Claber Solenoid Valves: 9V Bistable and 24V for Underground Irrigation

Claber Solenoid Valves: The Heart of the Underground System

Claber solenoid valves are electromechanical devices designed to manage water flow in different areas of your garden. Connected to a programming unit, they automatically turn the water on and off with extreme reliability. Made of impact- and weather-resistant plastic, they are available in two standard voltages to adapt to any type of system: electric or battery-powered.

Quick Guide to Tension (Don't Get It Wrong!):

  • 24V AC (Alternating Current): For control units connected to the domestic electrical network (e.g. Claber Multipla, Aqua-Home).
  • 9V Bistable (Latching): For battery-powered control units installed in wells (e.g. Claber Multipla 9V, Rainjet Module).

Advanced Features: Flow Control and Manual Opening

Problem: Sometimes the water pressure is too high and the sprinklers "mist" (fog), wasting water. Other times, you need to turn on the water manually to test the system but don't want to turn on the controller.

Solution: Claber professional solenoid valves are equipped with:

  • Flow Regulator: A knob above the valve that allows you to mechanically reduce the amount of water flowing through, stabilizing the sprinklers.
  • Manual Opening: By rotating the solenoid or the dedicated lever, you can open the valve manually to check if the sprinklers are working, without touching the programming.

Built-in Filter and Cleaning

Sand is the number one enemy of solenoid valves (it can prevent complete closure, causing leaks). Claber valves feature an internal, inspectable filter, but for maximum safety, we always recommend installing a central filter upstream of the entire system to prevent debris from reaching the valve membrane.

The Replacement Solenoid

If the valve no longer opens electrically (but operates manually), it's often just the solenoid (the black coil with the wires) that's burned out. There's no need to unscrew the entire valve from the pipes! You can just unscrew the old solenoid and screw in the new one (Claber sells it as a spare part), saving time and effort.
