Product Description
A solenoid valve is a type of valve that is controlled by an electric current. Its coil wire (also known as an electromagnet) is energized to produce a magnetic field that moves a plunger. The plunger moves to open or close the valve, allowing liquid or gas to flow through the valve or shut it off.
- Swift opening and closing speeds provide a budget-friendly fluid control option for your equipment and systems.
- Starts opening at 0 bar pressure.
- Provides a rust-resistant solution for your projects.
- Ideal for controlling water, wastewater, oil, gas, flue, and various other mediums.
