Model: 8112DY-010-20
Brand: Sunlight
The Electric Water Valve 8112DY-010-20 is engineered to precisely regulate coolant flow in vehicle heating systems. Integrated into the engine’s water circulation loop, this valve modulates flow to the heater core, enabling consistent in-cabin temperature control. Equipped with a DC brush motor actuator and 90° stem travel, it ensures reliable, accurate actuation under varied operating conditions.
| Feature | Specification | Benefit |
|---|---|---|
| Input Voltage | 24 VDC nominal (18–32 VDC allowable) | Compatible with most commercial vehicle systems |
| Rated Load Torque | 0.4 N·m | Smooth, stable valve actuation under load |
| Rated Load Speed | Optional | Customizable to application needs |
| Rated Load Current | ≤ 0.1 A | Energy-efficient performance |
| Stall Torque | ≥ 1.1 N·m | Strong startup under load |
| Stall Current | ≤ 0.5 A | Safe electrical limits |
| Noise Level | < 45 dB @ 10 cm | Quiet operation in vehicle cabin environment |
| Operating Temperature | –40 ℃ to +85 ℃ | Suitable for extreme climates |
| Net Weight | 0.550 kg | Compact and lightweight |
| Rotation Range | 90° | Ideal for open-close or modulated control |
| Opening / Closing Torque | ≤ 0.2 N·m | Low friction, responsive actuation |
| Flow Rate (Fully Open) | > 1000 L/h | High throughput for demanding heating needs |
| Water Resistance | IP54 | Dust and splash resistant for engine bay environments |
| Service Life | ≥ 50,000 cycles | Durable and long-lasting |
| External Leakage | Zero leakage @ 0.4 MPa for 3 minutes | Excellent sealing performance |
