Gates

For newly built hydroelectric plants, as well as for reconstruction of existing ones, SDTB “Zaporozhgidrostal” elaborates design of gates, which are an integral and important part of hydrotechnical works. Gates serve to ensure required regulation of water level in reservoirs, to regulate water flow through discharge facilities, to shut off water-conveyance headraces at power plants in emergency cases, to perform repair activities and other functions that ensure safe and effective operation of hydrotechnical facilities.

Types of gates we design depending on their structure:

  • plain wheel gates (if necessary can be equipped with a valve);
  • plain sliding gates (if necessary can be equipped with a valve);
  • radial gates (if necessary can be equipped with a valve);
  • sector gates;
  • doubled gates;
  • valve gates;
  • cylindrical rolling gates.

Types of gates we design depending on their sup-porting and travel mechanisms:

  • sliding gates with metal skid;
  • sliding gates with a skid made of anti-friction self-lubricating materials;
  • wheel gates with projecting wheels;
  • wheel gates with fully-supported wheels;
  • multi-roller gates.
