Product Features

1.Ready-to-Install & Use​:  Pressure calibration is completed at the factory, eliminating the need for on-site adjustment with professional tools or technicians. This shortens the installation cycle and lowers the user threshold—especially suitable for small and medium-sized enterprises with limited technical personnel.​

2. High Pressure Stability & Precision​:  Calibrated via professional equipment at the factory, the pressure error is minimized (usually within ±2%), outperforming the precision of on-site manual adjustment. It is ideal for scenarios requiring high pressure stability, such as precision industrial water supply and fire sprinkler systems.​

3. Anti-Misoperation Design​:  No on-site adjustment components (e.g., adjustment knobs, dials) are included, preventing pressure abnormalities caused by misoperation by non-professionals and reducing the risk of system failures.
