ASN2 Series Exhaust Throttle Valve with Silencer | Integrated Speed Control & Noise Reduction Valve

Brand: SOLH by Richge Technology | SMC Compatible Integrated Pneumatic Throttle Silencer Valve

1. Product Overview

     The SOLH ASN2 series is an all-in-one exhaust throttle valve with built-in silencer, specially designed for direct mounting on the EXH exhaust port of pneumatic solenoid valves. It integrates exhaust speed regulation and noise reduction functions in one unit, eliminating the need for separate silencer installation. Adopting precision needle valve throttling structure and anti-drop adjustment design, the upgraded resin-type ASN2-A features lightweight body, precise scale adjustment and push-down locking function. It is a cost-effective, space-saving and high-stability exhaust speed control solution for standard pneumatic solenoid valve circuits.

2. Core Working Functions & Advantages

     • Special Solenoid EXH Port Installation: Different from cylinder-end throttle valves, ASN2 is exclusively installed on solenoid valve exhaust ports for professional outlet throttling speed regulation, optimizing overall pneumatic circuit layout.

     • Precision Exhaust Throttling Logic: Standard outlet throttling control; clockwise rotation reduces airflow for slower cylinder movement, counterclockwise rotation increases airflow for faster action, realizing stepless speed adjustment.

     • High-Efficiency Integrated Silencer: Built-in high-performance noise reduction structure, achieving over 20dB noise reduction even under maximum flow conditions, effectively solving pneumatic exhaust noise pollution.

     • Needle Valve Anti-Drop Structure: The adjustment knob adopts anti-loosening and anti-drop design, preventing knob falling off and parameter deviation caused by long-term equipment vibration, ensuring stable long-term operation.

3. Model Coding Rules & Specification Definition

     Typical Model Example: ASN2-02A

     • ASN2: Series code for integrated exhaust throttle valve with silencer

     • Caliber Code: M5 (M5×0.8) / U10 / 32 / 01(R1/8) / 02(R1/4) / 03(R3/8) / 04(R1/2)

     • A Suffix: Upgraded lightweight resin type, equipped with push-down locking structure and precision scale window

6. Upgraded Features of ASN2-A Resin Type

     • Ultra-Lightweight Design: Adopts high-strength resin material, weight reduced by about 80% compared with traditional metal main body, minimizing load on solenoid valve exhaust port.

     • Precision Scale Window: Equipped with vernier scale indicator, supporting 1/4 circle micro adjustment. The flow parameter is visible and quantifiable, realizing standardized and repeatable flow management.

     • Convenient Push-Down Locking: Innovative push-down knob locking structure. After speed adjustment, pressing the knob can lock the parameter position, effectively preventing speed drift caused by equipment vibration and ensuring consistent operation accuracy.

7. Model Selection Distinction: ASN2 vs AS / ASV / ASC Series

8. Installation Guidelines & Precautions

     • Standard Installation Method: Directly screw the valve onto the solenoid valve EXH exhaust port with the valve body facing outward, reserving sufficient operating space for daily speed adjustment.

     • Applicable Circuit Restrictions: Not applicable to circuits with middle position check valves and pilot-operated one-way valves, which may cause abnormal cylinder action and unstable operation.

     • Vibration-Proof Locking Operation: After completing airflow and speed debugging, lock the adjustment knob to avoid running speed deviation caused by long-term equipment vibration.

One Sentence Summary

     The SOLH ASN2 series is an integrated exhaust throttle and silencer valve dedicated to solenoid valve exhaust ports. Featuring noise reduction, precise adjustable speed, anti-drop vibration-proof structure and lightweight resin upgrade option, it simplifies pneumatic circuit installation, reduces exhaust noise, and is the optimal economical speed control and noise reduction accessory for standard pneumatic solenoid systems.
