Hard sealing butterfly valve is to point to: both sides of the sealing pair is metal material or other hard materials. This kind of seal sealing performance is poor, but has high temperature resistance, abrasion resistance and good mechanical properties. For example: steel + steel; Steel + copper; Steel + graphite; Steel + alloy steel. Here also can be cast iron, cast steel, alloy steel, also can be welding, spraying alloy. Soft sealing butterfly valve butterfly valve soft sealing refers to: on one side of the sealing pair is the metal material, on the other side is elastic nonmetallic material. This seal has good sealing performance, but not high temperature resistant, easy to wear and tear, poor mechanical properties, such as: steel + rubber; Steel + tetrafluoroethylene, etc. Soft seal seat is made of a certain strength, hardness and resistance to high temperature performance of non-metallic materials, can make the seal seat zero leakage, but the temperature and the life of the poor adaptability. Hard seal is made of metal, sealed performance is poor. Although some manufacturers claim to be able to make the seal leak, but soft seal cannot satisfy some technical requirements of corrosive materials. Hard seal can be solved, both can be complementary. In terms of sealing, the sealing is good, but now hard seal sealing performance can meet the corresponding requirements. The advantage of soft seal is sealed performance is good, easy to aging, easy to wear and short service life, long service life, but behind the soft seal sealing performance. The structure of the main differences are as follows: 1. Structural differences between soft sealing butterfly valve is in a more linear, hard seal for more eccentric eccentric single, double and triple eccentric butterfly valve. 2. Temperature resistance soft seal is suitable for room temperature environment. Hard seal can be used in low temperature, room temperature and high temperature environment. 3. Soft seal pressure in low atmospheric pressure hard seal can also be used for high pressure conditions. 4. Sealing performance of soft sealing and three partial hardness sealing butterfly valve sealing performance is good, triple eccentric butterfly Industrial Valves in high pressure high temperature environment can maintain good sealing performance. Based on the above characteristics, soft seal butterfly valve is suitable for the ventilation and dust removal pipeline, water treatment, light industry, petroleum, chemical and other industries of bidirectional regulation. Hard seal butterfly valve is mainly used for heating, gas supply, gas, oil, acid and alkali environment. With the widely application of the butterfly valve, and its easy installation, convenient maintenance, simple structure is more and more obvious, the characteristics of electric soft sealing butterfly valve, pneumatic sealing butterfly valve, hard seal butterfly Industrial Valves, etc. In a growing number of occasions began to replace the electric gate and globe valves.
