engineering,ship building,water supply and sewage,metallurgy,energy engineering as well as light
1. Long service life with reliable seal and without frequent main tenance
2. Pressure loss
     Too much pressure loss will bring increased cost of correlative energy
      Butterfly valve have flow characteristics three times better than globe valve,and about 75%
      of a same size gate valve
3. Multi-Function
    Butterfly valve can be used for on/off service and throttling,They are superior in Multi-function
    as compared to gate or globe valves.Butterfly valve can be widely used in chemical field due
    to trim options and choice of elastomeric liner.
    Butterfly valve have feature of light in weight and small in size,for example, weight and size of 
    a 10'' butterfly valve are 1/9 and 1/6 of a 10'' gate valve.So butterfly valve is easy to install and
