Selection of control valves
Thread Content
How are the pressure before and after the control valve determined? Is it the pump that is located before the valve? Is the output pressure of the pump equal to the pressure before the valve? It’s the tank behind the valve; so how is the pressure behind that valve determined? Please ask the experts for advice!

But if you need to choose how to design the valves, it’s better to have the relevant technical departments handle it.
The pressures before and after the valve are determined by the process based on actual conditions. With your vague questions, it’s difficult to explain things clearly to you. But what you described is probably fine. Analyze each specific situation individually.
