The center line butterfly valve can be divided into the following categories according to the working pressure:(1) the working pressure of the vacuum butterfly valve is lower than the standard atmospheric pressure.
An axial check valve is the preferred solution for critical non-return applications such as the protection of rotating equipment and systems where low pressure loss, stable operation and dynamic behaviour are essential. That means the Axial Flow Control Valve is design for special applications requiring high flow capacity, the precise control from a linear motion closure member, and reduced turbulence and vibrational effects.
Sleeve type soft sealing plug valve according to ANS is applicable to the cutting and connection of pipeline's medium that aroused in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power industry etc. It is under nominal pressure of CLASS150-900LBS, and works at the temperature of -29~180℃.
The centerline butterfly valve by the seal form classification:(1) forced sealing butterfly valve.1) elastic sealing butterfly valve. Seal specific pressure is produced by the elasticity of the seat, seat, or disc as the disc squeezes against the seat while the valve is closed.
Application prospects of triple eccentric butterfly valves: The triple eccentric butterfly valves, as the crystallization of the latest technology of valves, the length of various valves, and the shortness of avoiding various valves, will surely become more and more popular among users. The designer's attention.
