July 3, 2019 - Rotork has introduced the CK Atronik, an intermediate level integral control option, providing an actuation solution to meet the standard requirements of many plant specifications.
The CK Atronik control module houses a reversing contactor starter with mechanical and electrical interlocking, a Rotork design for electric actuation. Connection to a suitable power supply is all that is required for local operation of the actuator.
Digital microprocessor driven functionality delivers motor control for isolating, regulating or modulating valve duties. Configuration is achieved with on-board dual in-line switches. Integral local control selectors are provided, together with clear LED status indication of valve open, valve closed, valve moving and alarm. Mechanical valve position indication is also provided on the actuator gearcase. Options include analogue control for positioning, analogue feedback, additional relay and network bus connectivity.
All CK modular actuators are environmentally sealed to IP68 (8 metres for 96 hours) as standard for reliability in harsh operating conditions. Plug and socket connections for power, control and between modules assistswift site wiring and maintenance. Manual handwheel operation is independent of the motor drive and selected with a lockable hand / auto lever acting on a safe, low speed clutch. Separate thrust or non-thrust bases are available, enabling removal of the actuator from the valve without affecting valve position.
