Sz914000723
Shacman
| Attribute | Specification |
|---|---|
| Voltage | 24V DC (Standard for heavy-duty trucks) |
| Control Method | Electric actuator (on/off or PWM signal depending on vehicle configuration) |
| Function | Electronically controls the flow of engine coolant to the cabin heater core |
| Material | Metal (Iron or Aluminum alloy) body with heat-resistant plastic components and seals |
| Interface Type | Standard rubber hose barb connections for truck cooling systems |
| Hose Inner Diameter (Typical) | Approx. 16mm / 5/8" (Confirm with vehicle manual or physical measurement) |
| Operating Pressure | Compatible with standard engine cooling system pressure (typically 0.9–1.5 bar) |
| Temperature Range | -40°C to +120°C (withstands hot coolant and cold start conditions) |
| Sealing Type | Rubber O-rings or gaskets (resistant to ethylene glycol-based coolants) |
| Mounting Style | In-line installation in heater hose circuit; secured with clamps |
| Origin | Manufactured in Shaanxi or Shandong, China |
| Warranty | Typically 3 to 12 months (varies by supplier) |

Name2
Compatibility Verification Required
Confirm fitment using:
Some vehicles may have different HVAC configurations even within the same model line.
Exact truck model and series
Year of manufacture
VIN (Vehicle Identification Number)
Existing valve connector type and hose orientation
Professional Installation Recommended
Due to involvement with the engine cooling system, installation should be performed by qualified technicians.
Coolant Handling Procedure
Drain coolant properly before removal.
Refill with correct type of antifreeze (usually ethylene glycol-based, low-silicate, long-life formula).
Bleed air from the cooling system after installation to prevent overheating or poor heater performance.
Check Electrical Connection
Ensure the 24V power supply and control signal are stable.
Inspect wiring harness and plug for damage or corrosion.
Test valve operation (listen for click or use multimeter) before full reassembly.
Leak Inspection After Installation
Check all hose connections and clamps for tightness.
Run engine at operating temperature and inspect for leaks.
Avoid Mixing with Manual Valves
Do not replace this electric valve with a manual or mechanical version unless the entire control system is modified — doing so will disable automatic climate functions.
Storage Conditions (If Not Installed Immediately)
Store in dry, room-temperature environment.
Keep ports sealed to prevent contamination.
