Description for Rotork CKR Standard modulating duty actuator

Comprising electric motor, drive gearing, independent handwheel drive, torque and position limit control & indication with plug and socket field wiring connection. The CK range provides the right solution for users with centralised motor control centres or for high temperature and sustained vibration applications.CK - Standard isolating duty actuatorCKR - Standard modulating duty actuatorModular DesignThe major components of the CK range are modular; speed changes, control package upgrades and indication outputs can be altered to suit the user’s exact requirements. CK actuators can be adapted to meet user specification quickly and efficiently to achieve fast turnarounds and quick delivery.IP68 Watertight ConstructionAn IP68 (8 metres - 96 hours) rating is achieved using spigot and O-ring joints for actuator covers and between modules.Temperature Range OptionsThe standard range is rated for -30 to +70 ºC (-22 to +158 ºF). Low temperature option available between -40 and +60 ºC (-40 to +140 ºF) with a change of lubricant and bearings.International StandardsCK range products comply with international design standards, actuator standards EN15714-2, EN ISO 5210 , MSS SP 102 and manual handwheel operation standard EN12570.Plug and Socket ConnectionPower, control and indication wiring is connected into a plug located in the terminal cover allowing simple mechanical connection / disconnection of the actuator. Plug and socket connections between actuator modules provide a simple connection platform for adaption and field upgrades.Double-sealingThe IP68 enclosure protection is maintained even whilst the actuator terminal housing is removed by using a double sealing system around both parts of the plug and socket connection.Torque Protection and Position LimitsThe Rotork CK actuator includes torque measurement and independently adjustable torque limiting, for both open and close control. This ensures precise valve control whether by position limit or torque seating. Torque limiting protection is available mid-stroke to prevent valve damage should the valve be obstructed. Simple mechanical limit and torque adjustment is provided for the CK Standard and position changes are still measured during power loss.
