More control for this electric valve actuator
This company has increased the versatility of the CK range of modular electric valve actuators with the introduction of the CK Atronik (photo), an intermediate-level integral control option, providing a ready-to-operate 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. Connection to a suitable power supply is all that is required for local operation of the actuator. Digital microprocessor-driven functionality delivers reliable motor control for isolating, regulating or modulating valve duties. Integral local-control selectors are provided, together with clear LED status indication of valve open, valve closed, valve moving and alarm. — Rotork plc, Bath, U.K.
