Suppose the pilot pressure range is from 3 to 15 psig for the illustrated pneumatically-operated diaphragm-actuated control valve. Assuming the control valve is trimmed for a linear response and the travel position indicator is calibrated in percentage, what would the approximate valve position with a 9 psig pilot pressure?

This is an interesting question about control valve operation! With a pilot pressure of 9 psig, which is midway between the 3 to 15 psig range, you can expect the valve position to be approximately 50% if it’s calibrated for linear response. Understanding these relationships is key for effective system control.
