Technical help: Who has information on automatic water release valves

Since it is located in the north, the pipelines above ground need to be drained in winter to prevent freezing; however, I don’t have any information on automatic drain valves. Has anyone used them? What is the model, and what is the nominal diameter? Is there one at 1.6 MPa? Thank you first
An anti-freezing automatic drain valve consists of a valve body that can be integrated with the water tank, as well as a valve plug located within the valve body. Inside the valve body’s interior cavity, a memory alloy spring exerts pressure on the valve plug to close the water outlet; meanwhile, a conventional compression spring also exerts pressure on the valve plug in the opposite direction. When the water temperature exceeds the set drainage temperature, the elasticity of the memory alloy spring is greater than that of the conventional compression spring. The drain valve in this design can replace various existing drain valves; it is installed on the water tank or cylinder and will automatically release water before the water temperature drops to the freezing point, thus preventing the tank or cylinder from cracking due to freezing.
Are there any details such as model and size? I mainly use it on pipes
