[Dineshkarthisan]

Hi all,
good day!!!
Please find the attached image for the detailed problem.how to determine the area of the ball and at which area of the ball the pressure acts???
Please help me in guiding to design the ball type check valve .provide me any sample calculation and procedures for the design of Ball type check valve.

thank you,..

hint - It's a very simple trigometric solution.
Pressure acts in all directions at the same time.

Ignore the curvature of the ball and simply work out the area from one side of the V where the ball touches to the other.

Thanks for ur reply.

i have solved the problem with 15.32mm diameter as the pressure acting area(please find the attached image)

tell me whether the dia i have taken is right or wrong.

Thank you.!!!

I believe that is correct.

This is though the pressure that the first bit of fluid passes the valve. Once you try to get more flow then other parameters start to come into play
