Control Valve and Diaphragm Actuator Force Calculation

[neroverdi41]

Hello Friends;

How can I calculate the force that the flow control valve will produce? At the same time, how can I determine the actuator I need to put on it? For example, there is 14500 N valve force, how can I determine the dimensions of the actuator's casings? How can I calculate the effective diaphragm area? How can I calculate the required spring force?

Where did that number come from? Looks very big.

Do you have a drawing of the valve?
