WBK-20 Zero Loss Auto Drain Valve 1/2" for Air Compressor Tank Dryer Filter

- Automatic Drainage: Adopting a pure mechanical structure, it relies solely on the pressure control of compressed air to open and close, and can automatically drain without the need for an external power supply. The drainage process does not waste compressed air, significantly reducing the operating cost of the air compression system.
- Double Filtration Structure: equipped with double-layer filters, this automatic drain of the gas storage tank can effectively block particles and impurities from entering the valve port. The filtering design ensures smooth and unobstructed drainage during long-term use.
- Anti Blocking And Anti Freezing Design: The automatic drainage valve is equipped with an anti blocking structure, and impurities are automatically flushed out with the drainage, making it less likely to get stuck due to rust deposits. It is not easy to freeze and crack in sub zero low temperature environments.
- No Electricity Needed: The automatic drainage valve adopts pure pneumatic mechanical control, no wiring is required, and the installation position is flexible. No vulnerable electronic components such as solenoid valves and timers, with a failure rate close to zero, and long-term maintenance free operation.
- 1/2" Standard Connection: equipped with a 1/2 inch threaded interface, it can be directly installed on the drainage outlet of gas storage tanks, filters, dryers, and oil-water separators. Complete supporting connectors, easy installation, suitable for various compressed air systems.
