Description
1. Overview of Electric Control Valve
The electric control valve from VTON integrates advanced electric actuators with durable valve bodies to achieve high-precision regulation of fluid parameters. These valves are powered by AC 220V and controlled using 4-20mA or 0-10mA signals, enabling seamless automation in industrial systems.
Key Features:
- Sensitive and precise control for continuous adjustment of pressure, flow, and liquid levels.
- Easy integration into automation systems with rapid response and reliable performance.
- Suitable for various operating conditions, including high and low temperatures, with optional configurations.
