What is a pneumatic solenoid valve used for?
Solenoid valves are electrically operated valves that operate under electromagnetic force. They operate when an electrical current passes through a solenoid coil, generating a magnetic field and opening the valve. So, what is a pneumatic solenoid valve used for and what is it? Continue reading our helpful guide to find out more information.
How does a solenoid valve work?
Inside a solenoid valve are two components: a solenoid and a valve body. The solenoid has a coil around an iron core at the centre, which is called a plunger. When the current passes through the solenoid, the coil creates a magnetic field, creating a magnetic attraction with the plunger, moving it and overcoming the spring force.
If the valve is normally closed, the plunger lifts to open the seal which allows the flow of liquid or gas through the valve. However, if the valve is normally open, the plunger moves downwards so the seal stops the flow.
The main purpose of a solenoid valve is to make processes more efficient. They’re at the heart of many modern applications because they can be programmed easily to switch processes on or off without much human input. Modern industry relies heavily on automation using a wide range of technological and computer-controlled systems, hence the use of solenoid valves. Also, because they can be installed easily and are easy to use. Solenoid valves can be positioned in remote and inaccessible locations and controlled electronically.
What is a solenoid valve used for?
- Refrigeration systems – Used to reverse the flow of refrigerants which helps in cooling during summer months, and heating during winter.
- Irrigation systems – The solenoid valve controls the flow of water in a sprinkler system by applying a voltage over the coil, opening the valve which allows the liquid to flow through.
- Dishwashers – The valve controls how much water is flowing through the system to complete the cleaning of the dishwasher’s contents.
- Air conditioners – Used to control the flow of compressed air in an air conditioning system.
- Medical and dental equipment – Solenoid valves are used to control the direction, pressure and flow of fluid within medical and dental equipment, such as dialysis machines, dosing equipment, and blood pressure monitoring devices.
- Water tanks – Water tanks need solenoid valves to control the direction, flow and pressure of water within the system.
Industrial cleaning equipment – Solenoid valves are used in industrial cleaning equipment like pressure washers and floor cleaners.
Advantages of pneumatic solenoid valves
There are many advantages to using pneumatic solenoid valves. They’re extremely popular within many modern systems due to their benefits, which are:
- Highly efficient as lower power consumption is required for use
- Provides improved safety
- Easy installation
- Flexible based on the application being used within
- Compatible with DC and AC voltage
- Reduced downtime due to fast response time
- Low maintenance
