Take a look, what kind of valve is this?

Does anyone know what kind of valve this is and how it works?
The JD745X multi-functional water pump control valve consists of a main valve, a control valve, and a piping system. The valve body is of the direct-acting type, while the main valve’s control chamber adopts a diaphragm or piston-type dual-control chamber structure. This additional control chamber provides enhanced control over the main valve, enabling functions such as slow opening, full opening, slow closing, and shutdown of the water pump outlet. In this way, one valve can achieve multiple control functions for the water pump outlet through a single adjustment. This product is used in the pump outlet pipelines of water supply systems in high-rise buildings and other water supply systems to prevent and reduce water hammer effects in the pipelines when the pumps start or stop operating, to prevent backflow and protect the pumps, and to ensure the safety of the pipelines.
I agree with what was said on floor 3; it’s a pressure control valve
Reply to 3# shzdlzt: What was said on the third floor is correct – it’s the multi-functional water valve used in our fire protection systems
What? Put nicely put, it’s just a more complex one-way valve； Two additional pressure tap tubes and a diaphragm at the top. Generally used at the outlet of circulating water and fire pump systems
The JD745X is a multi-functional pump control valve. Its purpose is to be installed on the pump outlet pipes of water supply systems in high-rise buildings as well as other water supply systems, in order to prevent backflow of the fluid and to avoid the occurrence of water hammer effects. This valve combines the functions of an electric valve, a check valve, and a water hammer suppressor, thereby effectively enhancing the safety and reliability of the water supply system.
The JD745X is a multi-functional water pump control valve that combines the functions of an electric valve, a check valve, and a water hammer suppressor; it is typically used at the outlet of circulating water and fire pump systems
It’s just a one-way valve; its function isn’t complicated at all
A multi-functional hydraulic valve that acts as a check valve and is installed at the pump outlet to prevent water hammer.
