Three segment type soft sealing ball valve, three segment type hard seal ball valve.

Path: 1/2" - 32"

Pressure: 150Lb ~ 2500Lb

Temperature: -196 C~ 650 C

Medium: water, steam, oil, natural gas, coal gas, acid and alkali salt, methanol, ethylene, urea, etc.

Material: carbon steel, chrome molybdenum steel, austenitic stainless steel, dual phase steel, alloy 20

Product features: the latest computer technology (CAE, CFD) used in a full range of products; all CNC machine tools or machining center processing; stem blowout out of the body; soft seal fire protection design. High pressure valve all forging.

Optional structure feature Double close and discharge function design Adopts valve seat sealing before ball, two valve seats can independently cut off the medium of import and export ends, to achieve double blocking function. When the ball valve closed, even if both ends of valve inlet and outlet have pressure, the middle cavity and channels of both sides can be blocked each other, the remained medium in the cavity can be discharged through the discharge valve.

Self cleaning structure design For the slurry contains slag, thinner with strong adhesion, powder, large granular material, the unique design of scraper seat shall prevent the medium bonding on the sealing face, ensure the sealing reliability, prolong the life of valve. Extended valve stem design        According to the working conditions such as high temperature, high pressure or buried, the valve stem can be extended.     When working condition＜200℃, PTEE packing can be selected.     Structure design of shrinkage     Discharge, blow and sweep design
