Taman Tekno Blok F1/F - CDE, BSD, Setu, Kec. Serpong. Tangerang Selatan. Banten 15314, Indonesia.
Fixed cone crank-lever-sleeve operated discharge valve for drinking water and neutral liquids to max. 70°C
The AVK fixed cone (Howell-Bunger) 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 directly into the atmosphere, they operate safely minimizing erosion or other damage to the suroundings.
| Variant 857/0-001 | |
|---|---|
| Connection: | No connection type specified |
| Material: | Ductile iron |
| DN: | DN200 - DN300 |
| PN: | PN 10 |
Features
- End of line installation, for high volume dam or reservoir discharge.
- Hydraulic balance, no differential loads, low operating effort, small actuator.
- Resilient seal for drop-tight shut off.
- Effective dissipation of the flowing water kinetic energy before it strikes any boundary surface, minimum wear/erosion, no cavitation risk.
- Acid proof stainless steel sleeve with epoxy coated ductile iron components for high corrosion resistance.
-
Single piece casted body for rigidity and strength, downstream end is formed as an inverted cone for dissipation of water energy.
-
Profile sealing ring replaceable without disassembling the valve from the pipeline.
-
Fine screw thread for slow speed operation and fine adjustment, good positioning and gradual flow change.
