Fixed cone shaft-worm gear-sleeve operated discharge valve for dam and reservoir fresh water

AVK Fixed Cone Valves are purpose-engineered for dam and reservoir outlet discharge applications. The unique inverted cone structure fully dissipates high-flow water’s kinetic energy prior to water contacting surrounding terrain or structures. With atmospheric discharge layout, the valve delivers stable, safe operation and drastically reduces abrasion, erosion and cavitation-related harm to downstream facilities.

Variant 857/1-002
Connection: Flanged
Material: Ductile iron
DN: DN400 - DN1500
PN: PN 16

Features

  • End-of-line design for high-capacity discharge at dams and reservoirs
  • Hydraulically balanced design without differential thrust, low operating torque, compatible with compact actuators
  • Elastomer resilient seat achieving bubble-tight shut-off per EN 12266 Rate A
  • Efficient dissipation of flow kinetic energy before water impacts surrounding structures, minimizing abrasion and erosion, with zero cavitation formed inside the valve body
  • Acid-resistant 1.4401 stainless steel sleeve paired with epoxy-coated ductile iron components for superior corrosion resistance. DN200–DN1000 fitted with fusion bonded epoxy; DN1200–DN2200 supplied with two-component liquid epoxy paint
  • One-piece cast ductile iron body delivering high rigidity and structural strength, with an integrated inverted cone at the downstream outlet for energy dissipation
  • Fully enclosed, grease-lubricated worm- and double bevel-gear drive unit, engineered for long-term maintenance-free operation
  • Precision fine thread drive enables slow actuation, accurate flow regulation, stable positioning, and gradual linear flow variation
