What a Solenoid Valve Unit Typically Does (in TOTO Toilets/Washlets etc.)

A solenoid valve in a toilet or washlet setup controls the flow of water automatically, often electrically or electronically, in response to a sensor or a flush control. Key functions include:

  • Controlling flush cycles or refilling

  • Possibly part of auto‑flush, bidet spray, or washlet (heated seat, bidet spray) systems

  • Turning water on/off under electric control

What Parameters / Specs are Important

To understand or replace a solenoid valve unit like the “HH55007 / SHXA19”, these are the spec/details you need to check:

SpecWhy It MattersVoltage (AC or DC, volts)The coil inside the solenoid must match the supplied voltage (e.g. 12V DC, 24V, 110V, 220‑240V AC etc.)Power consumption / currentTo ensure safe wiring, avoid overloads, ensure compatible control boards.Flow rateHow much water the valve allows through when open (litres per minute, GPM etc.). If too low, flush or refill will be weak.Pressure rangeMinimum and maximum water pressure for correct operation (e.g. 0.05 MPa to 0.75 MPa etc.).Thread connections / inlet…
