SMC Series AS Speed Controller, 1/2 inches Inlet Connection size, 10mm Outlet Connection size - AS4301F-04-10S


This speed controller regulates airflow in pneumatic systems to control actuator speed and motion. It is designed for industrial compressed-air applications where flow adjustment and consistent performance are required, and is intended for use within specified pressure and temperature ranges.

Features & Benefits


• Brass body with electroless nickel plating provides corrosion resistance
• 1/2 inches G inlet thread allows straightforward panel or tubing connection
• 10mm outlet supports Compact hose or fitting integration
• Operates across 0.1–1 MPa to cover low- to medium-pressure systems
• Withstands temperatures down to -5°C and up to 60°C for varied environments
• Proof pressure 1.5 MPa ensures durability under pressure surges

**Applications**


• Suitable for controlling cylinder speed in automation lines
• Ideal for regulating flow to pneumatic actuators in manufacturing
• Used with air-driven tools requiring adjustable exhaust flow
• Can be used for laboratory pneumatic test rigs needing repeatable control
• Suitable for retrofit in electrical panel pneumatic subsystems

What material ensures chemical and wear resistance in this device?


The valve body is brass plated with electroless nickel, giving a hard, corrosion-resistant surface suited to typical industrial atmospheres.

How should inlet and outlet connections be matched to tubing?


Use a 1/2 inches G threaded connection at the inlet and 10mm-compatible fittings or tubing at the outlet to maintain proper sealing and flow.

What pressure behaviour can users expect under normal operation?


The unit functions from 0.1 MPa up to 1 MPa and is designed to tolerate temporary overpressure up to 1.5 MPa without structural failure.

Are there environmental temperature limits for installation locations?


Install where ambient and media temperatures remain within -5°C to 60°C to preserve material properties and performance.
