FUNCTION
1. Regulate Clutch Assist Air Pressure: As a pneumatic control valve in the clutch operating system, it receives control signals generated when the clutch pedal is depressed and precisely regulates the airflow into the clutch assist cylinder. This assists in clutch disengagement, significantly reducing pedal operating force and improving driving comfort and ease of operation.
2. Achieve Smooth Clutch Disengagement and Engagement: Controlling air pressure output enables gradual clutch disengagement and rapid engagement, preventing incomplete disengagement or engagement shock. This ensures smooth gear shifting, stable starts, and reduces wear on the transmission system.
3. Integrated Braking Linkage Protection: When the brake pedal is depressed, it can link or prioritize control of the clutch system, automatically or assistedly disengaging the clutch to prevent power interference with wheel braking. This enhances braking safety and prevents transmission shock or loss of control risks caused by "braking in gear."
4. Precise Air Distribution and Safe Adjustment: The valve body's internal precision structure automatically adjusts the output pressure according to the input air pressure, preventing excessively high or low air pressure.
Advantages
| No. | Performance Advantage Category | Specific Advantage Description |
|---|---|---|
| 1 | High Quality and Long Service Life | Features precision valve core, spring, and high-strength seals meeting OEM original factory quality standards; fatigue-resistant, corrosion-resistant, and aging-resistant; designed for long service life (commonly 100,000–200,000+ km), stable and reliable in harsh heavy-duty truck environments with high intensity, vibration, and dust, reducing early leakage or sticking failures. |
| 2 | Fast and Precise Assistance Response | Rapid air pressure regulation response (millisecond level), precisely controls output pressure to the power clutch cylinder, achieving smooth clutch disengagement/engagement; significantly reduces pedal effort (from heavy to light and effortless), resulting in smooth shifting without impact or shudder, improving driving comfort and operational efficiency. |
| 3 | Excellent Brake Linkage Protection | Integrated Clutch Brake function links or prioritizes clutch disengagement during brake application, preventing power interference with braking; avoids driveline shock or loss of control from "driving in gear while braking," enhancing emergency braking safety and overall vehicle stability. |
| 4 | Stable, Reliable, and No Electronic Failure Risk | Pure pneumatic/mechanical structure with no electronic components or sensors, resistant to high/low temperatures and vibration; low failure rate, easy to diagnose (e.g., air leakage, sticking); well-suited to demanding conditions in HOWO, A7, T7H models, maintaining consistent performance over the long term. |
| 5 | Excellent Installation Compatibility and Maintenance Convenience | Compact size (approx. 115×45×25 mm) and lightweight (about 0.14-0.15 kg), perfectly matches HW19710 and similar transmission air-assisted clutch systems; standard mounting holes/interfaces for easy replacement (quick air line connection); widely available parts with OEM-level precision, reducing risk of secondary failures. |

Routine Maintenance Recommendations
1. Air System Maintenance: Keep the entire air system dry and clean. Replace the air dryer filter annually or according to the manufacturer's recommended schedule (to prevent moisture/oil from entering the valve body and causing jamming).
2. Maintain Correct Driving Habits: Avoid prolonged periods of half-clutching. Quickly release the pedal when starting/shifting gears to reduce frequent valve movement and wear.
3. Emergency Check: If the air pressure is normal but the power steering is malfunctioning, the power steering cylinder air line can be temporarily disconnected, but this should only be done for short-term emergencies. Repair as soon as possible.
