The Automatic drain valve of JK99-520201 Manufacturer——Xiamen Jiedeng adopts a pioneering built-in installation design, significantly enhancing its corrosion resistance and collision resistance, making it suitable for harsh working environments. Based on the precise pressure difference sensing principle, it achieves pure mechanical fully automatic drainage without the need for electrical control intervention, and can precisely remove oil and water from the air storage cylinder. The working pressure of the product ranges from 0.03 to 1.20 MPa, featuring both large flow rate and high precision. It integrates dual drainage functions to achieve maintenance-free operation and also has an air path sealingity detection function, comprehensively ensuring the safe and reliable operation of the braking system.
1.First-in-class built-in installation: Installed entirely within the air storage cylinder through
connecting threads, minimizing external exposed parts
2.High protection design: Effectively reduces environmental corrosion and external collision risks,
with more reliable protection provided by the Auto drain valve structure
3.Strong scene adaptability: Particularly suitable for low-floor buses and harsh working
environments such as those in industrial and mining sectors
4.Significant performance advantages: Compared to traditional external drainage valves, it offers
stronger environmental adaptability and resistance to damage
5.Life guarantee: The product's lifespan and long-term operational reliability have been enhanced
from the structural level
Precise differential pressure sensing driving mechanism: Achieving fully automatic drainage based on the principle of precise differential pressure sensing: When the system air pressure drops by more than 0.02 ± 0.005 MPa, the pressure inside the valve chamber is greater than the system pressure, and the valve core automatically moves upward to open the drainage; after pressure balance, it automatically resets and seals.
Pure mechanical intelligent operation mode: Auto Air Tank Drain Valve for Bus and Coach. The entire process does not require any electrical control intervention. It is fully achieved through mechanical structures for intelligent start and stop. No external power supply or control lines are needed. The drainage timing is precisely controllable.
Systemic protection value: It can promptly and completely remove the oil-water mixture in the air storage cylinder, fundamentally avoiding faults such as rusting of the air braking system pipelines and freezing in winter, providing a reliable guarantee for vehicle braking safety.
The working pressure range covers 0.03 - 1.20 MPa, suitable for various commercial vehicle pneumatic braking systems; the pressure difference control accuracy reaches ±0.005 MPa, with industry-leading sensitivity; the single drainage volume can reach 0.12 - 19.00 ml, and the stable air flow volume is controlled within 0.02 ± 0.003 L.
The Pneumatic automatic drain valve features both high flow capacity and high precision, which not only meets the drainage requirements of large-capacity air storage tanks but also avoids unnecessary pressure loss. Its overall performance is excellent.
The product integrates automatic + manual dual drainage function. It can operate automatically on a daily basis. Once every 10 days or so, it performs a pressurized manual drainage to keep the valve body clean, achieving a maintenance-free design without the need for disassembly.
The Automatic air tank drain valve is particularly noteworthy for its ability to perform a system sealing integrity test. The intermittent slight leakage at the bottom is a normal process of pressure balance. Continuous leakage can alert for potential leakage faults in the pipeline system, providing a clear diagnostic basis for the health status of the vehicle's air circuit system.
