SMC ASV310F-01-06S Speed Exhaust Controller

ASV310F-01-06S

1. ASV: Series Code → Speed Exhaust Controller (Integrated speed control + quick exhaust function)
2. 310F: Size Series

310: Valve body dimension; F = Integrated quick exhaust function (Standard ASV without F has no quick exhaust)

3. 01: Thread Port → Rc1/8 (Female Thread)
4. 06: Tube Outer Diameter → φ6mm PU Air Tubing
5. S: One-way throttling direction identifier

Specification S: Free flow for air supply, throttling for exhaust; Throttling + quick exhaust fitted on cylinder exhaust port to improve cylinder retraction speed

2. Spécifications de base

3. Principe de fonctionnement

ASV-F integrates check valve + throttle valve + quick exhaust valve

Cylinder extend: Compressed air flows into the valve body, the check valve opens, airflow bypasses throttling, full-speed extension.

Cylinder retraction: Internal cylinder air discharges outwards, the check valve closes; air can only pass through the throttle knob for speed regulation. Entre-temps, the built-in quick exhaust channel discharges directly to atmosphere, reducing the influence of piping volume and greatly improving response speed during cylinder retraction.

4. Piping & Connection Instructions
5. Mount the valve body with Rc1/8 internal thread directly onto cylinder port
6. Connect Φ6 tubing to one-touch port (Push-fit for quick assembly & disassembly)
7. Adjustment knob: Clockwise → Reduce flow, lower speed; Counterclockwise → Increase flow
8. Tighten lock nut after adjustment to prevent drift caused by vibration
9. Scénarios d'application typiques

Retraction speed boost for compact cylinders (CDQ2B, CJ2A, MB series)

Manipulators, tooling fixtures, pushing mechanisms requiring fast return and controllable forward speed

Short-stroke cylinders, eliminate exhaust lag caused by long piping

6. Guide de sélection & Informations de remplacement
7. Distinguish Type S / UN

ASVxxx-xx-xxS: Exhaust throttling (Le plus courant, standard cylinder speed control)

ASVxxx-xx-xxA: Inlet throttling, rarely used – avoid wrong selection

2. Similar models within the same series

ASV310F-01-04S: RC1/8, Φ4 tubing

ASV310F-02-06S: RC1/4, Φ6 tubing

3. Standard ASV310 (without F) cannot be directly replaced; no built-in quick exhaust, obvious difference in retraction speed
4. Dépannage courant
5. Slow cylinder movement: Throttle knob closed too far; tubing flattened; joint leakage
6. Invalid speed regulation, unstable speed: Loose lock nut leading to knob rotation; foreign particles jamming internal check valve
7. Air leakage: Tubing not fully inserted; insufficient PTFE tape on thread; worn internal valve seals

2. Key Abstract from English & Chinese Catalog

Chinese Specification

Nom du produit: Speed Exhaust Controller with Built-in Silencer

Modèle: ASV310F-01-06S

1. Support de travail: Air comprimé (Oiled / Oil-free)
2. Pression de preuve: 1.5 MPa
3. Plage de pression de fonctionnement: 0.1～1.0 MPa
4. Ambiant & Température du fluide: -5℃～60℃ (No icing allowed)
5. Matériau du corps: Flame-retardant resin UL94 V-0; Metal parts with electroless nickel plating
6. Flow Definition (Type S Exhaust Throttling)

Inlet (Thread → Tubing): Check valve fully open, unrestricted airflow

Exhaust (Tubing → Atmosphere): Air passes through adjustable needle valve, built-in quick exhaust channel + silencer for direct atmospheric discharge

7. Effective Flow Area: Roughly doubled compared to standard AS speed controller, significantly improved cylinder retraction speed
8. Compatible Tubing: Polyurethane PU, nylon doux, hard nylon tubing
9. Caractéristiques du débit (Key for Selection)
10. IN→OUT (Air Supply): Large flow area, negligible pressure drop, cylinder extends at full speed
11. OUT→EXH (Exhaust): Adjustable throttling with simultaneous quick exhaust
12. Convient pour: Short-stroke cylinders, applications requiring fast retraction response, no need for separate external quick exhaust valve.

⚠️ Comparison with standard ASV310 (without F): No built-in quick exhaust, severe exhaust lag in long piping, non-interchangeable.

4. Replacement Model List

1) Direct SMC OEM Replacement (Identical function)

ASV310F-N01-06S: Thread changed to NPT1/8 (American thread; confirm thread standard before installation)

❗ Mismatched thread prevents direct mounting; Rc1/8 preferred for domestic standard

2) Domestic Compatible Alternatives (Consistent structure, dimension & flow direction)

Note: Many domestic manufacturers distinguish Type A/S; confirm suffix S = exhaust throttling. Low-cost variants may not meet UL-V0 flame resistance; avoid for welding environments.

3) Airtac Alternative Solution

Airtac does not manufacture integrated speed exhaust controllers with identical form factor. Alternative combination: PSL601 (Exhaust Speed Controller) + QE01 Quick Exhaust Valve. Larger overall installation footprint.

5. Installation, Commissioning Specifications & Opérations interdites

Étapes d'installation

1. Wrap PTFE tape on external thread only (Do not block internal flow passage)
2. Tightening torque for Rc1/8 thread: 2.5～3.5 N·m. Excessive torque cracks resin valve body
3. Vertically insert Φ6 tubing into fitting until audible “cliquez” confirms locking
4. Adjustment: Counterclockwise → Larger flow; Clockwise → Smaller flow
5. Lock side nut after speed setting to avoid vibration drift

⚠️ Strictly Forbidden Operations

1. Prohibited for vacuum circuits; Medium limited to compressed air only
2. Operating pressure shall never exceed 1.0 MPa
3. Do not block built-in exhaust silencer port; Blockage disables quick exhaust and causes cylinder stalling
4. Avoid sharp bending of fitting root, which leads to air leakage
5. Optional splash guard recommended for heavy dust environments (ASV310F optional accessory)
