Smc Pneumatics AS2301F-N01-09 Flow Control Valve

Product Description

The SMC PNEUMATICS AS2301F-N01-09 is an offset inline flow control valve designed to regulate airflow speed in pneumatic systems. It connects via a push-to-connect tube fitting on one end and a 1/8 inch male NPT thread on the other, accommodating a tube outside diameter of 5/16 inches. The valve controls outflow, allowing precise adjustment of actuator speed during the exhaust stroke. The body is constructed from polybutylene terephthalate (PBT), a durable thermoplastic suited for pneumatic plumbing environments. This valve is installed by pneumatic technicians and automation maintenance personnel in both industrial and light manufacturing settings.

This valve is applied in pneumatic circuits where speed control of cylinders, actuators, or other pneumatic devices is required. The offset inline design allows installation in space-constrained tubing runs without requiring a straight-line alignment. It is suited for use in assembly line equipment, material handling systems, and machine automation panels where precise exhaust flow control contributes to repeatable cycle timing. The NPT male thread allows direct mounting into standard ported blocks, manifolds, or pneumatic fittings.

Key Features

• Offset inline configuration for installation in tight or angled tubing layouts
• Tube outside diameter of 5/16 inches with push-to-connect interface
• 1/8 inch male NPT thread for standard ported mounting
• PBT body material offers resistance to oils and common pneumatic system fluids
• Outflow speed control for cylinder exhaust regulation
• Operating temperature range of -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 5/16 inch OD tubing and 1/8 inch NPT ported connections.

Installation Notes

Installation should be performed by a qualified pneumatic technician. Depressurize the pneumatic circuit fully before removing or installing any flow control components. Ensure the male NPT threads are wrapped with thread sealant tape appropriate for pneumatic service before installation. Do not overtighten the threaded connection into the port, as PBT fittings can crack under excessive torque.
