Flow control for 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.

Flow Control – forward towards fluent flowing

Improving process safety and cutting costs with process ball valves

Ball valves are used in various process industry applications. The most typical solutions are in on-off and ESD applications, but high-performance ball valves are also widely used in control applications. In this article, the author explains by means of a hydrocracker example  how challenging correct valve sizing and valve selection in control applications can be.

Commercial-grade valves in nuclear facilities – a viable way to cut costs and improve safety?

At a time when cutting investment and operational costs is a major target of the nuclear energy sector, engineers and researchers from all parts of the world are on a quest to find the most viable solutions. We, too, decided to look into this problem – to approach it from the perspective of valves. Can these critical components help nuclear power plants save costs?

Common hydraulic valves - the proportional pressure valve

Proportional valves are commonly used to control pressure to a cylinder or hydraulic motor.

How a hydrotreatment plant increased reliability with emergency shutoff valves

To avoid dangerous leaks and the high costs of unnecessary shutdowns, refineries today must be able to rely on the performance of their on-off and safety valves.

Ensuring high uptime with Neles globe valves

Neles globe valves feature uncompromised safety and meet the highest environmental standards. Thanks to the innovative stem sealing solution, emissions from the valves are very low. For applications where zero emissions are a requirement, a special bellows seal solution is available. In terms of reliability and uptime our globe valves have proven their capabilities in even the most challenging process conditions.

Decades of flow control reliability in wastewater sand separation at Salon Vesi

Municipal wastewater treatment is needed everywhere. Even though valves are just one part of the process, they actually play an important role in making the whole process efficient. When the valves are chosen correctly, and they fit the process needs accurately, other parts of the process like pumps wear out less quickly. This was the case at the municipal waste water treatment plant in Salo, Finland.

Flow control for gold production

Optimal valve and pump selection provides savings in gold production in CIL, CIP or CIC circuits. Valmet also has a wide range of solutions for gold autoclave POX process.

Flow control for polyolefins and polymers

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.
