P Shaped Irrigation Dam Gate Seal Gasket EPDM Rubber Gate Seals

Product Description

Product Description

    is a critical water-stop component for hydraulic engineering gate systems, typically installed around the gate frame or gate body to achieve tight sealing through compression deformation. The product is manufactured from premium rubber or rubber-plastic composite materials via special processes, featuring excellent elasticity, water resistance, and anti-aging properties.

    We can provide international certificates including ISO, CE, and RoHS to ensure product quality meets global standards. It can withstand high water pressure and frequent opening-closing operations, effectively accommodating minor deformations of the gate structure, preventing water leakage, ensuring safe operation and efficient water storage of dams, hydropower stations, and ship locks, and is widely used in various water control hub projects.

Material

are typically made from high-strength rubber, polyurethane, or other corrosion-resistant materials. These materials not only offer excellent sealing capabilities but also withstand high water pressure and the erosion from chemicals.

Function
The primary function of is to ensure watertightness between the gate and the structure, preventing water leakage and protecting the safety of the infrastructure. They also adapt to temperature changes and mechanical movements, ensuring stable performance.

Functions

*High-pressure Sealing: Withstands hydrostatic pressure 0.1-5.0MPa

*Deformation Adaptation: Follows gate operation with 30%-50% compression

*Leakage Prevention: Achieves zero-leakage sealing grade

*Corrosion Resistance: Resists water scour and chemical erosion

*Anti-fouling: Smooth surface prevents shellfish growth

Product Advantages
    *Reliable Sealing: Proven zero-leakage in actual projects
    *High Pressure Resistance: Maximum 5MPa water pressure
    *Long Lifespan: Anti-aging formula for 30+ years
    *Easy Replacement: Modular design, 2-hour replacement
    *Cost Effective: Domestic price with import quality
    *Technical Support: On-site measurement and installation guidance
