Function of locator
1, used in important regulating systems with high quality requirements, to improve the positioning accuracy and reliability of regulating valves.
2. When the pressure difference between the two ends of the valve is large, the output force of the actuator is increased by increasing the pressure of the air source, so as to overcome the unbalanced force generated by the liquid on the valve core and reduce the stroke error.
3. When the regulated medium is high temperature, high pressure, low temperature, toxic, flammable and explosive, the packing is often pressed tightly to prevent leakage, so the friction between the valve stem and the packing is large. At this time, the time lag can be overcome by using the locator.
4. When the tuned medium is viscous fluid or contains solid suspended matter, the positioner can overcome the resistance of the medium to the movement of the valve stem.
5. It is used for increasing the output thrust of the actuator with large caliber (Dg> 100mm).
6. When the distance between the regulator and the actuator is more than 60m, the positioner can overcome the transmission lag of the control signal and improve the response speed of the valve.
