Pneumatic positioners ПП (hereinafter – ПП) are designed to reduce the misalignment of stroke and increase the rapidity of one- and two-way piston reciprocating and rotating pneumatic actuators and membrane pneumatic actuators by introducing feedback in response to the position of the actuator output element.

Scope of application of ПП includes automatic process regulation or remote control systems in pulp-and-paper, oil refining, petrochemical, and other industrial sectors.

ПП are component parts for actuators.
