Full welded ball valve solution

Published:2014-04-24 Hits:

    WENBAO VALVE manufacturing of the fully welded ball valves,  the valves are composed of three independent forgings by welding into an integral,to ensure that the ball valve without leakage under the permitted working conditions .Products are mainly used in: natural gas, oil, water and other medium, suitable for district heating, city gas, petrochemical, steel, shipbuilding, metallurgy, power stations,etc. WENBAO valve supply perfect quality assurance and after-sales service for you to purchase WENBAO series products.

Design features

Valve body material is adopted international standards low carbon steel and low carbon steel pipes,   using advanced automatic welding machine for welding, pipeline weld using NDT testing.
1.The connection pipe is adopted forging one-piece forming,make the performance of the disc spring can be still normally used under-200℃, also can be designed a variety of connection modes according to the requirements of users.
2.The stem is chosen high-performance stainless steel material,with good corrosion resistance; blow-out proof design, use more securely; sealing material is fluorine rubber (FPM), carbide teflon (PTFE+C) or PEEK,with high strength, high temperature and high pressure resistance, good corrosion resistance, long service life, etc.
3.The ball is chosen high performance stainless steel, after the completion of the processing, then detected by the precision roundness detector( RONDCOM30C) which origin from Tokyo-Japan, with very high precision.

    Technical Parameter
    Nominal diameter:DN15~DN1200 (1/2"~48"),
    Nominal pressure:PN16~PN100(Class150~Class600)
    Applicable temperature:-20℃~200℃
    Body material:Carbon Steel、Stainless Steel
    Ball material:SS304, SS316
    Stem material:2Cr13、SS304、SS316
    Connection type:Butt weld, Flanged
    Operating  mode:Lever、W o r m gear(vertical/horizontal)、Pneumatic, Electric,etc.
    Executive standard:GB/T12237-2007, API 6D,ASME B 16.34、ISO9001、KC、 TS.

    1 Fully Welded Ball Valve:
      Body material:Carbon Steel
      Ball material:SUS 304
      Stem material:2Cr13, 304
      Nominal pressure:PN25~Pn40
      Applicable temperature:-20℃~200℃
      Size:DN15~DN125 manual operate:DN150~DN300 gear operate
Fully welded ball valve has the structure of sealing in both directions, the seat is chosen carbide teflon seal ring, high intensity, good self-lubrication,small friction coefficient;
The disc spring behind the seat has compensation function to ensure that the seat sealing surface and spherical surface fit closely, won't leakage in the specified pressure and temperature range. Connection type have butt welding and flanged .Applicable medium: water, gas, steam, oil.
  2 Fully Welded Trunnion Mounted Ball Valve
    Body material:Carbon steel
      Ball material:SUS 304
      Stem materia:2Cr13、SS304
      Nominal pressure:PN16~PN40
    Applicable temperature:-20℃~200℃
  
DN350~DN1200 Fully welded ball valves are trunnion mounted ball structure, up and down the shaft of the ball is equipped with composite bearing,further to reduce the operation torque at the time of opening and closing of the valve, when get the medium pressure, floating seat will generate shift to make the sealing face close to the spherical surface, when low pressure, rely on the spiral spring behind the seat providing necessary thrust to ensure high seal. Can also be designed long body, long stem,full bore,reduced bore,etc. Applicable medium: water, gas, steam, oil.
  
      Body material:Carbon steel
      Ball material:SUS 304
      Stem material:2Cr13, 304
      Nominal pressure:300LB~1500LB
      Applicable temperature:-20℃~200℃
Directly buried fully welded ball valve can be directly buried in the ground,not need to build big valve well and underground control center, simply well only using a Thandle transmission operation on the ground,to eliminate the safety hidden trouble of going into the ground control
  center .Applicable medium: water, gas, steam, oil.

  4 High Pressure Fully Welded Ball Valve
  Body material:Carbon steel
  Ball material:SUS 304
  Stem material:2Cr13、304
  Nominal pressure:300LB~1500LB
  Applicable temperature:-20℃~200℃
  Design standard:API6D, API 608
  
Body is composed of three independent forgings by welding into an integral, the body size is chosen comply with relevant standards intensity and rigid requirements; the seat sealing can be chosen teflon and carbide teflon according to different situation, when low pressure,rely on the spiral spring behind the seat providing necessary thrust to ensure high sealing, in addition, can also inject sealant to auxiliary sealing system. Stem has a blow-out proof structure design,won’t fracture and blowout if improper operation,have independent seal, at the same time can also inject sealant to auxiliary sealing systems; The valves have fire safe, anti-static design. Applicable medium: water, gas,steam, oil.
