Butterfly valves are also more difficult to operate under high pressure and flow conditions, and they are more prone to leakage. The triple offset butterfly valve design, on the other hand, is better suited to slurries or liquids with solids in the flow because the leading edge allows cutting of potential obstructions.

OF A BALL VALVE?
INTRODUCTION
Butterfly valves and ball valves are both used in flow control applications, where they can be used to shut off or allow flow while also allowing flow regulation in some cases. Both types of valves have evolved to perform exceptionally well in specific environmental conditions and applications. We examine the case for butterfly valve vs ball valve to help you decide which is best for your application.
BUTTERFLY VALVES: HOW DO THEY WORK?
Butterfly valves are quarter-turn valves that use a disc in the center of a pipe to allow or stop flow. Butterfly valves are lightweight and thus require less support, as well as being less expensive than other types of valves. There are, however, a variety of butterfly valves available, ranging from the basic (concentric) option described above to the triple offset butterfly valve design, which was developed specifically for use with harsh chemicals and in slurry or other dirty flow environments. They have a full, zero- leakage design that seals bubble-tight, a mechanism that prevents clogging, and a shut-off feature that means they will last longer. In some ways, a concentric butterfly valve and a triple offset butterfly valve design are very different solutions, let alone when compared to a ball valve.
HOW WORK BALL VALVES?
A ball valve controls flow through it by using a hollow pivoting ball. You can change the size of the aperture and thus the amount of flow by rotating the ball within its housing. They are typically quarter-turn valves, which means that turning the actuator handle 90 degrees provides full flow. The valve control handle is typically aligned with the ball's aperture, allowing for quick visual confirmation of the valve's state.
HOW TO SELECT A BUTTERFLY VALVE VS. A BALL VALVE
The primary point of comparison is price; ball valves are generally more expensive to manufacture and maintain than butterfly valves of equal capacity. Butterfly valves are also more difficult to operate under high pressure and flow conditions, and they are more prone to leakage. The triple offset butterfly valve design, on the other hand, is better suited to slurries or liquids with solids in the flow because the leading edge allows cutting of potential obstructions. Because the valve port can be the full diameter of the pipe, ball valves are generally accepted to seal better than butterfly valves and do not inhibit flow rates when fully open.
When comparing butterfly valves and ball valves, remember that while the ball valve may appear to be a better choice than the butterfly valve for more generalized applications, they are not intended for direct comparison. The triple offset butterfly valve design, in particular, was created for use in very specific circumstances. Butterfly valves and ball valves from industry-leading manufacturers are available from BM Engineering Supplies.
