Installation Guide for Smart Water Valve Controllers?

I. General Installation Steps?

Preparation?

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

Prepare tools such as Teflon tape, wrenches, and pipe pliers.

Verify that the smart water valve model matches the pipe size and confirm all components (e.g., seals, connectors) are included.

Pipe Connection?

Wrap Teflon tape clockwise around the outlet threads (at least 15 turns) to enhance sealing.

Align the valve’s inlet with the pipe connection, hand-tighten initially, then secure with a strap wrench (avoid over-tightening to prevent stripping).

For the outlet side, attach hoses or branch pipes with Teflon tape and a gasket to prevent leaks.

Electrical Installation?

For electric valves, connect to 220V AC power (non-light-controlled circuit) using a dedicated socket with waterproofing.

Separate signal lines (e.g., RS485 communication) from power lines and ground the shield at one end to prevent interference.

Mounting & Commissioning?

Large-diameter valves (DN≥200) require additional support brackets to distribute pipe stress.

Power on the system, calibrate the valve’s full-open/full-closed position, and test remote control via the smartphone app and sensor response.

II. Installation Guidelines by Scenario?

Residential Applications?

Location?: Install in concealed areas (e.g., above suspended ceilings or under kitchen cabinets) without damaging tiles. Ensure ≥500mm of working space.

Special Handling?: Retrofit inlet pipes with PPR ball valves; use a laser level to align drilling positions, ensuring mechanical alignment (tolerance ≤3mm).

Agricultural Irrigation?

Pipeline Layout?: Design main pipes according to terrain slope; adjust drip tape spacing to crop needs (typically 30–50cm).

Head Assembly?: Install pumps and filters near the water source; add backflow preventers for fertilizer injectors.

Industrial Applications?

Standards?: For flange connections, tighten bolts in three stages diagonally (final torque deviation ≤25%); high-temperature pipes require expansion joints.

Safety?: Use explosion-proof actuators (Ex d IIC T6 rated) in hazardous zones; ensure valve grounding resistance ≤4Ω.

III. Common Issues & Troubleshooting?

Leakage?

Cause?: Damaged sealing surfaces or loose bolts.

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

Malfunctioning Operation?

Cause?: Rusted valve stem or debris obstruction.

Fix?: Lubricate the stem, clean sealing surfaces, and check power/signal connections.

Communication Failure?

Cause?: Incorrect RS485 wiring or electromagnetic interference.

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

IV. Key Considerations?

Leak Testing?: Gradually open the main valve after installation, checking for leaks before powering on.

Maintenance?: Clean agricultural filters seasonally; calibrate industrial valves semi-annually.

Emergency Handling?: Confirm valve default state (fail-open/fail-closed) during power loss to prevent system failure.

Note?: Refer to the product manual for specifics; complex installations should be performed by professionals.
