Unox Double Acting Pneumatic Actuated Stainless Steel Flanged Ball Valve

What is a Pneumatic Actuated Stainless Steel Ball Valve?

A flanged ball valve is a type of valve used in piping or machinery systems to control the flow of water, gas, or other fluids. These valves are designed with an internal cross-axis ball mechanism, allowing fluid to pass directly through the valve when open. Thanks to this design, flanged ball valves are especially suitable for pressurized systems and can be configured to handle high flow rates or high-pressure conditions.

Flanged ball valves are typically mounted onto a system via a flange, which provides a secure and leak-proof connection between the valve and the pipeline or machinery.

Depending on the connection sizes, pneumatic actuators with torque ratings ranging from 9 Nm to 400 Nm are used. Optional accessories such as switch boxes and directional control valves can also be integrated upon request.

Actuator Codes, Torque Values, and Applications:

• UDA 040 = 9 Nm

• UDA 052 = 25 Nm

• UDA 063 = 50 Nm

• UDA 083 = 94 Nm

• UDA 092 = 135 Nm

• UDA 105 = 270 Nm

• UDA 125 = 400 Nm

Ball Valve Control Types:

• On-Off Control

• Proportional Control

Construction Features:

• Aluminum Extrusion Cylinder: The inner surface of the cylinder is precision-machined to ensure long life, resistance to internal and external corrosion, and a low coefficient of friction.

• Compact Pistons: Made from special aluminum alloy, these pistons allow for symmetric and easy installation, fast actuation, and reversible operation by repositioning.

• High-Quality Pinion: Manufactured from corrosion-resistant steel, the pinion allows mounting at 45° to 90° angles and works in sync with the piston stroke for full functionality in various mounting positions.

• Industrial Bearings: Made from high-strength plastic to minimize wear and friction, enabling rapid open-close cycles with low resistance.

• Precision Gearing: Gear teeth between piston and pinion are precisely machined to ensure silent, efficient, and high-performance operation.

• Corrosion-Resistant Fasteners: All connecting components are made of stainless steel for long-term durability.

• Compliance with Latest Standards: All components comply with ISO 5211, DIN 3337, and VDI/VDE 3845 (NAMUR) standards. Accessories like solenoid valves, limit switches, and other components can be easily mounted or replaced, ensuring high compatibility and modularity.
