ARI® steam boiler technology
Safety and efficiency from one source
A steam boiler is at the heart of many industrial processes. It converts feedwater into valuable steam, which is required in power plants, refineries and in the chemical industry. To ensure this process operates safely, reliably and efficiently, valves are crucial as they regulate, isolate and safeguard the entire operation.
From feedwater to steam
Starting from the feedwater tank, the treated water passes through pipes and valves such as control valves, check valves, isolating valves and strainers to the boiler. Here, it is heated in the combustion chamber and turned into steam. Integrated preheaters also boost the energy efficiency.
Targeted control and safety
The steam produced is circulated via high performance butterfly valves, safety valves and automated valves to the connected systems. To ensure the pipes remain free of disruptive condensate, steam traps ensure that dry and safe steam is supplied. At the same time, the gas flow with isolating valves guarantees precise and safe fuel supply to the boiler.
Solutions from a single source – our one-stop shop
What makes this boiler process special is that all the components described – from control valves to isolating valves, check valves and steam traps to strainers – come from the same place. As a manufacturer, we offer a range of valves for the medium pressure range, perfectly coordinated and from a single source.
What does this mean for you?
- One partner, one solution – reducing the supply chain and coordination involved
- Optimal compatibility – all valves are coordinated
- Maximum reliability – proven quality for safety-critical applications
With our one-stop shop for steam applications up to 160 bar, you can obtain a complete solution from one source – one that is safe, efficient and reliable.
ARI® valves in action: Steam boiler application example
The diagram shown here depicts a symbolic steam boiler that can generate pressures between 60 and 163 bar. Valves play a crucial role in ensuring that this process runs safely, efficiently and reliably – they regulate, shut off and secure the entire operation.
