Please provide your technical specifications and project requirements for the Automatic Winged Type Flood Gate V-Gate. Our engineers will review your application and provide a detailed manufacturing quote, including exact pricing and lead times.
The Madoors USA Automatic Winged Type Flood Gate V-Gate is a patented, 100% domestically designed and R&D-engineered automatic hydraulic flood prevention wing door system — detecting flood water levels through electronic switch systems and automatically closing entrances without any human intervention during nights, weekends, and holidays to provide absolute flood security for the protected building. Operating on Siemens PLC with SIM card mobile communication and C## software for fully automatic control, inflating air pressure leak-proof seals that activate after door closure to prevent any water passage to the safe side, hydraulic drive capable of holding tons of floodwater in front of the closed gate, and mobile phone alert transmission when activation occurs, the Madoors USA V-Gate provides the most reliable automatic unattended flood protection available — closing and sealing the entrance at the point where flood water exceeds the safe threshold, with or without any operator present.
TECHNICAL SPECIFICATIONS
The Madoors USA V-Gate is designed in a V-wing configuration — two wing panels open outward in normal operation and close inward in the V formation to seal the entrance under flood conditions. The mechanical strength of the closed V-gate is tested with digital analysis software — the structural engineering of the gate body, hinge system, and seal frame is confirmed by finite element analysis to withstand the hydrostatic loading of the specified flood water depth without structural failure or seal compromise.
The Siemens PLC control unit operates with a SIM card — providing mobile network communication for remote monitoring, automatic mobile phone alerts when flood activation occurs, and remote manual override from any mobile device. The C## software programming provides fully automatic control logic — the PLC monitors the flood water level sensors and electronic switch systems continuously, initiating the gate closure sequence automatically when the water level exceeds the programmed safe threshold without requiring any operator command.
The electronic switch flood detection system detects when flood water reaches the preset danger level — triggering the automatic closure sequence immediately. In normal non-flood conditions, the gate can be activated automatically on a programmed schedule or operated manually with a hand control system. This dual automatic/manual operation mode provides the flexibility for both emergency unattended flood response and routine manual operation.
The hydraulic drive system provides the force required to close the V-wing panels against wind, debris, and initial water pressure — the hydraulic actuation ensures reliable gate closure completion regardless of the loading conditions at the moment of emergency activation. The mechanical construction is very solid — the gate body, hinge system, and frame are engineered to hold tons of water in front of the closed gate throughout the full duration of the flood event.
The leak-proof automatic air pressure inflating seals activate after the door reaches the fully closed position — pneumatic inflation of the perimeter seal closes all potential water infiltration paths, confirming complete isolation of the safe area behind the gate from the floodwater in front. No water can pass to the safe side when the door is closed and the seals are inflated.
Products are manufactured to custom dimensions on a project basis — gate width, height, wing configuration, and structural integration are designed for the specific entrance and structural conditions of each installation.
KEY FEATURES
Fully Automatic Unattended Operation — Night & Weekend Protection
The fully automatic operation without any human control — detecting flood water level through electronic switch systems and closing the entrance automatically — is the critical operational advantage of the Madoors USA V-Gate for the flood scenarios that most frequently cause unprotected losses — the overnight flood, the weekend flood, and the rapid onset storm surge that occurs when the building is unoccupied and no one is present to manually close a conventional flood gate. The V-Gate protects the building itself regardless of occupancy status or time of day.
Siemens PLC with SIM Card — Mobile Phone Alert & Remote Control
The Siemens PLC with SIM card mobile communication provides two critical operational functions — automatic mobile phone notification to the building owner or facility manager when flood activation occurs, and remote manual override capability from any mobile device. The mobile alert directly enables the building owner to monitor and manage flood protection from any location, confirming that the gate has activated and allowing remote intervention if required. The Siemens PLC brand confirms the reliability and service availability of the control system at the highest industrial automation standard.
Patented 100% Domestic Design — R&D Engineering
The patented design confirms the intellectual property protection of the V-gate configuration and the automated flood detection and closure system — the patent directly protects the Madoors USA innovation and confirms that no other supplier can replicate this specific design. The 100% domestic R&D engineering confirms national technology development and supply chain security for procurement by government, military, and critical infrastructure clients.
Digital Analysis Software — Structural Strength Verified
The structural strength verification by digital analysis software — finite element analysis of the gate body, hinge system, and hydrostatic loading — provides the engineering documentation confirming that the gate can hold the specified tons of floodwater without structural failure or seal compromise. This digital analysis documentation supports the engineering submission required for critical infrastructure and government facility flood protection procurement.
Inflating Air Pressure Seals — Complete Leak-Proof Isolation
The automatically inflating air pressure seals that activate after door closure provide the active, verifiable leak-proof isolation that passive compression seals cannot guarantee — the inflated seal conforms to the complete perimeter contact surface, closing every potential infiltration path under the hydrostatic pressure of the floodwater. The confirmation that water definitely cannot get behind the door to the safe side directly provides the absolute security that the V-Gate is specified to deliver.
Hydraulic Drive — Tons of Water Holding Strength
The hydraulic drive provides both the actuation force for reliable emergency gate closure and the holding strength to maintain the closed gate position against tons of floodwater pressure throughout the flood event duration. Hydraulic force output provides the most reliable closure actuation under the adverse loading conditions of real flood emergencies — wind, debris, and partial water ingress during closure are all managed by the hydraulic drive without stall or incomplete closure.
Project-Based Custom Dimensions — Any Entrance Configuration
The project-based custom manufacturing for any desired dimensions allows the V-Gate to be designed for any entrance width, height, and structural condition — the wing configuration geometry, hydraulic drive sizing, and seal system are all designed for the specific entrance requirements of each installation. This custom capability directly enables flood protection at entrances that standard-size products cannot serve.
