Installation location of swing check valve
Thread Content
Everyone, may I ask if a swing-type check valve can be installed in this way? I don’t think it’s possible

The swing-type valve relies on the weight of its own lifting element to close the check valve; isn’t that a problem?
For a check valve with such a high pressure rating, with this type of installation, what you need to do is submit a written report to the installation team and the design team, as well as to the project manager, so that they can pay attention to this issue; it should then be possible to resolve it. According to the factory instructions that come with this valve, or by contacting the manufacturer to request installation instructions for reference.
Looking at Fran, the pressure level is also high. It is not recommended to install it this way. Is the purpose of installing it this way to redirect flow in order to avoid the actuating mechanism above the control valve? I remember that for check valves, there are no requirements regarding the position before or after installation; perhaps it would be possible to swap the positions of the two valves. Or check the location of the stop valve in the process flow diagram.
Installing it in this way definitely won’t work. When a rotary valve is installed in such a manner, it will be difficult to close it properly later on; it may not be able to be closed at all, or some materials might stick to the valve and prevent it from closing. Personal suggestion
No, the valve disc cannot be pressed tightly enough, so it cannot perform its check function
Why can’t I see the pictures I sent? Can you see clearly?
