High Power Single Acting Pneumatic Piston Actuator
The pneumatic piston actuator is a single-acting device with a crank arm. Therefore, it converts the linear movement of the piston into a precise 90° rotation. Compressed air pushes the piston through the cylinder. Consequently, the crank arm transforms that displacement into a quarter turn. It is ideal for operating ball, butterfly, and segmented ball valves in ON/OFF services.
The crank arm features an integral cast construction. Furthermore, it offers high strength, good stability, and strong impact resistance. Additionally, it includes two lateral adjustment screws that allow for stroke regulation within a range of ±10°. Consequently, adjustment is quick and simple, requiring no special tools. Likewise, the aluminum body with anti-abrasion treatment guarantees durability in demanding industrial environments.

Main Applications
The pneumatic piston actuator is used in the automation of quarter-turn valves, such as ball, butterfly, and segmented ball valves. Likewise, it is used for flow control and isolation in liquid and gas process lines.
Quarter-turn valve automation The pneumatic piston actuator operates ball, butterfly, and segmented ball valves in ON/OFF services. Therefore, it is the preferred choice when high torque force is required in confined spaces.
Industrial flow control and isolation Enables automatic operation of liquid and gas process lines. Furthermore, it reduces manual intervention and improves cycle repeatability.
Chemical, petrochemical, and process plants Ensures reliable compressed air actuation in aggressive environments. Consequently, it is suitable for corrosive fluids, vapors, and high temperatures.
Water and wastewater treatment systems Operates in potable water, industrial water, and effluent treatment systems. Likewise, it supports continuous operation in humid and industrial environments.
Power generation and auxiliary services Used in compressed air, steam, thermal oils, and general service fluid applications. Therefore, it is compatible with the requirements of power plants and refineries.
Integration in skids and packaged equipment Easily integrates with solenoid valves, limit switch boxes, and positioners. Consequently, it allows for complete automation in compact process modules.
