(1)Used in important regulating systems with high requirements for
regulating quality to improve the positioning accuracy and
reliability of regulating valves.
(2)Used in the occasion where the pressure difference between the
two ends of the valve is large ( â–³p>1MPa). Increase the output
force of the actuator by raising the pressure of the air source to
overcome the unbalanced force generated by the liquid on the spool
and reduce the travel error.
(3) When the regulated medium is high temperature, high pressure,
low temperature, flammable, in order to prevent external leakage,
the packing is often pressed very tightly, so the friction between
the stem and the packing is large, and the time lag can be overcome
with the positioner at this time.
(4)When the regulated medium is viscous fluid or contains solids in
suspension, the positioner can overcome the resistance of the
medium to the movement of the valve stem.
(5) Used for large-diameter (Dg>**0mm) regulating valves to
increase the output thrust of the actuator.
(6)When the distance between the regulator and the actuator is
above *0m, the positioner can be used to overcome the transmission
lag of the control signal and improve the action response speed of
the valve.
(7) It is used to improve the flow characteristics of the
regulating valve.
(8)When a regulator controls two actuators to implement split-range
control, two positioners can be used to accept low signal and
high signal respectively, then one actuator low range action
and the other high range action, which constitutes a split-range
regulation.
