A butterfly valve is a half-turn ball valve, used to control the inward or outward movement of fluid. A small metal disc at the inner side of the valve is placed perpendicular to the direction of flow and rotates one-half of a turn for each full revolution of the valve to be in line with the incoming flow. intermediate rotations allow smooth regulation of internal liquid pressure. The full turn gives full control of flow, allowing the fluid to flow freely out of the cup.

A most common use of a butterfly valve occurs when it is found in conjunction with a temperature range regulator, designed to prevent the flow of excessively hot or cold liquid. Butterfly valves may also be found in emergency shut-off units, which are commonly used in industrial applications to prevent pressure build-up in machinery. Temperature regulators provide automatic shut-off protection in extreme temperature scenarios. This ensures that the system will not damage itself due to overheating or sub-zero temperatures.

In addition to its role as a temperature regulator, the butterfly valve can also be used to prevent pressure buildup. The principle on which the device operates is simple: a small ball (outer ring) is placed into a housing (inner ring). The two areas are then sealed off. When a high temperature is encountered, the seal is broken, creating a leak of pressure. The inner ring then expands to accommodate this increased pressure, resulting in a partial vacuum, until the pressure is equalized with the outside air.

The butterfly valve consists of two rings, the inner ring having a thin metallic wire thread within it. The two pieces are then fastened to each other using a thin metal tab or clip. This design means that the opening and closing members must be complementary in size and shape. This ensures that the valve will close tightly without any leaks.

The two pieces of the butterfly valve are usually made out of brass or copper, with the inner ring being either brass or copper plated and the outer ring being gold plated. A fine layer of wax is usually applied to the inner ring to prevent rusting. The inner disc is then shaped to a certain degree, such that the valve opens and closes within a slightly curved cylindrical passage. To open, the top of the cylinder protrudes outwards, against the inner disc.

In terms of the benefits of butterfly valves, they have numerous benefits. They are highly effective at providing safe and effective relief from pressure, especially from very hot or very cold conditions. Butterfly valves are ideal for use with oil-fired or oil-lubed machinery since they ensure exceptional flow control even under high heat and pressure conditions. This makes them an excellent choice for pressure control applications.
