hello,
i am new to the valves engineering market and i am trying my best to check for different matters pertaining to this field.
within my reading of API-598 i noticed that the seat test for the butterfly valves (API-609 Category A) can be performed from only one side though its not marked (arrow indicated), here for the bi-directional valves how can be sure that we tested the correct side where the flow is creating the most/severer conditions which is the up-stream side?
can you please advise
thanking for your answers
