How Does It Work?
With the coil de-energised the valve is closed. When the coil is energised, the core is pulled up, the pilot orifice opens and the pressure difference lifts the diaphragm to let the medium flow. When power is removed, the valve closes.
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.
