ASV Series Quick Exhaust Throttle Valve | 4-in-1 High-Speed Pneumatic Speed Control Valve with Silencer & One-Touch Fitting

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

1. Product Overview

     The SOLH ASV series is a 4-in-1 integrated high-speed pneumatic control valve that combines quick exhaust function, exhaust throttling regulation, built-in silencer and one-touch fitting. Different from conventional single-function speed control valves, the ASV series features double effective flow area, enabling fast cylinder extension and adjustable silent retraction. It perfectly solves the contradiction between high-speed cylinder action and stable speed regulation, serving as the core preferred valve for high-frequency, high-speed and low-noise pneumatic automation scenarios, fully interchangeable with original SMC ASV series.

2. Core Working Principle & Functions

     • Intake Stroke (IN → OUT / Cylinder Extension): The internal check valve fully opens with zero flow resistance, realizing large-flow straight-through air intake. It greatly improves cylinder extension speed and meets high-speed rapid action requirements.

     • Exhaust Stroke (OUT → EXH / Cylinder Retraction): The check valve closes automatically. The exhaust air passes through precision needle valve throttling for stepless speed adjustment, while the built-in silencer eliminates exhaust noise. It achieves adjustable retraction speed and silent operation.

     • Superior High-Flow Performance: The effective sectional flow area is about 2 times that of ordinary AS series speed control valves, providing powerful flow support for high-speed cylinder movement and high-frequency cyclic operation.

3. Model Coding Rules & Parameter Definition

  Typical Model Example: ASV310F-01-06A

     • ASV: Series code for 4-in-1 quick exhaust throttle valve with silencer and one-touch fitting

     • Size Code (120/220/310/410/510): Corresponding to M3/M5/G1/8/G1/4/G3/8 port specifications

     • F: Equipped with one-touch quick connector for fast tubing installation

     • Thread Code (01/02/03/04): 01=R1/8, 02=R1/4, 03=R3/8, 04=R1/2

     • Tube Outer Diameter Code: Adaptable to φ4/φ6/φ8/φ10/φ12 pneumatic tubes

     • Suffix Definition: A=push-lock handwheel; S=thread pre-coated sealant; N=electroless nickel plating

4. Two Structural Types & Application Characteristics

  4.1 Elbow Type (ASV120F / ASV220F)

     • 90° elbow steering structure, same appearance as AS series elbow speed control valve, compact and space-saving.

     • Asymmetric interface design: one side M3/M5 thread port, the other side one-touch quick-fit port.

     • Ideal for miniature & small cylinders and narrow-space equipment layout scenarios.

  4.2 T-Type Straight Through (ASV310F / 410F / 510F)

     • Three-port straight-through structure: IN thread air inlet, OUT quick-fit air outlet, EXH built-in silent exhaust port.

     • Larger effective flow area and lower flow resistance, maximizing cylinder operating speed.

     • The preferred structure for standard, medium and large bore high-speed cylinders.

8. Professional Installation & Operation Guidelines

     • Directional Installation: Install strictly according to the arrow mark on the valve body. Connect the IN port to the solenoid valve and the OUT port to the cylinder to avoid reverse installation causing abnormal speed regulation.

     • Quick Tubing Connection: Cut the pneumatic tube flat and insert it fully into the one-touch fitting until a "click" sound is heard, confirming firm and airtight connection.

     • Vibration-Proof Locking Operation: Rotate the handwheel to adjust exhaust flow and cylinder speed. Press down the handwheel to lock and prevent speed drift caused by equipment vibration;pull up the handwheel to unlock for secondary adjustment.

One Sentence Summary

     The SOLH ASV series is a professional 4-in-1 high-speed pneumatic control valve integrating quick exhaust, exhaust throttling, silent noise reduction and one-touch fitting. With double flow area, push-lock anti-vibration structure and fireproof durable material, it perfectly meets high-speed, high-frequency and silent operation demands of pneumatic cylinders, being the optimal upgrade replacement for ordinary AS series speed control valves.
