FAQ
- Linear trim gives equal flow change per equal stem movement, good for level control where the loop gain is roughly constant. Equal-percentage trim gives small flow changes near closed and bigger changes near open, which compensates for the way pressure drop redistributes in a system as the valve opens. Most pressure, temperature, and flow loops want equal-percentage.
- A positioner watches where the valve actually is and pushes the actuator until it matches the controller's setpoint. Without one, packing friction, varying line pressure, and actuator hysteresis all conspire to put the valve in the wrong spot. Any control valve worth installing has a positioner on it.
