Reliable flow control keeps tailings operations running smoothly

Tailings handling places extreme demands on flow control equipment. Robust slurry valves and hose pumps help maintain safe, stable and environmentally compliant operation by resisting abrasion, chemical stress and high process loads over long service intervals.

Flow control for energy

Facing increasing pressures to keep your power generating process up to code? Reliable valves and pumps help improve the productivity of your energy plant. We offer reliable valves, pumps and services for the energy industry.

Is your valve maintenance supporting reliability?

We have seen that many plants struggle with finding the right balance in what valves to maintain and when. With our knowledge, we can help you to overcome that challenge.

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.

Why flow capacity matters so much in pulp & paper

Valmet’s control valves sold under the Neles™ and Jamesbury™ brands offer some of the highest Cv-values available on the valve market today. These magical values translate into very concrete benefits for the pulp, paper and board processes our valves serve.

Industries are calling for proven low emission valves

The valve industry is tackling modern day demands with the same tenacity as it started with in the 1980s, when pioneering work in emission management and reduction began, especially in the oil and gas industry. This commitment is particularly relevant as research indicates valves have traditionally contributed up to 60% of the emissions in a running plant.

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.

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.

Flow control for hydrogen production

As the significance of responsible and sustainable industrial processes increases, the role of green and blue hydrogen as carbon-neutral fuel produced from surplus renewable energy or through CO2 removal, respectively, will continue to grow. Find correct flow control for your production.
