Business Development Manager Dams, Reservoirs & Hydro

Submerged discharge valve for dam and reservoir fresh water.

The AVK submerged discharge valves are designed to safely dissipate the surplus energy from large amounts of rapidly flowing water. Installed at the outlet of dams or reservoirs and discharging sub-surface into a stilling basin, they operate with a minimum of noise and a maximum of safety.

Variant 856/1-001
Connection: Flanged
Material: Ductile Iron
PN: PN 16

Features

  • Terminal discharge valves situated at the end of the pipeline and are installed in a compact stilling sump
  • Stilling sump providing submerged discharge with safe and quiet energy dissipation
  • Hydraulic balance, no differential loads, low operating effort, small actuator
  • Resilient seal for drop-tight shut off
  • Submerged discharge, safe, quiet energy dissipation and cavitation free
  • Chloride resistant stainless steel internal parts, bronze ported body with epoxy coated ductile iron components for high corrosion resistance
  • Shaped multi-ports giving wide control range, can be customized for specified condition
  • External mechanism allowing easy maintenance and visible indication
  • Fine screw thread for slow speed operation and fine adjustment, good positioning and gradual flow change
