Innovation, cutting-edge technology, and customer satisfaction are the key foundations of the products and services The Macomb Group offers its customers. One of the ways we meet our high standards is to partner with companies that also believe in these ideals. This way we can ensure that we continually exceed expectations, allowing us to remain the top provider of pipe, valves, and fittings (PVF) for the Midwest region and beyond.

Our partnership with Flowrox — a leading provider of heavy-duty valves, pumps, and systems — began 10 years ago. We selected Flowrox due to their robust product line, which offers the utmost reliability, lowest cost of ownership, and — most importantly — longest operating time. Flowrox increases customers’ productivity by offering them products and services that improve efficiency and extend service intervals. Flowrox solutions provide the highest level of performance with trouble-free operation.

Flowrox pinch valves solve the critical issues at electric power generating plant

PVG_M-and-A_PNGIn July 2018, we were approached by the Longview Power Plant in West Virginia to replace two ceramic-coated ball valves with automated pinch valves for a slurry application. At the time, their valves needed to be replaced every three to four months and they decided it was time to find a more robust solution to meet their needs.

After evaluating the situation, the most obvious solution was to install new double pinch valves with modulating actuators for precise flow control. The pinch valves are specifically designed for slurry applications, with an expected two- to three-year liner life. They also provide a reduced installation time and better position control for flow.

We were able to work with Flowrox to design a solution and provide the Longview Power Plant with two new double pinch valves with modulating actuators for direct replacement of their 4-inch ball valves. We were also able to save them time and money by supporting the installation with an on-site team assisted by Flowrox. We tested the units prior to shipping, and our team did a follow-up visit to ensure the valves/actuators were functioning as designed.
