Smc Pneumatics AS3201F-N03-11 Air Flow Control Valve

Product Description

The SMC PNEUMATICS AS3201F-N03-11 is a pneumatic flow and speed control valve designed to regulate airflow in compressed-air systems. It uses a tube-to-male NPT connection with a 3/8-inch tube outside diameter and a 3/8-inch male NPT thread. The valve is configured for outflow control, meaning it meters air exiting the actuator to manage cylinder or actuator speed. The body is molded from polybutylene terephthalate (PBT), a glass-reinforced thermoplastic suited for pneumatic service. Licensed HVAC technicians, industrial maintenance technicians, and automation specialists typically install this type of valve in pneumatic control circuits.

This valve is suited for use in compressed-air pneumatic circuits found in industrial automation, process equipment, and HVAC pneumatic actuator systems. It is installed inline between a directional control valve and a pneumatic cylinder or actuator to provide adjustable speed control on the exhaust stroke. The operating temperature range of -5 degrees C to 60 degrees C makes it appropriate for standard indoor industrial and light commercial environments. It is a single-unit supply item with a minimum order quantity of one.

Key Features

• Outflow (meter-out) configuration for actuator speed control on the exhaust stroke
• Tube x MNPT connection accepts 3/8-inch OD tubing on one end and a 3/8-inch male NPT fitting on the other
• PBT body construction provides chemical resistance and dimensional stability under pneumatic service conditions
• Operating temperature range: -5 degrees C to 60 degrees C
• NPT thread type for compatibility with standard North American pipe fittings

Compatibility

Designed as an OEM-style replacement or direct-install flow control valve for pneumatic circuits using 3/8-inch OD tubing and 3/8-inch NPT ported components. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified pneumatic or industrial maintenance technician. Depressurize the compressed-air circuit completely before removing or installing any valve components. Ensure NPT threads are sealed with an appropriate thread sealant compatible with compressed air service. Verify tubing OD and NPT port size against system requirements before installation to avoid misfit connections.
