      The EUROSTOP Buried version is specifically designed for direct-buried installations, eliminating the need for costly concrete chambers. Featuring a specialized IP68 watertight gearbox and a reinforced protection system, this valve ensures smooth operation even when submerged or installed in aggressive soil conditions. It is the ideal choice for modern water distribution networks looking to optimize installation costs without compromising on safety.

      Applications: Water Irrigation

      Key Advantages 

      • Watertight Integrity: Equipped with a dedicated IP68-8 gearbox featuring a sealed cover to prevent any water or debris ingress, ensuring functionality over decades of burial.
      • Cost-Efficient Installation: Designed to be buried directly in the soil, significantly reducing infrastructure costs by avoiding the construction of manholes or valve pits.
      • Enhanced External Protection: In addition to the standard 250 μm epoxy coating, the gearbox receives an additional 80-micron blue epoxy layer for maximum corrosion resistance.
      • Seamless Extension Connectivity: Features a mounting flange (ISO 5210 F10/F14) designed for quick and secure coupling with extension spindles and operating caps.

      Essential Accessories for Buried Valves

      To ensure a complete and functional installation, the EUROSTOP Buried version integrates perfectly with:

      • Telescopic Extension Units: To adjust the manovra point exactly to the ground level regardless of burial depth.
      • Operating Caps & Couplings: For easy operation via standard T-keys.
      • Surface Boxes To protect the top of the extension unit at the street or pavement level.
      • Position Indicators: Specialized headstocks with visual indicators for buried service.

      Applications

      • Urban Water Networks: Reliable isolation for underground pipelines in city streets.
      • Cross-Country Aqueducts: Long-distance pipelines where valve chambers are impractical.
      • Irrigation Schemes: Direct burial in agricultural fields with protection against moisture.
