 In an industry where technology changes quickly, it's easy to forget the tried and true. But some elements endure for a reason. Plug valves are one such example—tractable in design, reliable in operation, and deployed from water treatment plants to chemical processing plants.   What Exactly Is a Plug Valve?   A plug valve is one of the valve types that utilize a conically tapered or cylindrical plug to regulate the flow of fluid within a pipe. By turning the plug within the valve body, you block the flow or let it flow. It's a very simple mechanism that does not need much to function, making it suitable for systems where durability and quickness are of utmost importance. When Plug Valves Make the Most Sense Not all flow control systems require sophisticated, multi-actuator configurations. In most environments, simplicity is the best choice. Plug valves are commonly used in applications where thick or dirty fluids must travel through a line without plugging. Their...

Amidst all the high-technology automation and remote operation of valves that are so prevalent nowadays, there's still a lot to be said in favor of the reliability and simplicity of a manual butterfly valve. It has no whistles and bells of the electric or air-actuated variety, but for most situations, that's the idea—it simply works. If you're dealing with fluid flow through a pipeline, process plant, or even a water supply network, there's a fair chance you've used butterfly valves along the way. Their disk design is perfect for tight spaces, quick shut-off, and safe closure, and the manual version provides full control without reliance on an external power source. Why Manual Still Makes Sense Not every valve needs to be installed in a smart system in the first place. In most plants and applications of utilities, manual butterfly valves are applied only because they are convenient to operate, don't need any complicated wiring, and can be fixed or replaced with...
