Epoxy Coated Cast Iron Lever Operated Butterfly Valve

Model NO.: SDV035 Connection Form: Wafer Seal Form: Metal or Rubber Work Pressure: Low Pressure (Pn<1.6mpa) Material of Seal Surface: Soft Sealed Application: Industrial Usage, Household Usage Trademark: SDK Origin: China Driving Mode: Manual Structure: Centre Sealing Valve Stem: Normal Working Temperature: Normal Temperature (-40°C
Feature
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.
4.Weight
    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 
    save cost of piping system.
5.Bubble Tight
    Butterfly valve with resilient seat design can be bubble tight as compared to metal seated gate
    or globe valves.
6.Easy of operation
   Butterfly valve offer 90-degree open to close.
7. Butterfly Valves is approximate 35-40% cost of a same size gate valve. Also low 
    installed cost than gate valve.
8.Maintenance
    Properly installed butterfly valves are self cleaning and are less susceptible to failure due to 
    trash material in pipe.
9.Delivery Time:25 days after order conformed.
