Who can provide the calculation process for selecting control valves
Thread Content
The forum provides basic information on control valves as well as calculation formulas for selection. For a specific process flow, the pressure before the valve is known, but how is the pressure after the valve determined? Could some expert tell me? Thank you! It would be best to provide a simple selection calculation process for reference.
The pressure behind the valve is also specified by the process engineering team; they determine the pressure difference based on the design pressures of the containers on both sides
