12 MPa before the valve and 13 MPa after the valve; hydrogen, DN50 diameter; gate valve – what is the shortest possible time for opening and closing?
What manufacturing process is this? Is hydrogen flowing in reverse? The question is too vague; at the very least, what type of valve? Drive method, actuator? Get information like that! What are the process requirements? :lol
Hydrogen backflow – any type of valve will do as long as it meets the requirements. The shorter the process time, the better; ideally, it should be able to open and close in one second
Pneumatic ball valves should be the fastest to respond; it should take no more than 3 or 4 seconds from when the DCS signal is sent to when feedback is received, and in practice the response time is around 2 seconds.
Done this way, the valve will fail after not long
