Rotork - Model CK -CK range

CK: Standard isolating duty, multi-turn electric actuator.CK actuators can be retrofitted/upgraded, by adding a Centronik control module to provide intelligent valve automation. Torque range: × The tripping torque is independent adjustable for directions OPEN and CLOSE within the range (100%-40%). × Isolating: Short-time duty S2 - 15 min, and S2-30 min, refer to motor technical datasheet for details × Modulating: S4-25% and S4-50%, refer to motor technical datasheet for details Motors: × Motor protection: Self-resetting thermo-switches embedded in the motor windings which are designed to trip as soon as the motor temperature exceeds +132 ºC. Once the motor has cooled to normal operating temperature, the thermo-switch will reset and electrical operation can resume. × Insulation class F, tropicalized (H, under request). × 3-phase AC Isolating/Modulating Duty, available voltage and frequency: 220V, 240V, 380V, 400V, 415V, 440V, 500V, at 50 Hz/60 Hz
