5 Multi-phase flow

Flowrox™ slurry knife gate valves

Heavy duty slurry knife gate valve isolates flow even in the most demanding process conditions. The bi-directional flow tolerates backflow and elastomer sleeves on both sides of the gate provide tight shut off. Flowrox knife gate valve follows the concept of the ease of maintenance. The valve body is cast in one piece which eliminates the need for sealing between the body halves. Load distribution ring is integrated into the valve sleeves. The valve contains only two service parts; ring sleeves and secondary seal.

6 Mathematical simulation of control valve behavior

Neles™ R- series segmented ball valve for on-off applications

New Neles segmented ball valve for on-off applications combines the material efficient control valve design with the high capacity and proven performance of Neles on-off valve seating technology. Standard units are equipped with cylinder or manual actuators and intelligent on-off valve controllers to ensure excellent and reliable isolating performance

Valmet - Flow control manual

This manual is intended to give an overview of the role of control valves in the behaviour of a process control loop.

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

We have 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.

Pinch valves

Flowrox™ pinch valves are designed for reliable operation in both isolation (shut-off) and flow control applications. Each valve is built to perform in the most demanding conditions, where conventional valves often suffer from wear due to increased turbulence.
