Water treatment is a multi-stage and precisely controlled process in which every component affects the quality, safety, and cost-efficiency of the final result. Valves play a critical role in this system: they do not merely open and close flow, but also regulate pressure, guide water flow, and protect the system from disturbances. Correctly selected valves enable a smooth and controlled water treatment process, from raw water intake to wastewater treatment.
A reliable valve is a decisive factor in process efficiency and equipment longevity. An incorrect choice can lead to leaks, corrosion, blockages, or even production downtime—issues that can be prevented with expert design and the selection of appropriate valve solutions.
Selection criteria – When conditions define requirements
Valves in water treatment processes are subjected to demanding conditions. They must handle varying flow rates, pressures, temperatures, and often chemically aggressive media.
Selection depends on factors such as:
- The process medium (clean water, turbid water, chemicals)
- Pressure and temperature conditions
- Requirements for shut-off, regulation, or flow control
- Maintenance reliability and operational dependability
- Installation environment, which imposes requirements on design, sealing, and operation
Material and seal selection is critical, as aggressive chemicals, such as chlorine or acidic solutions, can quickly compromise unsuitable materials. Similarly, sludge and sediments increase wear and the risk of blockages, highlighting the importance of durable designs. Considering these environmental factors during the design phase ensures that valves withstand operational conditions, protect equipment, and enable flexible process control.iden huomiointi jo suunnitteluvaiheessa varmistaa, venttiili kestää käyttöolosuhteet, suojaa laitteistoa ja mahdollistaa prosessin joustavan hallinnan.
Efficiency and control through automation
In modern water treatment plants, valves are often integrated into automated control systems. Actuated valves allow precise regulation of flow rates, pressures, and levels, improving process control and energy efficiency. Intelligent control solutions can also collect data on valve performance, wear, and actuation cycles, facilitating predictive maintenance.
Automation enables seamless integration of valves into the plant’s monitoring system, allowing process loads to be optimized and disturbances to be addressed quickly. This not only reduces risks but also enhances production continuity and lowers overall costs.
Practicality and maintainability
The operational reliability of water treatment systems largely depends on how easily and quickly valves can be serviced or replaced. Modular structures, standardized connections, and good spare parts availability facilitate maintenance and reduce downtime.
Predictive maintenance extends the service life of valves and reduces unplanned shutdowns, ensuring that the water treatment process operates without interruption.
ECONOSTO offers customers valve maintenance, servicing, and testing services that support the long-term operational reliability of plants. Our maintenance services cover valve inspections, refurbishments, and testing, and can be flexibly implemented throughout Finland, either on-site at customer premises or at ECONOSTO’s service facilities in Kuopio or at our parent company KLINGER Finland’s workshop in Masala, Kirkkonummi.
Valve solutions for water treatment needs from ECONOSTO
Our wide range covers all the most common valve types and material options, such as butterfly valves, soft sealing gate valves, knife gate valves, check valves, bottom valves, safety valves, and pressure reducing valves. Additionally, customized valve solutions are available when process conditions or special requirements demand more than standard solutions, for example, high temperatures, corrosive substances, or exceptional flow conditions.
As part of KLINGER Finland, we are also able to offer a wide selection of gaskets as well as camera surveillance and machine automation components.
Many valve models are available directly from stock, enabling fast deliveries even in urgent maintenance situations. Valves can be equipped with electric or pneumatic actuators as well as extension spindles, which increases application possibilities and control features in different processes.
