Electric Actuators and Control Systems

Rotork - Model IQ - Multi-Turn Third Generation Intelligent Electric Actuator

IQ3 Range multi-turn electric actuators can be used for isolation or regulating duties of up to 60 starts per hour.

Rotork - Model CK - Standard Electric Actuators

CK range actuators are suitable for valves in non-hazardous locations. The modular product range facilitates a number of different control package configurations to meet your application requirements. • Modular design provides an off-the-shelf solution for spares and upgrading • Plug and socket connection for easier field wiring • Continuous valve position indication even during power loss • Non-intrusive setting via infrared or optional Bluetooth with the intelligent CKc - Centronik module • Hollow output drive to accept rising valve stems • Detachable base options • Secure, padlockable, manual handwheel drive fully independent of the motor drive train • IP68 rating (8 m for 96 hrs) • Direct output torque range:10 - 500 Nm (7 - 369 lbf.ft) • Max. torque with standard multi-turn gearbox:6,750 Nm (4,979 lbf.ft) • Max. torque with standard part-turn gearbox: 205,600 Nm (151,600 lbf.ft) CKQ Part-turn actuator performance • Direct output torque range:54 - 1,000 Nm (40 - 738 lbf.ft)

Rotork - Model ExMax Range - Part-Turn Explosionproof Actuators

Compact, robust and lightweight electric part-turn valve actuator, designed for use in Ex areas for all gases, mists, vapours and dust.

Pakscan - Classic Field Network Add In Module (AIM)

Proven Control System: The Pakscan™ Classic redundant loop network has been the network of choice for actuator control for over 30 years. Using robust current loop technology, up to 20 km loop lengths and 240 field devices are possible.

Rotork - Model CK Atronik - Electric Actuators

The Atronik control module adds an intermediate level integral solution to the modular CK range. CKA - Atronik isolating duty actuator. CKRA - Atronik modulating duty actuator. It offers modest control and feedback, and optimises the integral starter approach to offer simplified electronics, creating a robust control package for CK actuators.

Rotork - Model Q - Part-Turn Actuators

Small, electro-mechanical part-turn actuator environmentally sealed to IP68.

Rotork - Model IQM - Multi-Turn Modulating Electric Actuators

The modulating version of the IQ 3-phase electric actuator has a solid state reversing starter in place of the electro mechanical contactors. It features fast-response remote control circuits for rapid control. To optimise positional control, the solid state starter also adds an electronic motor ‘brake` feature.

Rotork - Model ExMax+Lin/ExRun - Linear Explosionproof Actuators

ExRun and ExLin electric linear valve actuators are designed for use in Ex areas for all gases, mists, vapours and dust. Linear conversion for safety applications (Fail-safe function) in combination with ExMax.

Rotork - Model IQML - Linear Modulating Electric Actuator

Benefiting from all the features of the IQM 3-phase electric actuator, the IQML has a linear output drive providing seating thrust output of up to 43 kN (9,667 lbf).

Rotork - Model ExCos/ExBin - HVAC Explosionproof Sensors and Switches

ExCos analogue sensors and ExBin binary switches are designed for direct use in hazardous locations. No additional modules in the panel required. No intrinsically safe wiring required. All parameters adjustable on site without additional tools or measuring devices. Sensors and switches for pressure, differential pressure, temperature and humidity available, Explosionproof design for all gases, mists, vapours and dust.
