3 Features of Welded Ball Valve Benefits International Certifications and Standards esigned to satisfy in district heating network, heat transfer piping, oil pipelines and gas industry application ong lifetime as same as the pipeline system ow running cost with Maintenancefree, no adjustment or lubrication Bidirectional valve Easy available for preinsulated construction and adopted to preinsulated singletwin piping systems esign Construction & Characteristics Onepiece welded body & endpiece ong lasting against frequent operation, impurities and chemical without body leakage. Stress analysis to withstand stresses in district heating network & natural gas pipeline network. Easy installation, no servicing, long working life with low running costs. Ball Mirror polished stainless steel ball tested spherical roundness. Floating ball with seat rings supported by dish springs remains leaktight regardless of pressure fluctuations. Trunnion ball applicable to high pressure or large size valves reduces sealing load against the fluid pressure, enhance seat lifetime with lower operational torque. Seats Rings & Seat Springs Bubble tight excellent sealing with carbonreinforced PTFE(Teflon) seats. Selflubricating capabilities without additional lubricant, resistant to corrosion, ageing and extreme temperatures. Preloaded seat springs ensure leaktight at low pressure. bsorb stem loading moments and reduce valve operational torque. Stem & Stem sealing nti blowout stem according to international standards. ccurate machining of sealing surface with Orings ensures leaktight sealing. ouble Orings ensure the stem sealing and can be replaced with the valves in fully open or fully closed position by removing the backup ring after having released all the pressure in the body cavity. Stem extension is available according to customer design requirement. Thrust Bearing & ry Bearing The PTFE thrust bearing between the stem shoulder and neck part acts as a stem seal. Stem dry bearing, metal with PTFE coating having selflubricating capabilities need no additional lubricant, reduces side thrust effect on packing and prevents stem wobbling, and low friction coefficient to reduce operational torque at pressurized cavity condition. Worm Gear Operator(Vertical & Horizontal type) Removable splined bushing to permit accurate positioning between gear drive and valve stem. Tapered roller bearings which support both axial and radial forces generated by the gearing have excellent load bearing capacity. Prelnsulated Twin Ball Valves for district heating pipeline network KMC PI twin ball valves meet the international standards and are only approved by Korea istrict Heating Corp. KMC Corporation 3
