Everything You Need to Know About an Air Solenoid Valve

The biggest industry in the world, when it comes to dollar value, is the oil and gas industry. It is a global powerhouse that employees hundreds of workers from all around the globe; simultaneously it generates enormous amounts in billions of dollars each year.

Oil and gas companies are vital, and they contribute towards a significant amount of the national GDP, and this fantastic success rate can’t be achieved without exploring, extracting, refining, transporting and marketing the end products; and the culmination of this process is essential to many industries. It is important that specific measures be taken to preserve the operation of great value, starting from regular maintenance schedules, double routine checks and streamed down replacement of essential devices like the air solenoid valve.

Typical Applications of the Solenoid Valve:

  • It is used in fluid power pneumatic and hydraulic systems; it controls cylinders, fluid power motors, and larger industrial valves.
  • Solenoid valves are used in factories and plants where the compressed air is not available.
  • Within domestic washing machines and dishwashers, the solenoid valves are used to control water entry into the computer
  • The solenoid valve is essential in the medical industry, when equipment has to be precise and to the point. The inspection of solenoid productions for the pharmaceutical industry is rigorous and is held at a high standard; this is understandable since someone’s life is at stake.
  • The other solenoid valves that are used are at an advanced method, and they vary in pressure and flow depending on the input signal.

Basic Components:

The solenoid valve has two significant elements- the solenoid and the valve.

The solenoid is a tubular coil of wire:It acts as an electromagnet when a current pass through it, at the same time the valve acts as a control device. It directs the flow of the fluid by shutting and opening, or partially obstructing pathways.

Solenoid Valve

Valve Body: This central part of the solenoid valve is inclusive of ports, seats, and orifice that permit movement of liquids whenever the solenoid is energized or de-energized.

Solenoid Tube Assembly: This is stainless steel, sealed and closed at one end, a cylinder is a guide channel of the movable plunger which moves magnetically. This valve has the solenoid coil fitted on the outside of the enclosed tube.

Moveable plunger: An electromagnetically inductive coil that is made of movable stainless steel; it gets attracted by the solenoid magnetic field and slides inside the tube.

PlungerSpring: This is a return spring that grips the movable plunger in place when it is energized and returns it to its position when de-energized.

Seat Seal: It is used to close a central valve opening, and it is located on the movable plunger.

Electromagnet (Solenoid coil): The electromagnet that consists of copper windings (solenoid) along with, a magnetic yoke (armature), when energized, generates a magnetic flux which attracts the movable plunger.
