Do the wing valves of the anti-restart system need to be replaced every time they are serviced?

Do the wing valves of the cyclone separators in the catalytic cracking reactor-regenerator system need to be replaced every time they are overhauled? (We need to replace the centrifugal flap valve of our settler with a new one every time.)

We haven’t replaced the wing valves on our regenerator in many years
It depends on the condition of the valve; of course, it would be ideal to replace it each time.
It mainly depends on the wear condition of the flap valve; flexibility adjustment of its opening angle is required every time before starting operation!
The main checks involve verifying the flexibility of the valve plate, measuring the angle of the flap using an angle gauge, and checking for any worn grooves on the valve plate; if everything is normal, there is no need to replace it
Just in case, here we replace the wing valves of the settler whenever there is a periodic shutdown for maintenance, whether it’s good or bad. Wing valves shouldn’t be expensive, right?
The wing valves of our regenerator have not been replaced for many years either; only the wing valves of the settler are periodically inspected and replaced.
We can just replace it with a new flap valve; a simple flap valve shouldn’t be expensive either
The finance school has a rough attitude; I have no objection – it’s fine!
The price is around 20,000 yuan, for DN325
