Mental seat butterfly valve and resilient butterfly valve difference

Butterfly valve mental seat refers to: both sides of the seal pair are metal materials or hard other materials. The sealing performance of this seal is poor, but high temperature resistance, wear resistance, good mechanical performance.

Butterfly valve resilient refers to: one side of the two sides of the seal pair is metal material, the other side is elastic non-metallic material. The sealing performance of this seal is better, but it is not resistant to high temperature, easy to wear, poor mechanical property.

resilient seat is made of non-metallic materials with certain strength, hardness and temperature resistance. Good performance can make zero leakage, but its life and adaptability to temperature are poor. The mental seat is made of metal, and the sealing performance is relatively poor. resilient can not meet the technological requirements for some corrosive materials. A mental seat can be solved, and the two seals can complement each other. As far as the tightness is concerned, the resilient is relatively good, but now the tightness of the mental seat can also meet the corresponding requirements. The advantage of resilient is good sealing performance, the disadvantage is easy to aging, wear, short service life. The service life of mental seat is long, but the tightness is worse than that of resilient.
