Built-in Air Tank Drain Valve

The Built-in air tank drain valve is an integrated drainage component installed on the vehicle's air tank. It can efficiently remove water and oil stains from the tank, maintaining the stable operation of the air path. This product is manufactured by Xiamen Jiedeng Machinery Co., Ltd. and is purely made in China, with stable quality.

What is the Built-in Type?

This product is installed closely to the tank body, with only 10mm of exposed nut thickness, which can effectively resist impact and from crushed stone roads; it fits closely with the tank, and is easier to break ice at low temperatures, preventing freezing and clogging.

The overall design is simple and integrated, with stronger sealing performance. It can replace the traditional external drain valve and is suitable for various commercial vehicles, offering better durability and practicality.

What are the differences between built-in and external drainage valves?

The body of the external drainage valve is clearly protruding. When driving on a road with a lot of gravel, it is prone to being directly knocked by flying stones, causing the valve body to deform or the seal to fail.

The integrated embedded structure can effectively avoid such risks. The built-in air tank drain valve is installed closely to the air tank, with only a small part of the structure exposed. This can significantly reduce damage caused by stone impacts.

At the same time, the built-in drainage is more thorough, the gas path sealing is stronger, and the appearance is also neater and integrated. In terms of durability, protection, and overall appearance, it has significant differences from the traditional external type.

Is the built-in drainage valve more likely to freeze with a low-temperature environment?

Freezing of the drainage valve in low-temperature environments is a common problem. Many people mistakenly believe that the built-in type is more prone to freezing, but this is not the case.

The built-in drainage valve is more closely integrated with the gas storage tank, allowing the heat from the tank to better transfer to the valve body. This means it can break the ice more effectively when freezing occurs.

As the core component of the air tank drain kit, it is structurally closer to the lowest point inside the tank, resulting in less water accumulation and lower freezing probability at the source.

The external valve body is suspended and dissipates heat quickly, making it easier to completely freeze. In contrast, the internal type has significantly better stability and anti-freezing performance under low-temperature conditions.

Applicable scenarios

1. When driving on roads with many stones and prone to bumps, to prevent valve body damage from impact.
2. To achieve a clean and integrated chassis design without highlighting components that may affect the appearance.
3. In long-term low-temperature and humid conditions, to reduce the probability of icing and blockage.
4. To reduce the risk of air leakage and replace the easily loosening traditional air tank drain cock.
5. To prioritize long-term stability and reduce frequent maintenance and replacement scenarios.

Application Vehicle

The built-in drain valve has no specific restrictions on vehicle models and is applicable in a wide range. It can be perfectly compatible with various commercial vehicles such as heavy trucks, light trucks, buses, buses, trailers, and engineering vehicles.

This drain valve can seamlessly integrate with the installation interface of the traditional external drainage valve. For any vehicle models that originally used external drainage valves, replacing with the built-in type does not require any structural modifications.

Moreover, it offers better protection, sealing performance, and overall aesthetics, and has extremely strong versatility.
