Reliability: "Unbalanced" air valve ensures no-stall operation; 5. Serviceability: Easy access to ball checks and fluid caps for maintenance and repairs..【Working Principle】- Each working chamber equipped with a diaphragm. Compressed air from the pump inlet into the valve, through the valve body to introduce compressed air into one of the chamber, while the other chamber gas emissions. Once the end of the stroke is reached, the gas distribution mechanism automatically introduces compressed air into the other working chamber to push the diaphragm in the opposite direction so that the two diaphragms move back and forth in unison..【Avant-garde Design】- Exquisite appearance, compact structure, easy to operate and carry, made of high quality material, strong and durable, ensures long service time.
