VALVES (Actuator, Control, Motorizes, Positioner)

AD/AR/AL
Electric Actuators

Model: WM-VLS-SMR-001

Electric Actuators are electromechanical devices that are highly reliable in replacing the manual operation of valves in:

• Remote or hazardous locations.
• Applications demanding high actuation torque.
• Valves requiring quick positioning, particularly those with large numbers of turns Automatic process control applications where valves operate in two limit positions, or intermediate repositioning (modulation).

Smar Actuators are available for dampers, gate, slide, diaphragm, globe, butterfly, ball and plug valves. Four torque ranges from 150 to 1850 Nm (AD model ) / 20 to 80 Nm (AR and AL models), and rotations from 6 to 48 rpm are available. Higher torque may be obtained by adapting additional gear stages coupled to the output shaft of the actuator.

All models are equipped with an overload protection system for valves operating in limit positions, or in the case of foreign objects obstructing their travel. These are automatic systems that turn off the motor, protecting the actuator/valve system.

As an option, valve position and travel transmitting devices can be supplied with the actuators, providing an operational status for each actuator/valve set. In case of power failure, all actuators are capable of manual operation by means of a hand-wheel attached to a mechanical coupling. Such coupling will deactivate upon electric motor start-up.

This Actuators provide the following characteristics:

• Easy operability.
• Ruggedness.
• Long service life.
• Internal parts protected against aggressive environments.
• Easy maintenance.
• Accurate positioning.
• Available options include explosion proof enclosures, fail-safe operation and proportional control.
• Attachments are in accordance with ISO 5211 and DIN 3337. Such characteristics fulfill the most important requirements in the following applications.
• Oil refineries.
• Petrochemical plants.
• Sugar and ethanol mills.
• Food industries.
• Pharmaceutical industries.
• Chemical plants.
• Cement and steel mills, and glassworks.
• Water, natural gas and oil pipelines.
• Sewage stations and water treatment stations (sanitation).
• Oil drilling rigs and production platforms.
• Air conditioning units.
• Pneumatic dispatch lines.
