Rotork Electrical Actuators are designed for automated valve operation across industrial process and infrastructure applications.

Electric actuators can provide reliable local or remote control of valves and are available for different operating movements, including multi-turn, part-turn and modulating applications.

Rotork’s electric actuator portfolio includes intelligent and industrial actuator technologies designed for dependable valve control across applications such as:

• Water and wastewater
• Power generation
• Oil and gas
• Chemical processing
• Industrial manufacturing
• Marine applications
• Infrastructure
• Energy facilities

The appropriate actuator should be selected based on required torque or thrust, valve movement, duty cycle, operating speed, control system and environmental conditions.

Applications involving smaller valves or restricted installation spaces can benefit from Rotork Compact Electrical Actuators.

Compact actuator solutions offer electrically powered valve automation while reducing the space required around the valve assembly.

They can be applied to suitable ball valves, butterfly valves, dampers and other quarter-turn flow-control equipment.

Rotork Rotary Actuators provide rotational movement for equipment requiring quarter-turn operation.

Typical applications include:

• Ball valves
• Butterfly valves
• Plug valves
• Dampers
• Other quarter-turn process equipment

Rotary actuator selection must be coordinated with the valve torque requirement to ensure reliable operation throughout the complete opening and closing cycle.

Rotork HVAC Actuators provide automated movement for valves and dampers used within heating, ventilation and air-conditioning systems.

Rotork’s HVAC actuator portfolio includes rotary and linear actuator technologies suitable for building automation as well as demanding industrial HVAC installations.

These actuator solutions can support applications involving:

• Air handling systems
• Ventilation systems
• Fire and smoke control
• Dampers
• Heating and cooling valves
• Industrial ventilation
• Building automation

Where accurate regulation of process flow is required, Habonim Control Valves and Habonim V-Notch Ball Valves can be incorporated into automated control systems.

The characteristic profile of a V-notch ball makes these valves particularly suitable for applications where more controlled flow modulation is required rather than simple open-and-close operation.

Valve selection can be coordinated with suitable actuation and control accessories to create an integrated automated valve package.

Large process valves and critical applications require actuator systems capable of handling demanding torque requirements and difficult operating environments.

Rotork Heavy-Duty Actuators are designed for these applications.

The Rotork heavy-duty fluid actuator portfolio includes pneumatic and hydraulic technologies for demanding quarter-turn valve operation. Products such as Rotork’s GP/GH range use scotch-yoke mechanisms for on/off and modulating quarter-turn duties.

Heavy-duty actuator systems can be considered for:

• Large pipeline valves
• Oil and gas facilities
• Petrochemical processing
• Power generation
• Water infrastructure
• Emergency shut-down systems
• High-torque valve applications

Where direct manual or powered operation of a valve is difficult because of the torque required, a Rotork Gearbox can provide the mechanical advantage necessary for dependable valve movement.

Rotork provides gearbox solutions for both part-turn and multi-turn applications.

Rotork Part-Turn Gearbox

A Rotork Part-Turn Gearbox is designed for valves requiring limited rotational movement, normally approximately 90 degrees.

Typical applications include:

• Butterfly valves
• Ball valves
• Plug valves

Rotork offers numerous part-turn gearbox families covering general industrial through heavy-duty valve applications.

For example, Rotork’s AB range comprises heavy-duty part-turn worm gearboxes suitable for ball, plug and butterfly valves used across water, gas, chemical, power and other industrial applications.

Rotork Multi-Turn Gearbox

A Rotork Multi-Turn Gearbox is used where the valve requires several rotations to move between open and closed positions.

Typical applications may include:

• Gate valves
• Globe valves
• Sluice gates
• Dampers
• Other multi-turn equipment

Rotork offers dedicated multi-turn gearbox ranges for different torque and application requirements.

The correct valve automation package is determined by the movement and torque required by the valve rather than by actuator type alone.
