Valves for water and wastewater industry

Have you found a partner who can deliver on both innovative solutions and reliability requirements for your water and wastewater treatment plants or other water transport application? We offer pumps and valves that are able to withstand some of the most demanding applications.

Common challenges in water treatment

Isolation and control are the two most important words in the environmental industry. Mostly, industrial water treatment and wastewater industries include highly abrasive and corrosive applications which call for heavy duty equipment. On top of withstanding those demanding processes, the equipment needs to be safe and reliable.

For example, most wastewater treatment plants use ozone, UV or chemical treatment. Each of them presents either high energy costs, issues with turbidity or chemical handling risks. With heavy duty products and solutions targeted at this industry, we generate savings in water, waste, wastewater and process fluid handling while promoting overall safety.

Reliable valves, pumps and services for water industry

We offer flow control solutions that can be customized to fit any application within the water and wastewater industry. Whether it’s protection from abrasive or corrosive applications, our valves will protect the environment while keeping the performance on a high level. Flowrox™ pumps withstand the most demanding process applications while offering safe and reliable equipment you can count on.

With a creative, solutions-minded valve and pump partner, you can make water treatment and the handling of wastewater more sustainable and quieter. Reliable, industry-proven valves protect infrastructure investments from shutdown, safeguard neighborhoods and help avoid any legal or reputational risks of unsafe applications control.

What it takes to keep it flowing

At Neles™, we leverage 65 years of research to engineer for the toughest municipal and industrial water treatment or wastewater challenges. Our experience with custom assemblies and cost-constricted projects ensures valve solutions that offer the best value for the stakeholders you serve.

Our valves and pumps are designed to help you safely optimize flow through pump control stations and assemblies requiring special surge equipment and safety shutoffs. They protect against reverse flow or prevent slamming problems. Each valve is designed to reduce clogging, ensure purity and increase reliability. We also provide end-to-end valve packages that resist corrosion and allow easy maintenance access.

Control valves

Control valves are the most important part of any process control loop, vital in stabilizing processes. Neles™ control valves are engineered, manufactured, tested and optimized for your specific application. Our flow control solutions offer reliability, productivity, and sustainability, allowing you to maximize your output and profitability.

On-off valves

Intelligent, reliable on-off Neles valve solutions for general and high-cycle applications will help to reduce the life-cycle costs. Our valve solutions provide long lasting tight shut-off with fast and safe operation together with reduced fugitive emissions. Neles shut-off valves combined with intelligent valve controllers provide diagnostic capabilities and increase plant safety.

Pinch valves

Flowrox™ pinch valves can be either used for shut off, also known as isolation, or control. Every Flowrox pinch valve is fit for the most demanding applications in which conventional valves encounter problems with wear due to increased turbulence.

Emergency shutdown valves

Reliable intelligent emergency shutdown (ESD) valves and actuators with Neles™ ValvGuard™ intelligent valve controllers improve your plant safety cost efficiently. In Neles we have combined our know-how of valves, actuators, safety standards (IEC61508/61511), applications, system operability and partial stroke test devices with intelligent prediction tools. Diagnostic information is presented understandably to enable planned maintenance of potentially failing valve assemblies before they have a chance to impact the process or safety.

Valve automation excellence

Neles valve automation offering ranges from limit switches to reliable actuators and intelligent valve controllers with third generation diagnostics.

Valve controllers

High availability and easy interpretation are the key success factors in effective field device data analysis. Neles valve controllers support standardized technologies and ensure the availability and usability of diagnostics information independent of your control, safety or asset management system.

Valve services

Reliability is at the core of every successful process plant’s operations. Neles is your reliability partner for valve services.

Flowrox™ LPP-D dosing pumps

Flowrox™ LPP-D pumps are ideal for dosing and flow control. The dosing pumps provide accurate dosing in all process conditions as the pump discharge flow does not depend on the pipeline pressure. There is no variation due to the discharge pressure condition, output remains the same on every cycle. They are ideal for demanding process media.

Flowrox™ LPP-T peristaltic pumps

Flowrox™ LPP-T transfer pumps incorporate advanced single roller design which eliminates friction and lowers energy consumption. They are ideal for pumping various slurries and dosing a wide range of abrasive, corrosive, viscous or crystallizing media.

Insights into water industry

Outstanding performance and zero maintenance with reliable Flowrox pinch valves

Reliable Flowrox™ high performance PVE pinch valves proved to be a perfect solution for a power generation water treatment plant located in Mpumalanga, South Africa. Six years after the installation of PVE pinch valves in power generation plant no maintenance has been required.

Celebrating 65 years of flow control
