Allen-Bradley 2R2500DAR Pneumatic Valve Actuator

Description:

The TRIAC Controls 2R2500DAR Pneumatic Actuator is used in automated quarter-turn valve systems to provide reverse-acting pneumatic actuation for industrial process valves. Commonly installed on ball valves and butterfly valves in chemical processing, water treatment, oil and gas, power generation, and manufacturing facilities where reliable automated valve control is required. Maintenance teams and system integrators use this actuator for valve automation upgrades, actuator replacement, preventive maintenance, and process control retrofits.

Applications:

The TRIAC Controls 2R2500DAR pneumatic actuator is commonly used in industrial process control systems including water and wastewater treatment, chemical processing, food and beverage production, pulp and paper mills, and power generation facilities where high-torque quarter-turn valve actuation is required. The reverse-acting double-acting configuration is designed for applications requiring opposite rotation from the standard actuator while maintaining ISO/NAMUR compatibility for accessories and valve mounting.
