The variable angle valve adopts a completely new structure, consisting of two parts: the switch and connector. When installing, the hose is connected to the joint first, and then the joint can be fixed to the angle valve switch by rotating 60 degrees, making the installation more convenient. The angle valve can adjust by 360 degrees in different scenarios. A single water outlet can now become 4 different products: angle valve, filtering angle valve, single faucet and washing machine taps, reducing the development cost and cycle, thereby increasing the economic benefit.
