This little valve takes one supply of water and sends it to the nozzle you choose. Use the buttons to look inside it and watch the motor swing the core between the outlets.
A bidet water diverter valve is the part that decides which nozzle the water goes to. Instead of a separate valve for rear wash, feminine wash and self-clean, one rotating core routes a single pressurised supply to the outlet that is needed.
It sits between the incoming water and the nozzles. Water arrives already under pressure from an upstream solenoid valve, and the diverter only chooses the path it takes.
From the outside it is a small plastic block. Opening it up shows the stepper motor, the drive shaft, the rotating core with its channel, the seal rings and the three outlets that share the same supply.
Two ideas matter most: a single channel in the core can only face one opening at a time, and a stepper motor moves in exact steps so it can stop precisely over each port. Everything else holds the water in and keeps the unselected outlets sealed.
An upstream solenoid valve opens and lets pressurised water into the diverter's inlet pipe. The diverter itself does not pump or boost the water; it only steers what arrives.
A command turns the stepper motor through the drive shaft. Because a stepper moves in small, counted steps, it can park the core at exactly the angle the chosen nozzle needs.
The channel cut through the core is a single passage. As the core rotates, that passage swings around the inside of the body until it meets the opening of one outlet and lines up with it.
With the channel aligned, water flows from the inlet through the core and out of the selected outlet to its nozzle. The other outlets stay blocked, so none of the water leaks into them.
To change mode, the motor simply turns the core to the next position, re-pointing the passage at a different outlet. The same rotation can also bring the self-clean port into line to rinse the nozzles.
It is a small valve that takes one pressurised water supply and sends it to one of several nozzles. Instead of a separate valve for each nozzle, a single rotating core chooses the outlet.
A stepper motor turns in small, exact steps, so the core can be parked precisely over a chosen outlet. That makes switching between the wash modes repeatable without any gears or a position sensor.
A channel cut through the core lines up with only one outlet at a time. As the motor turns the core, the channel swings from one outlet to the next, so the flow follows whichever port is connected.
It flushes water over the outside of the wash nozzles to rinse them. It is one more outlet on the same diverter, selected by turning the core just as the wash modes are.
Seal rings press against the core where it meets the body. They keep the pressurised water in the connected channel and stop it slipping into the outlets that are not selected.
The diverter does not create pressure; it only routes water that is already pressurised. An upstream solenoid valve switches the supply on, and the diverter then decides which nozzle receives it.
