Production & Quality Assurance
Manufacturing steps
• Copper coil winding with automated tension control ensures consistent electromagnetic force.
• ABS body injection molding with metal thread inserts provides mechanical strength and corrosion resistance.
• Diaphragm and plunger assembly under controlled clean environment, followed by ultrasonic welding of valve housing.
• Terminal crimping and wire harness connection are 100% inspected for pull‑off strength.
In‑line and final tests (each valve)
• Coil resistance and insulation resistance measurement.
• Air‑under‑water leakage test across full pressure range (0.02–1.0 Mpa).
• Flow rate verification at rated pressure.
• Functional cycling test (sample batch) to confirm response consistency.
Based on internal after‑sales tracking across exported lots, the annual field return rate for these water inlet valves remains below 0.2% under intended operating conditions, reflecting the effectiveness of the described quality system.
Design Features
• Available in single‑inlet (cold only) and dual‑inlet (hot/cold) versions to suit different washer designs.
• Copper coil ensures stable operation under continuous duty and resists thermal degradation.
• Wide voltage tolerance (AC100–240V) accommodates grid fluctuations in various regions.
• Sealing system maintains zero visible leakage within the rated pressure window during production testing.
• Compact body with standard 3/4″ thread simplifies direct replacement of most original equipment valves.
• Low power draw (≤5 W) reduces energy consumption and heat build‑up.
• Operating noise ≤35 dB, suitable for domestic laundry environments.
Installation & Maintenance
Installation steps
1. Disconnect the washer from mains power and close the water supply taps.
2. Remove the old valve, clean any sediment from the inlet hose filter and pipe threads.
3. Hand‑tighten the new valve then apply 3–5 N·m torque; connect the outlet hose securely.
4. Attach the wiring harness (confirm voltage marking) and restore water supply to check for leaks.
Preventive maintenance
• Inspect and clean the inlet filter screen every six months, especially in hard‑water areas.
• Ensure water pressure does not exceed 1.0 Mpa; install a pressure reducing valve if necessary.
• If the washer will be idle for extended periods, close the water taps and run a short empty cycle to drain residual water.
Packaging & Delivery
Each valve is packed in a 5‑layer export‑grade corrugated carton, with 60 units per carton. Custom packaging (blister card, color box with printing) is supported for OEM orders. Small trial quantities are shipped via DHL, FedEx or EMS (typical 5–7 business days), while bulk orders are delivered by sea or air freight with full tracking and customs documentation.

Common Questions About Washing Machine Inlet Valves
Q: How do I know whether my washing machine needs a single or dual inlet valve?
A: Check the existing valve or the washer’s user manual. If only a cold‑water hose is connected, a single inlet valve is sufficient. Machines with both hot and cold supply hoses require a dual inlet valve. You can also inspect the number of solenoid coils visible on the valve body.
Q: Can I replace a dual inlet valve with this single inlet version?
A: Only if your washing machine is designed to operate with cold water alone and the hot water inlet is permanently capped. However, most dual‑inlet machines rely on temperature selection and need both channels to function properly. We recommend matching the original configuration.
Q: What should I check before ordering a replacement water inlet valve?
A: Verify the voltage (usually marked on the coil), thread size (most common 3/4″), number of inlets (single or dual), and physical mounting dimensions. Sending a photo of your original valve to our sales team can speed up confirmation.
Q: The valve hums but no water enters. What could be the cause?
A: A humming sound usually means the coil is energized but the plunger cannot move freely. Common causes include a clogged inlet filter, debris stuck under the diaphragm, or water pressure below the minimum 0.02 Mpa. Clean the filter and retest; if the problem persists, the valve may need replacement.
Q: Can this valve be used with hard water?
A: Yes, but hard water may accelerate scale build‑up on the filter and internal passages. Regular cleaning of the inlet filter (every 3–6 months) is recommended to maintain flow rate and response time. The valve body and sealing materials are selected to resist typical mineral deposits.
Q: Do you provide installation instructions with the valve?
A: A printed installation guide is included in each shipment. Additional technical resources can be provided upon request.
Q: Are custom voltage or connector variants available?
A: Yes. We support OEM customization including DC voltage options, different terminal styles, and wire harness lengths. Please provide your target specifications for evaluation.
