Jim,
Thanks for the reply and your example.
If the bolts are not loaded enough to hold the two flanges together, then they are not tight enough. They need to be tight enough to hold the forces applied to the flange by the weight of the valve. How tight is that?
I can convert between...
The valve is a quarter turn valve with the actuator mounted off of an ISO pad around the stem area. The body is a single piece and is strong enough to ignore any minor deflection in the body. To simplify the problem, I was combining the force as a single force in line with the stem axis (18...
I have an end of the line valve with a 4" 300# flange with the standard 7.88 dia BC, with (8) 3/4" Bolts. The Valve is requiring a large actuator that will apply a large weight to the valve.
This setup is a cantilever beam with a support at the bolted connection and the weight applied...
