Two-way two-way bistable self-holding pulse solenoid valve

Widely used in automatic control of agricultural automatic irrigation, landscaping automatic irrigation, drip irrigation and so on. It can also be used for other gas and liquid automatic control. The valve body material is reinforced nylon PA66 (Germany)

Working medium: water, liquid, gas

Fluid temperature: -5 to 80 ° C

Working type: DC pulse type

Body material: reinforced nylon PA66 (Germany)

Sealing material: NBR

Interface thread: G thread NPT thread

 Working voltage: DC2.5～6.5V IP67

Coil resistance: 25Ω

Minimum current: 190mA

Pulse width: ≥10ms

When the non-energized state is in a closed state (ie, an initial state), the self-weight of the pilot valve movable iron core and the spring seal the pilot valve port to be in a closed state.

 When a path needs to be formed: the coil gives a forward DC pulse signal, the excitation circuit forms a magnetic field and generates a magnetic force, the movable iron core is attracted by the electromagnetic force, and the magnetic force of the permanent magnet inside the coil is de-energized, and the electromagnetic valve is opened.

 To close the solenoid valve, turn the solenoid valve off by applying a DC reverse pulse signal to the coil.

When the disconnection is required, when the power supply is disconnected, the pilot valve port is closed, the spool diaphragm is closed by the downward pressure difference, and the main valve port is opened, and the solenoid valve is in an open state.
