Identify valves by looking at pictures

I would like to ask the experts here: what kind of valve is this? What is the specific working principle? How to use it? Please let me know! !
It’s a safety valve or a check valve, which uses the gravity of a weight to control the opening and closing of the valve.
Confirmed, a check valve is also known as a non-return valve
This should be the HH47X butterfly cushioned check valve
The slow-closing check valve, also known as a non-return valve, serves to prevent the backflow of fluid in the pipeline. Its working principle is as follows: 1. Principle of operation: The up and down movement of the cylinder plunger helps the valve disc to open and close quickly, thereby ensuring proper sealing. 2. Structural details: 1) Type of structure: Rotary single-disc valve; 2) Driving method: Welded connection; 3) Connection type: Welded connection. 4) The opening and closing of the valve are controlled by a pneumatic device, which speeds up these processes.

Is this pneumatic? I thought it was hydraulic; that small device over there looks a lot like the hydraulic system of a jack! !
