General Purpose Solenoid Valve – Normally Open (GEM A)

What is a General Purpose Solenoid Valve?

General Purpose Solenoid valve is a mechanical device that moves with the effect of a magnetic field around a coil through which electric current is passed. It is generally used to control the flow of liquids or gases such as water, air, oil or gas. These valves; The pilot valve can be switched on and off by connecting to a control system such as a switch or control device. Solenoid valves are widely used due to their small size and easy controllability.

Solenoid valves are manufactured in two types as normally closed (to open the closed valve when the coil receives energy) and normally open (to close the open valve when it receives energy from the coil).

Where Are General Purpose Solenoid Valves Used?

General Purpose Solenoid valves are a type of electromagnetic instrument used to control the flow of liquids and gases such as water, air, oil or gas. They are generally used in different areas such as automotive, white goods, industrial machinery and systems. For example, they can be used in fertilization systems in automobile engines or in cooling systems in white goods such as refrigerators. They can also be used to control liquid and gas flow in industrial processes or plants.

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. 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.
