SR-CCK positioner is designed for the proportional operation of rotary single or double acting actuators, to actuate butterfly, plug, ball valves, etc. It is usually located in the control circuit between the regulator and the actuator of the final control element (pneumatic rotary single or double acting actuator).
This product amplifies pneumatic signal to eliminate the functional or parasite drag of the final control element and increase its speed of response.
It also determines the actuator position according to the linear or non-linear function of the control signal. The SR/CCK checks the functional sequential of different actuators using a single control signal.
