Brief introduction of high temperature butterfly valve model

Presumably many friends know that there are many models of high temperature butterfly valves, which can be installed and connected in the form of (wafer, flange, welding), transmission (electric, pneumatic, hydraulic), and structure (single eccentric, double eccentric) , Triple eccentricity) and sealing materials. Today we mainly introduce the hard-seal double eccentric model of high temperature butterfly valve.

     Double eccentric metal hard-seal high temperature butterfly valve is one of the main equipment used in the outlet of the main fan of the catalytic cracking unit. In addition, it can also be used in important industrial equipment such as petroleum processing, electric power, papermaking, metallurgy, aerospace technology, etc., instead of Gate valves, globe valves, throttle valves, etc.

     The working principle and characteristics of this high temperature butterfly valve model: ①Double eccentric; ②Metal seal, the curvature of each point on the sealing surface is different, no relative friction is generated, and the service life is long; ③The additional torque is large, and the medium is sealed in both directions; ④The sealing surface has a large rising angle, Eliminate the jamming phenomenon; ⑤Composite metal seal, good elasticity and reliable sealing.

     The overall level of main technical and economic indicators of high temperature butterfly valve:

     Nominal pressure and caliber: PN16 DN80~1200,

                                                      PN25 DH80~500;

     Working temperature: main material: stainless steel -196~600℃;            

     Main body material: carbon steel: -40~425℃.
