Detailed Installation Steps for Smart Water Valve Controllers?

I. Basic Installation Procedure?

Preparatory Work?

Turn off the main water supply and drain residual pressure from the pipes.

Verify that the valve model matches the pipe size (e.g., DN20, DN25) and confirm all accessories (seals, flange bolts, etc.) are included.

Pipe Connection?

Threaded Connection?: Wrap Teflon tape (≥15 turns) on the pipe threads, align with the valve inlet, and tighten clockwise by hand before securing with a wrench (final tightening should not exceed ? turn).

Flange Connection?: Align flanges and tighten bolts diagonally in stages (final torque deviation ≤25%). High-temperature pipes require expansion joints.

Welded Connection?: Grind welding bevels flat; ensure proper insertion depth for socket welding.

Electrical Wiring?

Connect the electric valve to a 220V power supply (recommended as an independent circuit). Shielded signal lines (e.g., RS485) must be grounded at one end.

Configure the smart controller’s Wi-Fi module (e.g., Alarm.com or Qolsys) as per the manual.

Functional Testing?

Gradually open the water supply, check for leaks, then power on the system. Test remote control, flow adjustment, and leak detection functions.

II. Installation Guidelines by Scenario?

Residential Applications?

Install in concealed areas (e.g., above suspended ceilings or inside cabinets), leaving ≥500mm of working space.

Retrofit inlet pipes using PPR ball valves and laser-align holes (tolerance ≤3mm).

Agricultural Irrigation?

Lay main pipes according to slope; space drip tapes 30–50cm apart. Install filters and backflow preventers at the headworks.

Industrial Applications?

Use explosion-proof actuators (Ex d IIC T6 rated) and ensure valve grounding resistance ≤4Ω.

III. Troubleshooting Common Issues?

Valve Leakage?

Cause?: Damaged sealing surfaces or loose bolts.

Solution?: Replace seals/gaskets and evenly re-tighten bolts.

Communication Failure?

Cause?: Incorrect RS485 wiring or interference.

Solution?: Confirm A/B line polarity and ground the shield at one end.

IV. Key Considerations?

Perform a 1.5× working pressure seal test after installation, holding for 30 minutes with no pressure drop.

Clean filters regularly (quarterly for agriculture, semi-annually for industry) and validate valve travel.

Confirm the default valve state (fail-open/fail-closed) during power outages to prevent system failures.

Note?: For complex installations, consult the product manual or contact a professional.
