What does “Reduced Trim” specifically mean for the valve spool type listed in the control valve data sheet? Does it mean that the diameter of the valve core is smaller than the process connection diameter of the valve body? Avoid excessive reduction in the valve body diameter
It refers to the situation where the diameter of the valve core is smaller than that of the flow channel in the valve body; in other words, the valve body does not have a reduced diameter, while the valve core does.
