Soft seal: The side of the seal pair is metal material on one side and soft non-metal material on the other side. This kind of seal has good sealing performance, but it is not high temperature resistant and easy to wear. Poor mechanical properties, such as: steel + rubber; steel + tetrafluoroethylene and so on.
Hard seal: The two sides of the seal pair are metal materials or other hard materials called "hard seal." This seal has poor sealing performance, but it has high temperature resistance, wear resistance, and good mechanical properties.
Soft seal refers to the use of materials with relatively low hardness on one side of the seal pair. In general, soft seal seats are made of non-metallic materials with certain strength, hardness, and temperature resistance, and have good sealing performance and can achieve zero leakage. , but its life and adaptability to temperature are poor.
Hard seals are made of metal and have relatively poor sealing performance, despite manufacturers claiming zero leakage.
Soft seal gate valve has the advantage of good sealing performance, the disadvantage is easy to aging, wear, short service life. Hard seals have a long service life, but are less sealable than soft seals. These two kinds of seals can complement each other, and soft seals are relatively good in terms of sealability, but now the sealability of hard seals can also meet the corresponding requirements.
