Solenoid Valve-DN20
187 units available with a short lead time.
A 12V DC motorised solenoid valve with a DN20 (20 mm) bore, designed for controlling water flow in automated projects. The valve integrates a DC motor with a metal reduction gearbox, providing high torque and low noise operation. It withstands up to 1.0 MPa static pressure.
The valve has three control wires: connect the blue wire to positive to open, the red wire to positive to close, and the yellow wire to ground. If power is removed, the valve holds its current position and can also be operated manually.
Key Features
- Motorised Control – DC motor with metal reduction gearbox for reliable open/close operation
- Three-Wire Interface – Blue (open), red (close), yellow (ground)
- Holds Position – Maintains current state when powered off, with manual override
- Sealed Motor – Waterproof design for reliable operation
- Anti-EMI – Electromagnetic interference shielding
