VACOMASS Binder Jet Control Valves have been designed specifically for precise control of aeration in waste water treatment plants. VACOMASS Binder Jet Control Valves are available in sizes from 250 – 400mm they can accurately control air from 80 – 13,500Nm³/h (95 – 9,700SCFM) and have a linear control curve from 0 – 95% of their stroke. This leads to vastly improved DO control and in most cases leads to the DO set point being lowered, thereby saving significant amounts of energy. Pressure loss over a Jet Control Valve is also extremely low (particularly compared to the traditional butterfly valve) meaning that often very reasonable pay back times can be achieved without factoring in a lower DO set point (which improves the payback yet again).
The traditional aeration control valve in New Zealand is the butterfly valve which has a very unstable control curve leading to unstable DO values and they also have very high pressure losses – typically around 50 – 80mbar. The VACOMASS Jet Control Valve by Binder is the perfect answer to these issues.
