Tork-Mate 890-250 DA Pneumatic Actuator

Description:

The Tork-Mate 890-250 DA pneumatic actuator is used in industrial valve automation systems to provide double-acting rotary motion for 90-degree quarter-turn devices. Commonly installed on butterfly valves, ball valves, plug valves, damper valves, and other industrial flow-control equipment. Maintenance teams and system integrators use this part for pneumatic actuator replacement, automated valve repair, process system retrofit, and restoration of reliable valve operation.

Applications:

The Tork-Mate 890-250 DA pneumatic actuator is commonly used in industrial process systems, material handling equipment, pneumatic conveying systems, and automated valve assemblies where a double-acting rack-and-pinion actuator is required to operate quarter-turn valves and dampers.
