Reliable partner for butterfly valves with IO-Link position indicator
Step Neuchâtel's wastewater treatment plant wants to incorporate micropollutants in a major project from 2019 to 2025 and treat the wastewater, including micropollutants and nitrogen, even more finely. For the replacement of 18 double-acting pneumatic butterfly valves with position indicators in the biofiltration basins, Step Neuchâtel needs a reliable and flexible partner who offers an attractive price and a good delivery time.
The Step Neuchâtel wastewater treatment plant aims to position itself as a centre of energy recovery for its own 100% covered needs and those of the city of Neuchâtel. The coverage with photovoltaics and heat pumps and the supply of biogas make an important contribution to CO2 neutrality.
Initial situation/Challenges for the customer
Step Neuchâtel's wastewater treatment plant plans to transform itself into an energy recovery centre in a major project from 2019 to 2025. The aim is to incorporate micropollutants once the work is complete and to treat the wastewater, including micropollutants and nitrogen, even more finely.
The replacement of 18 large butterfly valves in the biofiltration basins was not originally planned in the specifications, although the 18 valves had been in use for many years. Later, the project management decided to replace the 18 valves during the conversion. This is to avoid a whole plant shutdown.
With TRI-MATIC we have a reliable partner who offers an attractive price and a good delivery time.
Solution
The 18 double-acting pneumatic butterfly valves with position indicators are used to flush six biofiltration basins. By opening three valves per basin simultaneously, a large flow of water flows and flushes the basin regularly. The function of the 18 butterfly valves is very important for the smooth operation of the plant.
For Sébastien Vuille from the project management, it was crucial that the shut-off valves were supplied in the same material. These are TRI-AIRDISC COMPACT in nominal size 400 with the valve disc in stainless steel and the seal in EPDM. The shut-off valves are also equipped with a position sensor to precisely query the position and connect to an IO-Link system.
For Sébastien Vuille it is clear: "With TRI-MATIC we have a reliable and flexible partner who offers an attractive price and a good delivery time. We feel we are in good hands."
Results
The installation of the 18 double-acting pneumatic butterfly valves with position indicators worked perfectly. Sébastien Vuille and the whole project team are very satisfied with the butterfly valves with IO-Link system, as the position can be displayed and monitored digitally, easily and quickly. This is an important step on the way to alignment by 2025.
