SMC Speed Control Valve 1/8 in NPT

The SMC AS2201F-N01-07S is a meter-out speed control valve designed for pneumatic flow regulation. It features a brass and PBT body with nickel-plated finish and an elbow-style fitting. The valve uses a screw adjustment mechanism for precise air flow control in automated systems.

Installers needing meter-out flow control

This valve suits pneumatic circuits requiring controlled exhaust flow from actuators. The 1/8 inch NPT connection fits standard compressed air ports. Buyers needing meter-in regulation or a different port thread should look at alternative valve types.

Maximum operating pressure 145 psi

The valve operates between 14.5 psi and 145 psi with a maximum flow rate of 6.4 cfm. It handles temperatures up to 140 degrees Fahrenheit. Verify your system pressure and flow requirements match these limits before installation.

Questions about this item

How do I install the AS2201F-N01-07S speed control valve and which thread sealant step is often missed?

Connect the 1/8 in NPT male threads into the port using PTFE tape on the tapered threads; the elbow fitting then accepts 1/4 in tubing for the meter-out flow path.

What maintenance will the AS2201F-N01-07S require over time?

Periodically check the brass/PBT body and nickel-plated finish for corrosion or debris; clean the adjustment screw threads if actuation becomes stiff and verify the 14.5 to 145 psi pressure range remains within system limits.

What is the first performance limit reached during continuous operation of the AS2201F-N01-07S?

The 6.4 cfm maximum flow rate at 145 psi is the primary limit; sustained demand above this value will cause pressure drop across the valve before the 140 °F temperature ceiling becomes a factor.
