Do they stop your heart when they do a valve replacement?

In nowadays cardiac surgery the heart is not stopped completely for a conventional valve replacement. Sophisticated methods enable surgeons to operate on a beating heart, or to place patients on a heart-lung machine that temporarily assumes circulation. The accuracy and scrutiny in this process have an analogue in industrial fluid systems. As surgeons try not to stop the heart unless they must, engineers try to sustain flow and pressure with as little system disruption as possible. That’s when selecting the right pipeline valve is most important. The Cast Iron Lug Butterfly Valve, the Wafer Type Butterfly Valve, and the Flanged Butterfly Valve​ are designed to manage, isolate, or regulate flow without needing a complete system stop for the duration of their operation.

The Cast Iron Lug Butterfly Valve​ is developed for isolation. It has threaded lugs on both sides of the body. Bolts are inserted through these lugs to hold the valve between the flanges during installation. The best feature of this design is the ability to shut off a portion of the piping for service. By turning off the valve and removing the nuts on one side, a section downstream can be isolated without disrupting the flow upstream. This makes it indispensable for applications in water supply, HVAC and industrial systems in general where process flow cannot be interrupted for maintenance.

For straightforward open/close operation when space and cost are at a premium, the Wafer Type Butterfly Valve​ is the standard offering. This valve is slim and lightweight, and is mounted by bolting sandwiched between two pipe flanges with long bolts that go through the entire assembly. Although it can not be used for line isolation like a lug valve, its compact design results in a lighter weight and lower cost. It finds its application in medium pressure water and air and other compatible media in which there are already other forms of isolation in the pipeline design.

When strength is required for a permanent leak-tight seal, the Flanged Butterfly Valve is the best answer. The valve features integral flanges at each end which are either cast or welded on which bolt directly to the mating pipeline flanges. This designs creates a much stronger joint for higher pressures and more severe service than wafer or lug designs. It is the standard valve for permanent installation in water treatment plants, in the processing of chemicals and in any heavy duty application in which reliability cannot be compromised.

In medicine and engineering alike, success is predicated on having the right tool for the job. From a Cast Iron Lug Butterfly Valve for a water line, a Wafer Type Butterfly Valve to control air flow, to a Flanged Butterfly Valve for a chemical process, the right selection means your system will run smoothly, safely and efficiently - keeping the heart of your process pumping strong.
