化工行业的各种阀门应用

Valves for petrochemical applications
Today’s petrochemical producers face ever-increasing regulatory, environmental and performance demands. Now, more than ever, you need more than just a valve supplier. You need a reliability partner who offers deep application knowledge with a complete offering of technologies, customer support and services.

Ethylene and propylene processing
Steam cracking plants, which produce ethylene, are divided into three sections which together represent a very demanding environment. Propane dehydrogenation uses propane to produce high-quality propylene. Our valves offer the highest reliability throughout every step of the demanding process.

Polyolefins and polymers processing
Polyolefin technologies include gas-phase, slurry, high-pressure, mixed-phase, and solution processes. Our valves have been developed to operate in extreme conditions, dealing with an abrasive flow media at very demanding cycling requirements.

Valves for chlorine service
Chlorine service is notoriously challenging. It’s highly reactive as a liquid or gas and can easily go from a revenue generator to personal or environmental catastrophe if extreme precautions are not taken. Chlorine applications are not for the inexperienced or unproven.
Insights into chemical industry

Q-disc™ – Born to perform under pressure
Valmet’s Neles™ Q-disc™ flow balancing trim is all about reducing noise and taking off some of the pressure directed onto the disc and shaft of a butterfly valve. It is able to do both things with great efficiency and reliability thanks to unique features such as the perforated design and fixed integration onto the disc.

Merger of Valmet and Neles: Forward together from a stronger base
Over the years, Neles and its predecessors have developed capabilities that position us as a best-in-class player in our field. Now, we look forward to accelerating this agenda as part of Valmet. The key message to our customers is: our capabilities and know-how are even stronger. In fact, we are operating from a stronger base and with wider offering, covering more markets and leveraging our global reach in a more efficient manner.

Rubber hose solves scaling issue -Increased uptime and process efficiency with Flowrox pumps
A smelting plant in Norway had a scaling problem. Their spill process water contains lots of carbonates which caused reoccurring damage to the previously used centrifugal pump. Another challenge for the new pump was to also empty the 3-meter-deep tank located underneath the pump’s location.

Thriving in demanding petrochemical applications
The petrochemical industry presents valve solutions with demanding applications and operating environments. Reliable flow control solutions are vital in terms of both process quality and operational safety. Neles offers a full range of flow control solutions from valves and actuators to intelligent valve controllers for the wide range of petrochemical processes and applications.

Service is a key benefit of the product itself
Neles butterfly valves are a trusted part of many industrial processes the world over. There are currently more than a quarter of a million butterfly valves installed around the globe. And this number only includes the valves in our installed base database. In addition to the products themselves our service expertise is often a key reason behind many clients selecting our butterfly valves.

12 recommendations to minimize capital project start-up problems and lower total cost of ownership
