Could you please explain what this means? ?

Safety valves, DN25, 1.2 Mpa, 2 units. Are these parameters detailed enough?
It’s not very complete; the valve model and material should be determined. Example: Butterfly valve D343H-10C, DN200, material cast steel. Thus, the valve is determined.
Reply to 3# xujinjiang: First, thank you for your reply. I would like to ask again – could you use the parameters I provided to help me determine what type of safety valve it is?
Reply to 4# zhaogaoyu2008: It would be best if you could clarify what stage this is in. Under normal circumstances, in our process, the process engineering team provides the parameters to the manufacturing factory (we generally do not calculate the safety valves), and the manufacturing factory then supplies an appropriate model of safety valve to the piping engineering team.
It is also necessary to know the model or connection method of this safety valve, as well as the material of the valve.
Reply to 1# zhaogaoyu2008: There is still a long way to go. In addition to the model, the safety valve also requires parameters such as the setting pressure and the trigger pressure; otherwise, the manufacturer cannot produce it!
Reply to 6# Chuan Nao Liao Kun: Isn’t 1.2Mpa the starting pressure?
Safety valves, DN25, 1.2 Mpa – 2 units. All that is known is that the nominal diameter of the valves is DN25, the pressure is 12 MPa, and there are 2 units in total. The connection type and seal type should be the same as those of the connecting components specified in the design (pipes, equipment interfaces). What are the available options for selecting safety valves? Parameters such as set pressure and trip pressure also need to be provided.
It would be best to provide the medium as well, along with its condition, etc
Reply to 8# Hsinchu: Thank you for your reply. I would like to ask further – since this safety valve is intended for use in marine boilers, can we determine what type of product is required based on that?
The starting pressure is calculated based on the design pressure of the container; it’s not called starting pressure but rather return pressure. When this return pressure is reached, the device starts to function
