AS Series AS2201F Pneumatic Speed Control Valve | Elbow Meter-Out Throttle Valve with One-Touch Fitting

Brand: SOLH by Richge Technology | Full Compatible Replacement for SMC AS Original Series

1. Product Overview

     The SOLH AS Series AS2201F is the most universal and widely used pneumatic cylinder speed control valve compatible with SMC standard. It adopts a built-in check valve and precision needle valve integrated structure, featuring classic one-end thread and one-end one-touch fitting design. The threaded side connects to cylinders or solenoid valves, while the quick-fit side enables tool-free fast tubing installation. With standard elbow shape, stable meter-out throttling logic and optional push-lock & pre-sealed thread, it serves as the mainstream universal throttle valve for standard pneumatic cylinder circuits in industrial automation.

3. Detailed Parameter & Code Explanation

  3.1 Body Size Code

  3.2 Structural Type Code

  3.3 Throttling Control Mode

  3.4 One-Touch Fitting (F Code)

     F represents equipped with upgraded second-generation quick connector, fully compatible with KQ2 series fittings. It supports direct plug-in installation for PU tubes and nylon tubes, realizing tool-free fast pipeline assembly and greatly improving on-site installation efficiency.

  3.5 Thread Type Code

3.6 Port Size Specification

3.7 Applicable Tubing Outer Diameter

3.8 Sealing & Surface Treatment Method

3.9 Locking Mode (Suffix A)

     A stands for push-lock type handwheel. After adjusting the pneumatic speed by rotating the handwheel, pressing down the knob can lock the adjustment position firmly. It effectively prevents speed deviation caused by equipment vibration or accidental touch, ensuring long-term stable operation of pneumatic circuits.

4. Professional Selection Rules & Formula

     • Throttling Priority: Select code 0 (meter-out exhaust throttling) for over 95% conventional working conditions for stable cylinder movement.

     • Structural Selection: Choose elbow type (code 2) for sufficient installation space; choose universal type (code 3) for narrow space or adjustable tubing direction.

     • Port & Tubing Matching: Confirm thread size according to cylinder interface, select one-touch spec based on outer diameter of pneumatic tube.

     • Sealing Selection: Choose S suffix pre-sealed type for fixed one-time installation; choose standard non-seal type for frequent disassembly and maintenance.

     • Anti-shift Configuration: Equip with A suffix push-lock structure for vibrating equipment or public shared equipment to avoid parameter drift.

One Sentence Summary

     The SOLH AS2201F series is a universal SMC-compatible pneumatic speed control valve with integrated check valve and needle valve, featuring elbow meter-out throttling, tool-free one-touch quick installation, optional pre-sealed thread and push-lock anti-vibration design, being the most cost-effective and widely applicable flow control solution for standard industrial pneumatic cylinder circuits.
