VACOMASS Binder Jet Control Valves
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.
