Rain Bird TBOSPSOL 9V DC latching solenoid for irrigation valves

Rain Bird 9V solenoid for irrigation valves

The Rain Bird TBOSPSOL 9V DC latching solenoid is designed for battery-operated irrigation systems. It allows compatible Rain Bird irrigation valves to be controlled electrically without requiring a conventional mains-powered irrigation controller. Its bistable switching technology uses short electrical pulses to open and close the valve, eliminating the need for continuous holding current. This makes the solenoid particularly suitable for irrigation installations where energy efficiency and battery operation are important.

The Rain Bird TBOSPSOL can be used as a replacement part or to convert compatible irrigation valves from 24V AC operation to battery-powered control. The manufacturer part number K80920 identifies the original Rain Bird replacement component and helps ensure the correct product is selected.

9V DC latching technology for battery controllers

The Rain Bird TBOSPSOL uses bistable 9V DC latching technology. Unlike a conventional 24V AC solenoid, it does not require a continuous electrical supply to maintain the valve's operating position. Instead, a brief electrical pulse changes the switching state. This significantly reduces energy consumption and makes the solenoid suitable for battery-operated irrigation systems.

The solenoid is compatible with Rain Bird ESP-9V, ESP-BAT-BT, TBOS, TBOS-II, TBOS-BT and WPX battery-operated irrigation controllers. These controllers send the electrical signals required to open and close connected irrigation valves. The solenoid itself does not contain a timer or programmable control function.

Compatible with Rain Bird DV, PGA, PEB and other valves

The Rain Bird 9V latching solenoid fits numerous Rain Bird irrigation valve series, including DV, DVF, ASVF, PGA, PEB, PESB, EFB-CP, BPE and BPES. This makes it suitable for residential irrigation systems, larger landscaped areas and professional installations. The solenoid is designed for compatible irrigation valves with a maximum operating pressure of 10 bar.

Compatibility with Rain Bird HV valves depends on the valve version. HV valves manufactured on or after June 30, 2025 feature an updated bonnet designed to accept the TBOSPSOL solenoid. Older HV valves are not compatible. Always check the exact valve model and manufacturing date before ordering a replacement solenoid.

Easy installation and reliable valve operation

The Rain Bird TBOSPSOL replaces the existing solenoid on a compatible irrigation valve. It is supplied with two attached electrical wires, each approximately 60 cm long with a conductor cross-section of 0.75 mm². Before installation, turn off the water supply, release any remaining pressure and disconnect the irrigation controller from its power source.

Connect the solenoid wires according to the instructions supplied with the battery-operated controller. Suitable waterproof wire connectors are recommended for connections inside underground valve boxes. After installation, test the valve using the controller to confirm correct operation. The Rain Bird TBOSPSOL provides a practical solution for reliable, energy-efficient irrigation valve control.

Frequently asked questions

Which Rain Bird irrigation valves are compatible?

The TBOSPSOL fits Rain Bird DV, DVF, ASVF, PGA, PEB, PESB, EFB-CP, BPE and BPES valve series. Compatibility with HV valves depends on the manufacturing date and valve version.

Can I convert a 24V AC irrigation valve to 9V operation?

Yes, provided the valve is compatible with the TBOSPSOL. Replace the existing solenoid with the 9V DC latching solenoid and connect it to a suitable battery-operated controller.

Is the solenoid compatible with the Rain Bird ESP-9V?

Yes. The TBOSPSOL is designed for use with the Rain Bird ESP-9V battery-operated irrigation controller.

Does the solenoid work with ESP-BAT-BT controllers?

Yes. The Rain Bird TBOSPSOL is compatible with ESP-BAT-BT battery-operated controllers and can operate suitable Rain Bird irrigation valves.

What does latching solenoid mean?

A latching solenoid uses short electrical pulses to change the valve's switching state. No continuous holding current is required to maintain the selected state.

Can I connect the solenoid to a 24V AC controller?

No. The TBOSPSOL is designed for compatible 9V DC battery-operated controllers and must not be connected directly to a conventional 24V AC controller.

How long are the connection wires?

The solenoid includes two attached wires, each approximately 60 cm long, with a conductor cross-section of 0.75 mm².
