How Does It Work?
A 3/2-way valve has three ports. De-energised, the inlet is closed and the outlet is open to exhaust; energised, the inlet is connected to the outlet. It is used to control pneumatic cylinders and actuators.
Applications
- Water and irrigation lines
- Compressed air
- Neutral gases
- Light oils and liquids
- Machinery and automation
Selection and Installation
Install the solenoid valve with the coil on top and fit a strainer upstream. For high temperatures, specify the diaphragm and seal material when ordering. Specify the coil voltage (AC/DC) when ordering.
