection and insulation should be provided according to the place where it will be applied. (Electricity turns on when air comes in, and turns off again when you cut off the electricity)
• In the line or system you will use, min. and max. pressure values are very important in the selection of the valve.
• The quality and temperature of the fluid is a direct factor in the selection of the valve.
• The direction of the fluid and the arrow mark on the body are in the same direction and attention should be paid to the assembly.
• Since the solenoid valve does not function as a check valve, the fluid flows back at reverse pressures. In these cases, installing a check valve after the solenoid valve is correct for the connection.
• The line to which the valve is attached must be free of impurities.
