The triple offset butterfly valve has a slanting circular shape (the third eccentricity of the so-called triple eccentricity) except that the wide rod and the valve plate have two eccentricities.

Since the introduction of the triple offset butterfly valves for more than 50 years, these 50 years have been continuously developed, and the application of butterfly valves has spanned many industries.

The two eccentricities of the double offset butterfly valve refer to the eccentricity of the rotating center line of the disc and the eccentricity of the sealing line and the eccentricity of the center line of rotation of the disc and the center line of the channel.

The offset butterfly valve is divided into single offset butterfly valve, double offset butterfly valve, and triple offset butterfly valve. A butterfly valve whose valve stem axis is at the same time deviated from the center of the disc and the center of the body, and whose sealing pair is a slanting vertebra is called an offset butterfly valve.

Butterfly valves are very crucial in the improvement of actuators function, thus guaranteeing the good function and longer lifespan of butterfly valve to enhance the whole machine of actuators efficiency becomes imperative, which will be fully explained as below.

As a component used to realize the on-off and flow control of pipeline systems, the center line butterfly valve has been widely used in many fields such as petroleum, chemical, metallurgy, and hydro power.

The butterfly valve has the characteristics of simple structure, small volume, light weight, material consumption, small installation size, rapid switch, 90° reciprocating rotation, small driving torque, etc. It is used to cut off, connect and adjust the medium in the pipeline.

The butterfly valve is a simple regulating valve. The butterfly valve that can be used for the switching control of the low-pressure pipeline medium refers to a valve in which the closing part (the valve flap or the butterfly disc) is a disc and rotates around the valve shaft to open and close.

Butterfly valves are used in a wide range of applications. The variety and quantity used continue to expand, and the development of high temperature, high pressure, large diameter, high sealing, long life, excellent regulation characteristics, and multi-valve. Its reliability and other performance.

The floating ball valve has a simple structure and good sealing performance, but the load of the ball subjected to the working medium is all transmitted to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the working load of the spherical medium.
