Key Products/TechnologiesKeyProducts/Technologies
Butterfly valves are available in metal seat and resilient seat types, with high-performance ANSI 1500LB 26-inch pneumatic control butterfly valves tested at 282bar.g. High-performance and triple offset butterfly valves feature full rubber lining for seawater applications and cryogenic testing capabilities. Check valves include swing, butterfly, dual, tilting, and nozzle check valves, optimized for fluid flow control. Damper valves, such as normal, flux control, and high-temperature types, offer solutions tailored to specific industrial requirements. The product portfolio also encompasses ball valves, aqua plug valves, gate valves, and globe valves. Specialized valves like through conduit gate valves, 3-lever valves, goggle valves, slide gate valves, and PTFE lined butterfly valves are part of their custom product development. The company utilizes FEMAP with Nastran for butterfly valve design and verification, including PN40 – 114-inch FEA data analysis capabilities.Butterflyvalvesareavailableinmetalseatandresilientseattypes,withhigh-performanceANSI1500LB26-inchpneumaticcontrolbutterflyvalvestestedat282bar.g.High-performanceandtripleoffsetbutterflyvalvesfeaturefullrubberliningforseawaterapplicationsandcryogenictestingcapabilities.Checkvalvesincludeswing,butterfly,dual,tilting,andnozzlecheckvalves,optimizedforfluidflowcontrol.Dampervalves,suchasnormal,fluxcontrol,andhigh-temperaturetypes,offersolutionstailoredtospecificindustrialrequirements.Theproductportfolioalsoencompassesballvalves,aquaplugvalves,gatevalves,andglobevalves.Specializedvalveslikethroughconduitgatevalves,3-levervalves,gogglevalves,slidegatevalves,andPTFElinedbutterflyvalvesarepartoftheircustomproductdevelopment.ThecompanyutilizesFEMAPwithNastranforbutterflyvalvedesignandverification,includingPN40–114-inchFEAdataanalysiscapabilities.
The company ensures the supply of world-class quality products through optimized valve design, material selection, and cutting-edge coating technology. Its high-performance valves demonstrate design capabilities that meet international standards and customer specifications. The valve structure protects the body, disc, and seat from acidic fluids, with metal rings and O-rings attached to the seat exterior for leakage prevention. A variety of seat materials, including NBR, NR, VITON, EPDM, SILICON, and PTFE lining, are employed.Thecompanyensuresthesupplyofworld-classqualityproductsthroughoptimizedvalvedesign,materialselection,andcutting-edgecoatingtechnology.Itshigh-performancevalvesdemonstratedesigncapabilitiesthatmeetinternationalstandardsandcustomerspecifications.Thevalvestructureprotectsthebody,disc,andseatfromacidicfluids,withmetalringsandO-ringsattachedtotheseatexteriorforleakageprevention.Avarietyofseatmaterials,includingNBR,NR,VITON,EPDM,SILICON,andPTFElining,areemployed.
