Ưu điểm kỹ thuật quan trọng
-
Compact Yokeless Design: The standout feature of the 480 series is its yokeless construction. This allows for a low-profile assembly that can be close-coupled to the control device. Whether utilizing a bracket or direct-mounting on a bonnet flange, this design significantly reduces the overall footprint and weight of the valve/actuator assembly.
-
Versatile Power and Speed: The 480 series is available in an extensive assortment of sizes, thrusts, and travels. This modularity allows engineers to select specific stroking speeds and power outputs to handle virtually any industrial control requirement, from rapid-response dampers to high-torque ball valves.
-
Robust Pressure Range: Designed to work with standard plant air systems, the 480 cylinder is rated for supply pressures as low as 2.4 bar (35 psig) and as high as 10.3 bar (150 psig). This wide operating window ensures reliable performance even in facilities with fluctuating air supply.
-
Extended Travel Capabilities: For equipment requiring significant linear movement to actuate, the 480 series offers maximum rated travels of up to 206 mm (8.125 inches). This long-stroke capability makes it highly effective for large-scale louver and damper systems.
-
Field-Reversible Action: Flexibility is built directly into the hardware. The positioner/actuator action can be easily reversed in the field without the need for additional parts. While the sensitivity and travel span are factory-calibrated, they can be adjusted onsite to meet changing process conditions.
-
Double-Acting Precision: These actuators utilize pneumatic pressure loading from double-acting positioners. This ensures “stiff” and accurate positioning, resisting the dynamic forces of the process media to maintain the desired setpoint with minimal deviation
