What is a high-pressure butterfly valve and how does it work?

A high-pressure butterfly valve controls the flow of liquids or gases through a pipe using a rotating metal disc — when fully closed, the disc blocks flow, and when open, it rotates 90 degrees to allow fluid to pass through freely.

What industries and applications are high-pressure butterfly valves best suited for?

They are well-suited for oil and gas, chemical processing, power generation, water treatment, fire protection, agriculture, and any application involving compressed air, high-temperature steam, or high-pressure water services.

How do butterfly valves help prevent water hammer?

Butterfly valves’ efficient sealing and precise flow control help mitigate the sudden pressure surges caused by water hammer, reducing the risk of pipe rupture, collapse, vibration, and noise.

Are there any limitations to using a butterfly valve?

One notable limitation is that butterfly valves cannot be “pigged” for cleaning — a maintenance process that uses specialized devices to clear the interior of a pipeline — which may make them less ideal for applications requiring that type of upkeep.

What material is best for butterfly valves handling corrosive fluids?

Brass butterfly valves are typically the best choice for corrosive environments, though they should not be used in systems with high chlorine content in the water, as chlorine can degrade the valve material over time.
