The characteristics of Top entry eccentricity ball valve are as followings:
1.Seal valve( valve disc ,seat)—double metal ,can reach the purpose of metal sealing of metal ball, fire safe and anti-explosion.
2.Tight sealing, the valve disc and seat are contacted by ball, face and line to realize its seal, by tric-eccentric to realize zero leakage.
3.The seal valve keep the allowance, if attrition is found when the valve was used a long time, it’ll be still possible to realize the reliable sealing ,lengthen the using life by relaxing the limit bolt beside the handwheel and turn it little when close,
4.The valve can keep being used by screwing the clamp cover, adjusting or replacing the seat, to avoid scraping when the valves fail to be sealed.
We classify the eccentricity ball valve by function: Universal valve, line valve, special service valve for slurry, special service valve for gas, special service valve for oil and Chemistry, special service valve for powder-coal ejection. There’re three drive ways: hand wheel, pneumatic and electric. Eight pressure grade(PN0.25~10.0MPA),hundreds of eccentricity ball valve products. It’s the replacement of gate valve, glove valve, Y-type valve and ball valve in Oil, Chemistry, Metallurgy, Electric power, Gas industry.
Industry Scope
General Valve: Rational design, compact structure, with a circulation of small resistance, good sealing, easy operation and flexible, in particular, are used in low-pressure pipeline network of media, such as water, sewage, steam, pulp and other media. It can make up electric, pneumatic device, can realize remote automation. (Water, steam, sewage, paper pulp, slurry and other non-corrosive medium)
Pulverized coal injection special: Used to control dust gases, particles such as pulverized coal injection fluid solid conveying the ideal equipment, widely used in metallurgy, mineral processing, electricity and other production processes blast furnace pulverized coal injection, milling systems and dust collecting system in a variety of pipeline control. It uses straight-through structure, flow unobstructed, does not appear to plug fouling phenomenon, Sealing with Co-Cr-W alloy material, through a special heat treatment, valve anti-erosion wear resistance, while eccentric spherical valve with automatic compensation for the performance of , through the worm gear on the adjustment bolt, so that a certain degree of wear and tear Sealing circumstances, can achieve the re-sealing effect. (Dust gas, particle-fluid)
Petrochemical Special: For the petrochemical industry, the use of high pressure, high temperatures, filled with flammable, explosive, corrosive generally weak base weak acid medium, with good sealing, corrosion resistance, lightweight hoist that can automatically cut valve surface scaling characteristics of materials suitable for crude oil, heavy oil and other media, transportation and oil cracking, food-production process. (Oil, gas, gas, water, etc.)
Blast furnace gas, gas-specific: Sealing with Cr-Mn-Si hard alloy, refractory explosion-proof anti-static, anti-high temperature seal pair 560 ℃, its anti-corrosion and anti-bite capabilities are sealed stainless steel 6 times more than vice, especially suitable for In the gas, coke oven gas, water, gas, liquefied petroleum gas, natural gas pipeline and compression station to use the door. (Blast furnace gas, natural gas, dust-laden gases, etc.)
Slurry mixed with fluid-specific: transport easy precipitation fouling, crystallization of the solution, slurry, slurry ash and other process in the two mixed fluid medium ideal process valves can break off when the barriers to a smooth closing Filthes . Its novel structure, unique design, highly efficient energy-saving, good wear resistance, sealing and reliable, easy operation, open and close rapidly, and long service life. (Craft slurry slurry containing ash and other particulate matter transport)
Dedicated pipeline: part of straight-through half ball valve, no reducing, body channels and pipelines to connect the pipeline into a straight pipe interlinked, cross-sectional area are equal , the resistance is less than reducing, just turn 90°,it can reach full open&close and will be convenient for controlling the long-distance pipeline transporting.(Pulverized coal injection and gas transportation).
