Description
1/2 inch WRAS latching / bi-stable plastic water solenoid valve – RPE R Mini 5105BB
A WRAS-approved latching (bi-stable) water solenoid valve designed for ultra-low power potable water control. The RPE R Mini 5105BB operates using short DC power pulses to change state, remaining open or closed without continuous power, making it ideal for battery-powered, solar and energy-efficient water systems.
Valve function and operation

Product summary
The RPE R Mini 5105BB is a highly efficient WRAS-approved latching water solenoid valve that dramatically reduces power consumption by requiring only brief DC pulses to operate. Once actuated, the valve remains in position without power, making it an excellent choice for modern energy-efficient and autonomous water control systems.
