Product Overview
The SMC AS500 is a precision pneumatic speed controller (flow control valve) engineered by SMC Corporation, a global leader in pneumatic and industrial automation technology. Operating on a unidirectional flow control principle, the AS500 combines a needle valve for precise flow regulation with an integrated check valve that permits free reverse flow. This configuration allows engineers to independently control actuator extension or retraction speed while maintaining unrestricted return flow, making it an essential component in pneumatic motion control circuits. The AS500 is designed for inline or elbow mounting directly onto pneumatic cylinders and actuators, delivering stable, repeatable speed regulation across demanding industrial duty cycles.

Engineering Features & Advantages
- Precision Flow Metering: The fine-thread needle valve enables sensitive, stepless adjustment of air flow, allowing accurate and repeatable control of pneumatic actuator stroke speed.
- Integrated Check Valve: Permits unrestricted free flow in the reverse direction, ensuring rapid actuator return without compromising controlled movement in the metered direction.
- Compact & Robust Construction: Lightweight yet durable body designed for direct mounting on cylinders and valves, minimizing installation space and piping complexity.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with stable performance across wide pressure and temperature ranges.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original SMC AS Series specifications for drop-in service replacement.
Typical Industrial Applications
The SMC AS500 pneumatic speed controller is widely deployed in automated manufacturing and process environments, including pneumatic cylinder speed regulation on packaging and assembly machinery, controlled actuation in plastic injection molding and blow molding equipment, motion sequencing in CNC machine tool automation and pick-and-place systems, and general pneumatic circuit speed control across metallurgical, automotive, and material handling operations where precise, repeatable actuator timing is critical.
