Actreg – Technical profile of a pneumatic actuator manufacturer for quarter-turn valves

Actreg is a manufacturer of pneumatic actuators used for automation of quarter-turn valves such as ball valves, butterfly valves and plug valves. Its high-performance actuator catalogue refers to pneumatic actuators with traceability of critical components such as body, end caps, stems and pinions, with individual marking of heat numbers.

Actreg actuators are used in valve automation packages where a manual quarter-turn valve must be operated remotely or integrated into a control or shutdown sequence.

Main technical areas include:

• rack-and-pinion pneumatic actuators,
• double-acting actuators,
• spring-return actuators,
• ISO 5211 valve mounting,
• NAMUR solenoid valve interface,
• accessories for On/Off valve automation,
• SIL / safety-related applications depending on model and project documentation.

Double-acting actuators require compressed air for both opening and closing movement. They are suitable where fail position is not required or where the fail action is handled externally. Spring-return actuators use compressed air in one direction and spring force in the other; they are selected when a defined fail-open or fail-close position is required.

The actuator must be sized from valve torque, not only from DN. Required torque data include:

• breakaway torque,
• running torque,
• seating torque,
• maximum differential pressure,
• seat material,
• service temperature,
• valve ageing or deposits,
• required safety factor.

For process valve automation, the actuator package normally includes actuator, NAMUR solenoid valve, limit switch box, air filter regulator, mounting kit and coupling. Each element must be compatible with the required fail position, opening / closing time, hazardous area classification and control system interface.

Actreg actuators are relevant for valve application engineers, automation engineers, maintenance teams and skid manufacturers working with pneumatic On/Off valve packages.
