Description
1. Overview of Self-Operated Pressure Regulating Valve
Self-operated pressure regulating valves, also known as self-operated control valves or spring-loaded regulating valves, operate using the medium’s own pressure, pressure difference, or temperature as the energy source. These valves automatically adjust pressure, flow, or temperature without requiring external power or secondary instruments.
Key Features:
- Energy-efficient and eco-friendly, requiring no external power supply.
- Separate sealing for signal and drive components, eliminating leaks caused by internal part wear.
- Combines signal detection, amplification, feedback, control, and execution within a single unit, ensuring reliability with simple yet effective design.
- Easy installation, low cost, and suitable for environments with high pipe density or humidity where other systems may require electricity or compressed air.
