Efficient polymerization with the right valves

Although polymerization might look chemically simple, the polymerization process gets tricky with inappropriate valves. If you’re looking for tips on choosing the right valves for efficient plastic production, this blog is for you.

Flowrox control and shut-off pinch valves succeed in ore and water treatment plants in a Spanish mine

After seven years of implementation of Flowrox™ pinch valves in a concentration plant, customer remains satisfied with the cost savings combined with reliable operation and easy valve maintenance. All 330 pinch valves were installed in an extension of their ore and water treatment plant. The project basically consisted of duplicating the size of an existing plant.

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.

The diverse role valves play in the chemical industry

The chemical industry is extremely diverse with more than 60,000 known products. Chemicals are typically split into basic categories including petrochemicals, agrochemicals, specialty chemicals, pharmaceuticals and bio-chemicals, and consumer products. Like all process industries, the chemical industry needs valves designed for safe, efficient and reliable process operation.

Emergency shutdown valves

Reliable intelligent emergency shutdown (ESD) valves and actuators with Neles™ ValvGuard™ intelligent valve controllers improve your plant safety cost-efficiently. At Valmet, we have combined our know-how of valves, actuators, safety standards (IEC61508/61511), applications, system operability and partial stroke test devices with intelligent prediction tools. Diagnostic information is presented understandably to enable planned maintenance of potentially failing valve assemblies before they have a chance to impact the process or safety.

Flowrox valves control sludge flow in a wastewater plant without problems

Flowrox pinch valves PV 500 E01 are successfully controlling the sludge flow in a Polish wastewater plant. Twenty electrically actuated valves were delivered in 2011 to Poland through Danish engineering company Krüger A/S and local Valmet Flow Control channel partner.

Ready for the challenge: Valves enhance fluidised-bed polymerization

The global olefins market is expected to grow by about 4% or more in the next several years. The packaging and automobile industries are ...

Digital hydraulic concept reduces cost and increases reliability

By using digital hydraulics, fragile and expensive proportional valves are replaced with multiple inexpensive and robust on/off valves. The results include higher reliability, lower energy usage, more accuracy in machine movements, fewer shutdowns, less lost production and lower initial investment and spare parts carrying cost.
