About butterfly valve plate and valve stem connection

I have a client in Philippines told me that rival the valve plate and the valve stem is connected by bolts, and our products are connected with a taper pin, please tell me the advantages disadvantages of Comrade conical pin connection and bolt connection. Thank you all

Answer:

If the bolts were rusted inside, they would not be available unless they were bolted with white steel bolts! Bolt connections will have momentum, and for a long time the bolts may be fatigued and fractured!

The taper pin is easy to remove and can only be installed in the same direction.

But the taper pin needs to be loosened, or there will be a risk of natural shedding!
