Solenoid Valve Coils

Solenoid valve coils are typically used in a variety of applications, including medical devices, automotive products, aviation systems, and irrigation systems. They are also used to create locking mechanisms for doors or other obstruction-free openings.

The solenoid coil is known for its durability, low maintenance, and effectiveness at performing the tasks that it was designed for. It can tolerate extreme temperatures such as -40℃ to +50℃, has a lifespan of up to 10 years, and needs no replacement of oil or other fluids.

Function of solenoid coil

The prime function and purpose of solenoid coil is to convert the electrical energy into mechanical energy to initiate linear motion. A valve plunger is placed inside the valve coil. When the coil receives electric current, the line of magnetic flux turns a plunger into an electromagnet. The flux forces the plunger to slide further into the coil which causes the opening of the solenoid valves.

What are solenoid valve coils

A solenoid coil is an electric device which is tightly wrapped to the core by a metal wire to create a magnetic field around. When the current is passed through the solenoid coil, it creates an electromagnetic field which regulates linear motion. Similarly, a solenoid valve coil is used for the conversion of electrical energy into linear motion. The wire which covers or wraps the solenoid valve coil is made of copper wire or aluminum. When the coil is given electrical current, the copper wire immediately catches it and creates an electromagnetic field which results in motion. The creation of electromagnetic fields is the result of the placement of a ferromagnetic core inside the valve coil.

Causes of failures of solenoid coils

While using the solenoid valve coils, one needs to be very cautious as there are many risk factors that can harm or damage the coil. The application of excessive or least number of voltages can fail a coil and it can burn as well. Electrical incidents or spikes may also cause damage to the coil. Once the coil is burned or damaged, it can only be replaced but not repaired. The factors which may cause a failure of the coil include an incorrect amount of current or voltage, rusting, corrosion, dirt stuck in the system, irregular pressure, power failure, missing equipment and many more.

Types of solenoid valve coils

No matter how many types of solenoid coils there are, they all are responsible for the purpose of creating an electromagnetic field. There are many types of solenoid coils to use for different purposes. They have different functions, materials, and designs but the same electrical principle of work.

These are the main types of the solenoid coil:

Tape Wrapped Solenoid Coil

Encapsulated or Molded Solenoid Coil

DC C - frame Solenoid Coil

AC Laminated Solenoid Coil

DC D - Frame Solenoid Coil

Rotary Solenoid Coil

Linear Solenoid Coil

The Tape Wrapped Solenoid Coil is designed as a spool like component which is wrapped around by a conducting wire which helps create a magnetic field. They are further coated by an insulated tape. The following coil is purposed to be used extreme heat, flames, and puncture. The tape provides toughness to the solenoid coil. They are used on gold fingers to protect against wave soldering. In high performance toroidal coils, it works as a ground barrier or phase insulation.
