Valves & ControlsSince valve.co.kr3
Since 1984 when we stepped into the field of butterfly valve, we have extended a range of supplyand provided advance solutions for the stringent requirements of today s process industry on thebasis of the field experience and continuous research and development.Unicom offers a complete application of butterfly valve to the power plant, district heating, gas andoil industry, chemical plant, and general service. If you have a pressure to be controlled bybutterfly valve, then you can find a solution from SDHIGH-SEALMTDBUTT WELD troChemicalRefineriesSteel &IronPlantEngineering

FSDHaving a combined function ofGTD and MTD, the FSD givesa tight shut-off at nominalpressure and temperature rating.FSD sealing system consists ofreinforced teflon and metal seat.Although FSD has double seatstructure, it requires relativelylow operating torque.FSD valve works with the metalseat when a teflon seat has beenburned out.FSD provides the more reliabilityfor steam and hot air line amongits applications.Sealing structureFire test ( 11823 )
