Pneumatic hard sealing and soft sealing gate valve is the main difference

in the market for a long time to use the general gate there is a widespread leakage or rusty phenomenon, pneumatic valve pneumatic valve overcomes the general soft sealing gate lock pneumatic valve seal bad, rust and other defects, pneumatic soft sealing gate valve using elastic disc produce elastic deformation compensation effect to achieve good sealing effect, the pneumatic valve switch with light, reliable sealing, good elastic memory and the service life and other significant advantages. Can be widely used in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy systems such as body line used as adjustment and the closure device. But for pneumatic hard seal gate valves with pneumatic soft sealing gate valve is the main difference between what? Small make up xiangyu pneumatic valve is detailed to introduce the next!
hard seal, seal on both sides of all is the metal material or other hard materials is referred to as' hard seal. This seal sealing performance is poor, but high temperature resistance, wear resistance, good mechanical performance.
soft seal: seal on both sides of a side is the metal material, on the other side is elastic non-metallic materials known as' soft seal. This seal sealing performance is good, but not high temperature resistant, easy to wear and mechanical was lacking.
soft seal refers to seal the side is to use low hardness material, generally speaking, the soft seal USES a certain strength, hardness and heat resistance properties of non-metallic materials, sealed performance is good, can achieve zero leakage, but with poor life and adaptability to temperature.
hard seal made of metal sealing performance is relatively poor, despite the manufacturers claim to achieve zero leakage.
soft seal has the advantage of good seal performance, defect is easy ageing, wear and short service life. Hard seal service life is long, but the sealing is relatively worse than soft seal. The two seal can complement each other, in terms of sealing soft seal is relatively good, but now hard seal sealing also can meet the corresponding requirements.
