Solenoid valve

Meaning in robotics & automation, with examples

/ˈsoʊlənɔɪd vælv/nounCommon term

In robotics & automation, solenoid valve means: A valve that is opened or switched by an electric coil to control the flow of air or liquid. In pneumatics it sends air to one side of a cylinder or the other.

In Turkish: selenoid valf, solenoid valf, elektrovalf, bobinli valf

How it is used

Valves are described by ports and positions: a 5/2 valve has five ports and two positions and may have spring return or two coils. Valves are often mounted on a valve terminal (valve island). Common faults are a burnt coil or a stuck spool.

Example sentences

  1. The solenoid valve gets the signal, but the cylinder doesn't move; the coil may be burnt.

  2. We use a 5/2 solenoid valve with spring return for the clamp.

Common collocations

  • 5/2 valve
  • valve coil
  • valve terminal
  • energize the solenoid
  • manual override
  • pneumatic cylinderAn actuator in which compressed air pushes a piston to produce straight-line movement, used for clamping, pushing, lifting and many other simple motions in machines.
  • actuatorA component that turns energy, such as electricity, compressed air or hydraulic oil, into movement. Motors and pneumatic or hydraulic cylinders are typical actuators.
  • I/OShort for inputs and outputs: the signals a controller receives from sensors and buttons, and the signals it sends to valves, motors, lamps and other devices.
  • relayAn electrically operated switch: a small current through its coil opens or closes contacts that switch another, often larger or separate, circuit.
