Neles™ Q-Disc™ flow balancing trim for Neldisc™ butterfly valves

New, patent pending Q-Disc design features extreme flow balancing for control service. Dynamic torque effect from the flow has been significantly reduced allowing high pressure drop service. Design also provides market leading noise reduction even up to 12 dB.

Life-long capping valve performance

Neles’ flow control solutions offering for the pulp and paper industry covers all the typical valves, a wide range of accessories, intelligent devices and software solutions and of course comprehensive services.

Neles Easyflow™ JT series angle stem tank bottom valves

Neles Easyflow JT series angle stem tank bottom valves provide a compact assembly with additional space for actuator clearance on insulated vessels. Large port has unobstructed flow to empty or fill the tank quickly. Quarter-turn operation and direct actuator mounting capability makes it easy to automate. Cavity fill and T-port options for the JT series ensure lowest possible dead volume and full draining of media from the valve.

Navigating high temperature challenges with Neles™ Neldisc™ butterfly valves

As process temperatures go up, the challenges for the flow control equipment increase gradually. Stepping above 250 °C requires most of the plastics and polymers to be abandoned and the selection of metallic materials instead. Furthermore, when the temperature rises above 600 °C, the challenges with the suitability of the materials require even more careful attention.

Flow control for compressor stations

Valmet has a complete line of valves and flow control services designed to improve compressor stations' efficiency.

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.

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.

How to eliminate erosion and abrasion caused by catalyst fines in FCCU?

This entry describes how an installed Neles erosion/abrasion resistant ceramic valve solution has helped a customer improve FCC unit performance and profitability. In this particular case eroding 2″ to 10″ valves in a refinery’s fluid catalytic cracking (FCC) unit were causing problems that degraded both productivity and profitability. Neles application engineers analyzed the problem and provided a solution that quickly paid itself back many times over.
