Smc Pneumatics AS4201F-N04-13 Flow Control Elbow Valve

Product Description

The SMC PNEUMATICS AS4201F-N04-13 is a flow control elbow valve designed to regulate airflow in pneumatic systems. It uses a tube-to-male NPT connection with a 1/2-inch tube outside diameter and a 1/2-inch male thread, making it a compact inline solution for controlling actuator speed and cylinder motion. The body is constructed from polybutylene terephthalate, a durable thermoplastic suited for pneumatic service. This valve controls outflow, meaning it meters air exiting the actuator to achieve smooth, consistent motion. It is installed by pneumatic system technicians and maintenance professionals in industrial and automation environments.

This valve is suited for use in compressed air circuits where precise speed control of pneumatic actuators is required. The elbow configuration allows routing changes at the connection point, reducing the need for additional fittings in tight spaces. It is appropriate for both light industrial and general-purpose automation applications. The operating temperature range spans -5 degrees C to 60 degrees C, making it suitable for standard indoor industrial conditions. Typical applications include pneumatic cylinder speed control, directional control circuit tuning, and flow restriction in automated machinery.

Key Features

• Outflow speed control meters air exiting the actuator for smooth cylinder movement
• Elbow body configuration allows 90-degree routing at the connection point
• Polybutylene terephthalate body offers resistance to wear and chemical exposure in pneumatic service
• Tube x MNPT connection accepts 1/2-inch OD tubing with a 1/2-inch male NPT thread
• Rated for operating temperatures from -5 degrees C to 60 degrees C

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic flow and speed control circuits using 1/2-inch OD tube and 1/2-inch NPT threaded ports.

Installation Notes

Installation should be performed by a qualified pneumatic technician. Depressurize the air supply and bleed residual pressure from the circuit before removing or installing any flow control valve. Ensure tubing is cut cleanly and squarely before inserting into the push-to-connect fitting to achieve a proper seal. Thread engagement should follow standard NPT assembly practices with appropriate thread sealant applied to male threads.
