Questions regarding the concepts of valve back pressure and maximum pressure difference? I’d like to ask the experts here. Thank you in advance
Thread Content
When I first started working with valves, I was confused about a few concepts. 1. What is the maximum pressure difference for a valve? 2. What is the nominal pressure of the valve? 3. Back pressure of the valve. What do these three terms refer to respectively? ? If it’s a copy, then please don’t send it. I prefer simple and easy-to-understand explanations. Thank you
No one answered! ! I’ll say a few words; I’m not sure if it’s appropriate. 1. Valve pressure difference: This should refer to the pressure difference on both sides of the valve disc when the valve is closed. 2. Nominal pressure of the valve: It refers to the nominal pressure of the medium. It is the operating pressure after taking into account the safety factor. 3. Back pressure: This is unclear. It’s probably the pressure difference when the pressure on one side of the valve plate is 0
