AS Series Pneumatic Flow Control Valves and Speed Controllers

AS Series: Product and Selection Guide

Meter-out and Meter-in Flow Control

For the illustrated meter-out type, the knob adjusts the exhaust flow. Reverse flow is not throttled by that adjustment. Match the flow-control direction to the pneumatic circuit.

Model Code Guide

Example: AS1201F-01-06SA

• Body-size code and elbow-style designation identify the construction.
• Control code: 0 = meter-out; 1 = meter-in.
• Thread codes shown in the selection guide: M3, M5, 01 = PT 1/8, 02 = PT 1/4, 03 = PT 3/8, 04 = PT 1/2.
• Tube outside-diameter codes: 04 = 4 mm, 06 = 6 mm, 08 = 8 mm, 10 = 10 mm, 12 = 12 mm, 16 = 16 mm.
• S denotes thread sealant in the illustrated model code; A denotes the push-lock design.

This example explains the illustrated elbow family, not every specialty or in-line model offered on this page. Select only the exact model needed.

Reference Drawing and Dimension Tables

Thread-standard notice: The source labels the following drawing and tables as NPT-thread reference material, while the selection guide above lists PT connections. NPT and PT must not be treated as interchangeable. These reference tables are not confirmed specifications for every sale variant; verify the selected model and thread before ordering.

The square in the table model codes is a source wildcard, not a missing digit to be guessed. The supplied source references Notes 1 and 2 but does not include their explanations; no interpretation of those notes or parenthesized values is assumed. Confirm critical dimensions before installation.
