Smc Pneumatics ASN2-N03 Metering Valve with Silencer

Product Description

The SMC PNEUMATICS ASN2-N03 is a brass metering valve with an integrated silencer designed to regulate and exhaust airflow in pneumatic systems. It combines flow control and noise attenuation in a single compact fitting, reducing the need for separate silencer components. The valve uses a 3/8 inch NPT male thread connection and features an outlet size of 16.60 mm. It is rated for operating temperatures from -5 degrees C to 60 degrees C. Pneumatic technicians and automation system installers use this component to tune actuator speed and manage exhaust noise at control valves, cylinders, and directional control valve banks.

This valve is suited for use in industrial pneumatic circuits where exhaust flow needs to be metered and dampened simultaneously. Typical applications include controlling the extend or retract speed of pneumatic cylinders and reducing exhaust noise at directional valve ports in both light industrial and production automation environments. The 3/8 inch NPTM connection makes it a straightforward fit into standard NPT-threaded valve manifolds and cylinder port blocks.

Key Features

• Integrated silencer eliminates the need for a separate exhaust muffler
• Brass body construction for durability in industrial pneumatic service
• 3/8 inch NPT male thread for standard North American pneumatic plumbing
• Metering function allows precise exhaust flow adjustment for actuator speed control
• Operating temperature range of -5 degrees C to 60 degrees C suits most indoor industrial environments
• Outlet size of 16.60 mm supports adequate exhaust volume for typical cylinder applications

Compatibility

Designed as an OEM-style replacement or direct-fit component for pneumatic systems using 3/8 inch NPTM exhaust or flow-control ports. Consult the system schematic and valve manifold port specifications to confirm fitment before installation.

Installation Notes

Installation is performed by qualified pneumatic technicians or automation maintenance personnel. Depressurize and lock out the pneumatic circuit completely before removing or installing any flow control valve. Apply thread sealant rated for compressed air service to the NPT threads; do not overtighten brass fittings in aluminum or cast-iron ports. After installation, gradually restore system pressure and adjust the metering needle to achieve the desired actuator speed before securing the lock nut.
