Application specific products

The right valve makes all the difference

Sometimes the right valve simply has to be designed, engineered, manufactured, tested and optimized for a very specific task. Neles™ provides a portfolio of application-specific valves such as capping valves used in batch cooking or pulp and paper process -specific valves such as the NelesAce basis weight control valve or pocket feeder or high consistency segment valves.

Industry specific expertise

Neles has a long history of serving customers in the pulp & paper industry. With the first valve deliveries going back decades, it is no wonder that many of the highly customized application specific valve products have been designed and manufactured for use in this industry. These solutions often consist of complete valve assemblies based on stock products, customized and paired to achieve the desired results. If you are faced with a valve application that requires something that is not yet offered, don’t hesitate to get in touch. We at Neles are born problem-solvers and always ready to explore new solutions together with our customers.

Targeted product innovations

A great example of an application specific product in the Neles portfolio is the NelesAce basis weight control valve. It is a product specifically developed to meet the critical accuracy requirements of basis weight control on a paper machine. The custom valve assembly consists of a reliable V-port segment valve, high-resolution step-motor-driven rotary actuator, limit switches and potentiometer. Other pulp & paper industry-specific valves products include our Neles M pocket feeder valve for separator service, helping remove fine debris from the process, and our PZ series capping valves.

Some innovations, such as our high consistency segment valve, is designed for a specific medium and consistency rather than a process. We have created the R2 series segment valves specifically for 8-19% medium consistency pulp. The flow path is continuously increased to eliminate restrictions where material build-up may occur. To ensure this, the outlet flange is one size bigger than the inlet.
