Holding Tank Drain Valve

Xiamen Jiedeng holding tank drain valve offers a one-year warranty / 100,000 km dual quality guarantee (whichever comes first), and can quickly melt ice at -40℃. The product has IP68 protection, 96-hour salt spray performance, terminal pull force ≥ 100N, and the single-time drainage time during driving is only 1-2 seconds. A monthly terminal pull force inspection mechanism has been established to avoid wiring faults, and it can withstand high-pressure washing of the chassis; it is always in stock, with complete installation guidance and fault handling technical support available, and is suitable for various commercial vehicle air tank loading applications.

Product introduction

Xiamen Jiedeng tank bottom valve can effectively replace the traditional manual drainage structure. The traditional manual drainage relies on the driver's manual operation, which is prone to forgetting to drain and causing water accumulation inside the tank, which can lead to rusting of the tank body. In cold weather, the accumulated water freezes and directly threatens the safety of the braking system. Xiamen Jiedeng tank bottom valve supports manual drainage through buttons and can also be set for automatic drainage upon power-on and automatic drainage upon power-off, etc., to quickly drain the condensate water at the bottom of the gas storage cylinder, reducing the risks of freezing and rusting, and providing a more intelligent and convenient way to ensure driving safety. The product is suitable for installation on the main unit and after-sales modification.

Advantages

Application Area

This universal drain valve is suitable for use in gas storage tanks of commercial vehicles such as heavy trucks, light trucks, trailers, and buses. It covers scenarios where the valve is pre-installed by the manufacturer, retrofitted by repair shops, or upgraded in bulk by fleets.

Production and Quality Inspection Process

Component incoming inspection, valve body assembly, terminal crimping, low-temperature aging, salt spray, IP68 water immersion multi-step testing. Monthly destructive random inspections of terminal pull force are conducted; finished products undergo simulated low-temperature freeze-thaw and chassis high-pressure flushing tests. All tests must be passed before they can be stored.

Precautions

During vehicle operation, it is prohibited to keep the drainage valve open for a long time to prevent the braking air pressure from dropping; install the control with appropriate torque to avoid damage to the valve body; strictly follow the instructions for wiring and prohibit unauthorized disassembly and modification; unauthorized modifications are not covered by the warranty. For the northern winter, this frost-proof drain valve should be selected as it can effectively prevent valve body freezing and clogging faults.

FAQ

Q: Can the drainage valve be opened while the vehicle is in motion? How long should the drainage process last?

A: It is not advisable to keep the valve open for a long time as it will deplete the braking air pressure. It is recommended to drain for 1 to 2 seconds at a time. The ECU automatically controls and suggests draining once every hour.

Q: How long does it take for the ice at -40℃ to melt?

A: When the valve body is completely frozen at -40℃, it takes 3 minutes of power heating to melt the ice at the valve opening, and 5 minutes for the temperature of the valve body to rise above 0℃.

Q: Will using a high-pressure water gun to clean the chassis cause damage to the valve body?

A: With an IP68 protection rating, the product will not be damaged if the water gun is kept at a distance of over 30cm when cleaning.

Q: What situations are not covered by the warranty?

A: Installation with excessive torque causing damage to the valve body, water ingress in the oil causing damage, unauthorized disassembly, and external force-induced damage are not within the warranty scope.
