The Pneumatic Actuated Butterfly Valve with Split Gear Arm is one of the control valves designed for large-diameter fluid lines, operating with high torque and capable of integration into automation systems. These valves regulate the flow of fluids such as gas, water, or air using a rotating disc mechanism. Developed by Unox, this model is particularly preferred in plants that require precise flow management in large pipelines. However, if the actuator torque is not properly selected for the application, the system will not operate efficiently. The Unox Electric Actuated Flanged Ball Valve is another product commonly chosen for similar applications.

Wide Range of Applications with High Torque Capacity

In this product group, actuator torques range from 9 Nm to 400 Nm. For example, the UDA 040 model provides 9 Nm of torque, while the UDA 125 model reaches up to 400 Nm. However, not only torque but also the valve diameter and operating pressure must be taken into account. The Unox Multi-Turn Proportional Electric Actuated Valve is used in similar systems. In addition, both on-off and proportional control options allow configuration according to system requirements.

Mechanical Design and Material Quality

The valve body is manufactured using aluminum extrusion and is resistant to corrosion. Compact pistons provide rapid response thanks to their special alloy construction. The pinion is made of high-quality steel and is mounted at angles between 45° and 90°, allowing easy adaptation to different installation scenarios. In addition, integrated solutions are offered in combination with products such as the Electric Actuated 2-Piece Gear Ball Valve.

Wear Resistance and Quiet Operation Performance

The bearing components are made of hard plastic, reducing friction and ensuring quiet operation. This design also lowers the system’s wear rate. The module teeth of the piston and pinion are specially processed for high-efficiency performance. It enhances system performance by operating compatibly with products such as the Unox Electric Actuated 3-Way Ball Valve.

Ease of Installation and Compliance with Standards

The system fully complies with ISO 5211, DIN 3337, and VDI/VDE 3845 NAMUR standards. This allows accessories such as solenoid valves, switch boxes, and limit switches to be easily added. Technical drawings and compatible product components can be accessed online via Unox. Lightweight systems can be created in combination with the Unox Electric Actuated U-PVC Ball Valve.
