Wastewater Treatment

Society’s desire for a clean environment shines light on the importance of understanding the essential role wastewater treatment plants have in our communities. Congress passed the Clean Water Act in 1972 to control the discharge of effluent into water systems and waterways, and provided grants to allow municipalities to meet these new requirements. Since then, technologies such as optimized treatment systems and automated valves have been used to make our country’s wastewater plants technical marvels. The purpose of this article is to explain the various critical roles that valves play in the operation of typical wastewater plant processes.

Food and Beverage Processing

When wandering the grocery store aisles, it’s easy to forget that for every colorful package that sits on the shelves, a myriad of processes go into preparing the foods inside. Whether it’s cereal, breakfast pastries, cookies or canned peaches, everything must be either steamed, dehydrated, pulverized, pasteurized or otherwise treated to fit into the cans, boxes and cellophane packages.

Offshore Oil Extraction and Transportation

Offshore oil facilities come to the forefront of our thinking these days only when a catastrophic accident occurs aboard a platform or other facility. That’s because they are generally out to sea and out of sight. It’s difficult to comprehend the varied and complex piping systems that allow a rig or a drill ship to operate successfully and safely, but they’re an integral part of what’s happening every day. These piping systems contain a multitude of valves built to multiple specifications to handle a variety of flow control challenges. They also control various system loops and contain pressure relief devices.

Pipeline Valves—Always Ready


From time to time, we will re-post particularly well-received articles that have previously run on VALVEMagazine.com so that those who might have missed them will be able to catch up on the best of the best. This article on Pipeline Valves, initially ran on November 7, 2011.

This nation is crisscrossed by hundreds of thousands of miles of crucial pipelines that transport vital feedstock from sources to the places where it’s transformed into fuel and products. For the valve industry, that translates into millions of dollars of business.

Power Plant Isolation Valves Beat the Heat

About a century ago, pressures of 300 psi and temperatures of 400°F (204°C) were normal for steam power plants. The next 50 years would see constantly rising pressures and temperatures as the quest for higher efficiency ­proceeded. By the end of the 1950s, temperatures approached 1200°F (648°C) and pressures above 4,000 psi were benchmarks for generating steam power in the supercritical (SC) range. As these new benchmarks have been achieved, the design of isolation valves used in these plants has changed, from cast iron T-pattern globe valves to 9 chrome pressure seal gate valves.
