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.
Our product offering
Neles™ Capping valves
Neles series PZ capping valve offers a solution for automatic opening and closing of batch digester for chip fill. Capping valve increases considerably digester chip fill process efficiency and operator safety.
Neles™ modular pocket feeder valve
Neles M series pocket feeder valve for separator service in pulp and paper industry is designed for automatic removal of sand and other fine debris from the process. Typical applications are the chip chute circulation process of a continuous pulp digester and other junk traps. Complete unit consists of a full-bore ball valve, pneumatic actuator, limit switches and solenoids for purging the interior cavity of the valve.
NelesAce™ basis weight control valve
NelesAce is the ultimate solution for basis weight control which is one of the most critical applications for a valve in a paper machine. The unit consists of a reliable V-port segment valve, complete with a high-resolution step-motor-driven rotary actuator, limit switches, and potentiometer.
Neles™ MC V-port segment valves, series R2
Neles has created a specially designed series R2 segment valves for 8-19 % medium consistency applications. The valve provides an optimized flow path for medium consistency pulp. The flow path is continuously increased to eliminate restrictions where material may build up. The outlet flange is one size bigger than the inlet to ensure this. V-contoured flow path enables to control small capacities without risk of dewatering.
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.
