Solenoid Fuel Valve Normally Closed

Description

Solenoid Fuel Valve Normally Closed

Solenoid Fuel Valve Normally Closed; These are electromagnetic valves that allow to control fluids such as natural gas, air, petroleum derivatives, water. Thanks to the electric power supplied to the coil, the piston inside the valve is allowed to move. The electric current moves in the coil, the piston becomes an electromagnet and the piston moves according to the use 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 passage of the fluid is prevented.

How Does a Solenoid Fuel Valve Work?

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

When the solenoid is activated and the moving core is pulled to 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 switched off, the magnetic field disappears and the moving core returns to its original position, closing the valve and stopping the flow of fuel.

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 required. 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-to-air ratio for efficient combustion and to prevent engine damage due to overloading.

Normally Closed State Operation System

The Normally Closed Solenoid valve initially allows the fluid to pass through. With the electric current coming to the coil to open the valve, the coil is activated and pulls the core upwards and opens the mouth of the orifice hole, so that the fluid under high pressure moves quickly to the outlet through the bypass hole. With this progress, the pressure inside drops very quickly and a pressure difference occurs inside. Due to this difference, the diaphragm overcomes the spring force and lifts upwards and the fluid is allowed to pass, thus the valve becomes open. All this happens in a very short time. Our product is designed to get the best efficiency.

Recommendations

Mount the solenoid valve so that the coil remains above. Use filters such as dirt trap etc. before the solenoid valve in the installation. We use more durable diaphragm and gasket material for high temperatures
Please specify your diaphragm and gasket request for high temperature in your orders.

Considerations in Solenoid Valve Selection:

• The coil must be selected according to the operating voltage (AC-DC). Protection and insulation should be provided according to the place where it will be applied. (Electricity is turned on when the air comes on, and when you cut the electricity, it takes the closed position again)
• Min. and max. pressure values in the line or system you will use are very important in the selection of the valve.
• The nature and temperature of the fluid has a direct influence on the choice of valve
• The direction of the fluid and the arrow mark on the body should be in the same direction and attention should be paid to the installation.
• Since the solenoid valve does not function as a check valve, the fluid flows back at reverse pressures. In these cases, it is correct to install a check valve after the solenoid valve in terms of connection.
• The line to which the valve is attached must be cleaned of debris.
