1. Pure Physical Drive, Power-free Automatic Response
Operating on pure physical principles, the hydrodynamic full-automatic flood gate requires no power supply or manual activation. It opens and closes automatically in response to water level fluctuations.
2. Unattended Intelligent Operation with Flexible Control
The gate enables unattended automatic flood blocking and activates autonomously in case of flood backflow without on-site personnel operation. Manual opening is also available to facilitate routine maintenance and pre-emptive flood defense, featuring flexible operation and strong adaptability.
3. Concealed Installation Without Hindering Passage
Embedded concealed installation is supported. The gate can be installed flush with the ground without occupying space or damaging the original building structure. Surface-mounted installation is also an option, with the additional function of a speed bump. Suitable for underground parking garages, metro stations, underground shopping malls, civil air defense projects, power substations and other sites, it does not interfere with pedestrian and vehicle traffic.
4. Proven in Practical Scenarios with Excellent Performance and Reputation
The hydrodynamic full-automatic flood gate has been verified in real flood events with stable performance and powerful protection capacity. Nearly 1,000 sets have been installed worldwide, successfully blocking floodwater close to 100 times, achieving a 100% flood interception success rate.
