Smc Pneumatics AS4301F-N04-13 Flow Control Valve

Product Description

The SMC PNEUMATICS AS4301F-N04-13 is an inline offset flow control valve designed to regulate airflow and control actuator speed in pneumatic systems. This valve accepts a 1/2 inch tube outside diameter and connects via a 1/2 inch NPT male thread, making it suitable for standard compressed-air plumbing configurations. It provides metered flow adjustment in a compact inline body, allowing technicians to fine-tune cylinder speed or downstream pressure without additional fittings. Licensed pneumatic and mechanical technicians install this type of valve during system commissioning or as a replacement in existing pneumatic circuits.

The AS4301F-N04-13 is used in industrial and commercial pneumatic systems where precise flow and speed control is required. Typical applications include actuator speed regulation on assembly lines, packaging equipment, and automated machinery. The offset inline body style accommodates installations where straight-through plumbing is not practical. This valve suits both new pneumatic circuit builds and retrofit applications that require a reliable, adjustable flow control point.

Key Features

• Inline offset body style for flexible routing in tight plumbing layouts
• 1/2 inch tube outside diameter for direct push-to-connect or compression fitting compatibility
• 1/2 inch NPT male thread for connection to standard pipe fittings and manifolds
• Combines flow control and speed control functions in a single valve body
• Adjustable metering for precise actuator speed tuning

Compatibility

Designed as an OEM-style replacement or new-installation flow control valve for pneumatic systems using 1/2 inch OD tubing and 1/2 inch NPT male threaded ports.

Installation Notes

Installation is typically performed by a licensed pneumatic or mechanical technician. Depressurize and lock out the compressed-air supply before removing or installing any flow control valve. Apply thread sealant to NPT threads in accordance with the system manufacturer guidelines and applicable industry standards. Do not over-tighten the NPT connection, as this can crack the valve body or distort the thread seal.
