It needs to be distinguished as saturated or unsaturated; if it is saturated, hardening treatment is advisable, using materials such as 17-4 and 440

Additionally, it depends on the design of your piping system; the material of the valve bodies should be no lower than that of the pipes. Can you do it? Generally, one needs at least 3 years of experience before being allowed to produce drawings on their own.
