Solenoid valves are commonly used in central heating systems to control the thermostat to regulate the flow of heated water to the heating element. They are used in machinery, devices, and equipment such as refrigerators and automatic faucets. Solenoid valves are used in a wide variety of industries. More information can be found at Engineering360's How to Select Linear Solenoids and How to Select Rotary Solenoids pages. This type of valve is also called a servo-type valve. The inlet pressure opens and closes the valve seal. Pilot-operated: Solenoid valves can also be considered pilot-operated, which means the plunger opens and closes a pilot orifice.

De-energized state: Normal close, normal open or DivertĦ.Direct-acting: Solenoid valves can be considered direct-acting, which means that the plunger directly opens and closes the orifice inside the valve.

This mechanism is used by solenoid valves to open or close the valve.ĭuring the choose of the Solenoid Armature, you should pay attention to below factors:ģ. This electromagnetic field causes the plunger to move up or down. When the electric current is passed through the coil, an electromagnetic field is created. If the solenoid valve fails to open or close, is partially open, makes a humming noise or has a burned-out coil, you need to troubleshoot the valve solenoids.Ī solenoid is an electric coil that is wrapped around a ferromagnetic substance (such as iron) that acts as an electromagnet when the current is passed through it.

How can you tell if your solenoid is bad? *According to valve application: Our armatures are widely used in pneumatic, hydraulic, fluid control fields, covering textiles, home appliances, automobiles, refrigeration and other automation control industries. *According to tube material: Brass, Stainless Steel Solenoid Valve Plunger Assembly Categories:
