Automatic air supply device is composed of a two bit three electric ball valve, two manual ball valve, check valve and safety valve assembled by automatic or manual control loop to achieve automatic or manual air supply or closed turbine generator for maintaining hydraulic device or other energy storage system is required for gas-liquid ratio in normal work.

Safety valve automatic air supply device is special, it is in the open or closed pressure is less than 3kg/c square meters, sensitive action. When the accumulator pressure is too high, the safety valve automatically opens, exhausts outwards, and makes a noise warning. When the accumulator pressure drops to the rated pressure, the safety valve is closed and the exhaust air is stopped.

•  It adopts ball valve plate structure to realize zero pressure differential work
•  The air flow rate is large, and the air supply time is longer
•  The degree of integration is high and the volume is small
•  Good sealing performance
•  With manual feeding and exhaust function
•  The device is equipped with a safety valve, which can protect itself
•  The driving part adopts imported parts, and the action is accurate and reliable
•  The whole set is made of stainless steel with excellent corrosion resistance
