This listing does not claim compatibility with any specific brand or toilet model.

• Specs from label & photos: Model printed on coil label: ZNF-A. Coil voltage: 12V DC. PulseWidth: 30ms. Working pressure: 0.5-8 bar. Assembly type: dual solenoid valve manifold (2 coils) on a white plastic body with 3 large male threaded ports plus additional small ports for internal hose routing. Wiring: red/black leads with plug connectors - match your connector/pinout and wire length. Primary OE/Part reference: ZNF-DC12V (confirm the same marking/spec on your original part). Use: smart toilet/bidet water control such as inlet/flush/nozzle spray including feminine wash (function depends on your unit's plumbing).
• Install/replace tips: turn off power and shut off the water supply, then relieve pressure. Photograph hose routing and wiring; match the 3 threaded ports and any small hose ports exactly to your original manifold orientation. Hand-start threads and avoid over-tightening plastic fittings. Replace worn washers/gaskets and clean any inlet filter/strainer if present. Verify port/thread size before reconnecting. After install, restore water slowly, check all joints for leaks, then test actuation from the controller/relay output. Confirm the correct install position by your service manual and by matching the original part. Use only within the label range (12V DC control, 0.5-8 bar pressure).
• Fitment (no brand/model claims): this item is sold by part/spec. Confirm fitment by your original part’s markings and a physical match of the manifold shape, 3 threaded port layout, small hose ports, mounting points, and connector style. Label on this unit shows: Model ZNF-A, Voltage 12V DC, PulseWidth 30ms, Pressure 0.5-8 bar. If you are searching by OE# ZNF-DC12V, verify your old valve shows the same spec/structure before purchase. Not universal - do not substitute different voltage, different port/thread standard, or different wiring/connector.
• Troubleshooting keywords (not a guaranteed fix): feminine wash/front wash no water, rear wash weak flow, intermittent spray, no fill/no flush, valve clicking/buzzing, leaking at threaded joints. Before replacing, check water pressure, kinked hoses, clogged filters/strainers, and verify stable 12VDC output from the control board/relay. Helpful add-ons (sold separately): sealing washer/gasket set, inlet filter screen, hose clamps, and replacement water tubing matched to your toilet/bidet.
