Critical Technical Advantages
-
Superior Reliability via Simplicity: The rotary vane design is inherently simple, utilizing a single moving vane within a pressure chamber to convert pneumatic energy directly into rotary torque. This reduction in mechanical complexity leads to high reliability and a lower total cost of ownership over the life of the actuator.
-
Wide Torque Coverage: The 1068 series features a large range of casing sizes, allowing it to produce the specific torque required for everything from small butterfly valves to large-scale rotary isolation valves.
-
Dual Configuration Versatility: Whether your process requires the fail-safe security of a spring-return model or the high-stiffness positioning of a double-acting unit, the 1068 architecture supports both modes without compromising performance.
-
Compact Power-to-Size Ratio: Because the vane acts directly on the drive shaft within the casing, the 1068 provides a high torque output in a relatively compact footprint, making it ideal for skid-mounted equipment or tight piping manifolds.
-
Precise Quarter-Turn Operation: Engineered specifically for 90-degree rotation, the 1068 provides smooth, consistent motion throughout the stroke, ensuring repeatable valve positioning and accurate flow control.
-
Ease of Mounting: The actuator is designed to be easily mounted to various rotary shaft valves, facilitating straightforward integration during new builds or retrofitting projects in existing facilities.
