Our professional air compressor blowdown valve / automatic drain valve is designed for 24-hour continuous operation of screw compressors, air tanks and pipeline systems. It realizes automatic draining, zero air loss and anti-block performance, solving common industrial draining problems thoroughly.

• Automatic Sensor Drainage: Precisely senses liquid level, automatically opens for draining when water accumulates and closes tightly after emptying. No manual operation needed, keeps air tanks and pipelines dry all the time and effectively reduces compressed air moisture content.

• Zero Air Loss & Energy Saving: Perfect sealing after closing completely eliminates continuous air leakage, avoiding repeated compressor reloading. It steadily saves 10%-15% power consumption, bringing obvious long-term energy cost reduction.

• Anti-Clog & Anti-Oil Pollution: Equipped with large-diameter drainage channel and built-in filter structure to block oil sludge, rust and dust. The valve core operates flexibly without jamming, reducing failure rate by 90% and adapting to harsh industrial working conditions.

• High Pressure & Explosion Proof Structure: Precision aluminum alloy / stainless steel valve body is high temperature and pressure resistant, with rated pressure up to 1.6MPa. No deformation or cracking under long-term high-pressure operation for long service life.

• Leak-Proof Premium Sealing: Imported oil and high-temperature resistant sealing rings resist corrosion and aging. Passed millions of opening-closing fatigue tests with zero leakage, protecting compressor filters, main engine and downstream pneumatic equipment.

• Universal Direct Replacement: Standard NPT/G thread interface, 1:1 compatible with Atlas Copco, Sullair, Ingersoll Rand and all screw & piston air compressors. Fast 5-minute installation without modification.
