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 & outlet sizes and typesMust match existing plumbing / hoses / ports (e.g. ½‑inch, ¾‑inch, BSP/NPT, hose‑tail etc.).MaterialBody materials, seals, diaphragm type; resistance to calcium/scaling; durability etc.Mounting style & orientationHow it mounts inside the tank or housing; direction of flow; whether it needs certain clearance etc.Duty cycle / life expectancyHow many cycles it can reliably handle; sealing when closed; how fast it opens etc.Electrical connectors / control interfaceType of connector, wires, waterproofing etc.

What to Do to Identify HH55007 / SHXA19 Spec

Since direct spec was not found in public sources, here are steps you can do to find out exactly what you have:

1. Open the unit (if safe to do and if you have removed power/water) and inspect for markings. Sometimes the coil or the body will have voltage, model numbers, manufacturer markings.
2. 
   
3. Measure connections: Thread sizes, hose diameter, physical dimensions (length, height).
4. 
   
5. Check controller / board: If this solenoid is driven by a board or sensor, see what voltage it is supplying to the solenoid. That gives clue for coil spec.
6. 
   
7. Look up repair / service manual for your TOTO toilet / washlet model: These sometimes list the part number HH55007 and corresponding specs.
8. 
   
9. Contact TOTO service / spare‑parts dealer: Provide the code “HH55007 / SHXA19” plus any dimensions / photos; they may have internal documentation.
