Professional Analysis of Butterfly Valves and High-Precision Valve Parts Production
A key advantage of selecting a butterfly valve is the reduction of space and weight to a system compared with other options such as ball, check, globe or gate valves.
Butterfly valves belong to the family of quarter-turn rotational valves, created and first used in steam engine prototypes as early as the 18th century. Use of butterfly valves grew in the 1950s for applications in the oil and gas market, and 70 years later they continue to be widely used in numerous industrial applications.Butterfly valves belong to the family of quarter-turn rotational valves, created and first used in steam engine prototypes as early as the 18th century.

Butterfly valves can be assembled with handles, manual gears, pneumatic or hydraulic actuation. The valve configuration consists of a stem and disc that rotate 90° from open to close in the clockwise direction. Butterfly valves are popular in many applications as they are cost effective to maintain, offer fast operation and are lightweight compared to other types of valves. Most butterfly valves use the same basic configuration, with a body, stem, disc, seat and stem seal; however, other parts may vary between the different butterfly valve types, such as resilient seated, lined, single offset, double offset (often referred to as high performance) and triple offset. These types are differentiated by the geometry of the disc, stem, seat and the material of the seating designs.
A key advantage of selecting a butterfly valve is the reduction of space and weight to a system compared with other options such as ball, check, globe or gate valves. Compared to a gate valve, installation of butterfly valves is less difficult from size and weight, and compared to ball valves, the cost to replace or repair is usually less. Butterfly valves are limited based on their application as they have an obstructed port, as part of the disc always faces the flow even when fully opened and they are not typically utilized in heavy slurry applications as a knife gate or severe service ball valve is preferred. Butterfly valves are also versatile products that can be used in both isolation and light control/throttling services.
