ITV Series High Flow Electro-Pneumatic Proportional Valve

Brand: SOLH by Richge Technology 

Product Positioning & Working Principle

   1. Product Positioning

     SOLH ITV series high flow electro-pneumatic proportional valve is an SMC-interchangeable electric-to-pneumatic conversion component. It realizes stepless continuous air pressure adjustment via electrical control signals, fully replacing manual pressure reducing valves to achieve automatic, high-precision remote pressure regulation, and is specially optimized for heavy-duty large-flow air supply circuits.

   2. Core Function & Principle

     -- Core Function: Convert electric control signal to stepless adjustable air pressure for automatic & remote pressure regulation

     -- Working Principle: Closed-loop electro-pneumatic proportional feedback system. Built-in pressure sensor monitors output pressure in real time and automatically corrects deviation, delivering outstanding control accuracy and fast response speed

     -- Environmental Protection Grade: IP65 dustproof & splash-proof, stable operation in harsh industrial workshop conditions

     -- Built-in high-brightness LED digital display for real-time pressure value visualization; equipped with self-diagnosis algorithm and fault alarm output to simplify on-site troubleshooting & maintenance.

Typical Industrial Application Scenarios

     -- Pressure control for large-flow cylinders & pneumatic actuators: Packaging machines, automatic dispensing & gluing equipment

     -- Multi-stage automatic pressure switching: Welding equipment, riveting stations, film & wire tension control systems

     -- Ultra-precision pneumatic process loops: Semiconductor manufacturing, optical testing, medical precision automation equipment

     -- Centralized remote pressure adjustment on automated production lines: Replace multiple sets of manual regulators for one-stop digital pressure control

Model Selection Guidelines

     -- Select series by required flow rate: ITV1100 for micro small flow, ITV2100 for universal medium flow, ITV3100 for high-flow heavy-duty equipment

     -- Confirm adjustable pressure range to fully cover all process working pressure requirements (0.005–0.9 MPa full range optional)

     -- Match control signal type: DC0–10V analog voltage as standard choice; select dedicated communication board if fieldbus digital control is needed

     -- Confirm mounting form: Base mount / side mount / bracket mount to match on-site air pipeline layout
