Automatic water replenishment and injection valve is a new type of valve installed on the water replenishment pipeline of closed cycle heating or cooling systems. It was researched by Shanghai Anchao in 2002. The automatic water replenishment and injection valve can automatically maintain the system pressure at the set value, and the check valve inside the valve can prevent hot water from flowing back into the cold water pipeline of the heating system.

The pressure value can be adjusted in conjunction with a pressure gauge and automatically maintain the adjusted system pressure; When the system pressure drops, the automatic water injection valve, also known as the constant pressure water injection device, automatically opens to inject water and closes when the set pressure is reached to prevent damage to system equipment caused by high water pressure.

The visual automatic water replenishment valve is a new type of valve installed on the water replenishment pipeline of a closed cycle heating or cooling system. It is a high-tech new valve that integrates the functions of a pressure reducing valve, a shut-off valve, a check valve, and a filter.

The AF0522 series visual automatic water replenishment valve with a scale has a vertical water replenishment pressure adjustment scale display. Its vertical scale can completely avoid the pressure value deviation caused by the pointer position of the dial scale moving incorrectly.
