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
Fixed Ball Valve
①Sealing reliability Reliable bidirectional sealing Sealing conforms to the requirement of API 598/ASME B16.104 class Ⅵ
②Special root for high temperature and high pressure ·high strength, high stability, the sealing at valve stem that ensure the long life ·conform to the fireproofing requirements of API 6FA ·external leakage conforms to EPA standard
③Multiplicate valve seat structures design ·the optimized design of the spring loaded structure to ensure the good sealing under low pressure difference and excellent high temperature performance. ·automatically compensate the sealing face wear ·hard sealing system structure and unique hard sealing material that aim at working conditions
④Automatic pressure relief design in middle chamber When the medium pressure in valve cavity increased abnormally, the design of concession valve seat can guarantee the cavity pressure to relief automatically through pushing the valve seat, ensure the safety of valve.
⑤Advanced technique of ball and valve seat surface hardening treatment The company performed in‐depth research for material that aim at hard sealing system damage mechanism, after a large number of tests, 20 unique hard sealing materials have been standardized, select the material according to different conditions, has wear resistance, corrosion resistance, high combining ability, low porosity and lower friction performance.
