HOWO CNG engine parts overflow valve WG9000360519,special used for Sinotruk CNG truck parts
FUNCTION
1. Automatic Overpressure Relief Protection: When the air pressure within the pneumatic braking system (specifically at the air compressor, air reservoir, or downstream of the air dryer) exceeds a preset threshold, the valve spool automatically opens to vent excess compressed air into the atmosphere. This prevents system overpressure, thereby averting potential hazards such as: the bursting or deformation of air reservoirs; the rupture or leakage of air lines, fittings, or brake valves; and damage to the air dryer or other pneumatic components.
2. System Pressure Stabilization: The valve remains closed during normal operation, ensuring that system pressure is maintained within a safe operating range and preventing pressure fluctuations that could compromise braking performance.
3. System Overload Prevention: In instances where the air compressor continues to supply air, the relief valve serves as the "last line of defense," providing timely pressure relief to safeguard the entire pneumatic circuit system against damage caused by extreme high-pressure conditions.
Advantages
1. Precise Pressure Control and Rapid Response: The set pressure is precisely 0.6MPa, with stable opening/closing thresholds and millisecond-level response time. It immediately releases pressure when the system pressure slightly exceeds 0.6MPa to prevent overpressure accumulation; the seal quickly resets as the pressure drops, reducing frequent pressure releases or fluctuations.
2. Excellent Sealing Performance, Zero Leakage: A multi-seal structure of valve core + spring + O-ring ensures reliable sealing in the closed state, with virtually zero leakage.This prevents frequent leaks from causing insufficient or overpressure-induced pipe rupture.
3. Outstanding Safety Protection Capabilities: As the "last line of defense" in the air circuit, it promptly unloads the air compressor's unloading valve when it fails or when the air supply is idle for extended periods, preventing the air tank from bursting, pipes from rupturing, or the brake valve from being damaged.

Regular inspection: Every 10,000-20,000 kilometers or every major maintenance, check the valve body for leaks (by touching or listening), whether the pressure relief is normal (there should be an exhaust sound when the pressure gauge exceeds 0.6MPa), and whether there are foreign objects/rust on the valve port.
