solenoid valve working principle?

Solenoid valve working principle
  • Under normal conditions, the air from hole 1 continues to hole 3, the air from hole 4 continues to hole 2, while hole 5 is blocked, referring to the figure below.
  • when supplying electricity to the solenoid Will cause a mechanism to push the valve spool to the right hand side. The air from hole 4 will continue to hole 1, while the air from hole 2 will flow to hole 5, while the hole is 3 tons.
  • when the electricity is cut off from the solenoid The spring will push the ball back to its normal position.

How many types of solenoid valves are there?

Solenoid valve 5/2

Types of solenoid valves will be divided by numbers, as follows: 2/2, 3/2, 4/2, 5/2, and 5/3. Based on the above example, Solenoid valve 5/2 used mainly in pneumatic systemsP

  • The first number is the number of inlets and outlets of the valve. It indicates that the valve. How many entrances or exits are there (ports)?
  • The second number is the number of positions or positions that the valve can change.
