1 heavy duty industrial resilient seated butterfly valve FETURES GENERL PPLICTION Water, air, dry bulk conveying etc. These valves are for any service where a drop-tight shut-off with maximum flow area is required. TECHNICL DT Sizes: DN Pressure: 16 bar DN bar DN Reinforced seat: 16 bar DN End of line: 10 bar DN bar DN Reinforced seat: 10 bar DN Vacuum service: 0.4 bar Temperature: -28 C to +160 C Flange accommodation: PN 6/10/16 SME 125/150 JIS 10K BS Table E S4087 PN 16 S2129 Table E Wafer and lugged body design with face-to-face dimension, according to EN 558 Series 20 and PI 609. Designed according to EN 593 and PI 609. The seat is field replaceable and fully isolates the body and shaft from the flow. Primary shaft sealing exceeds the pressure rating of the valve and prevents leakage through shaft area to atmosphere. secondary shaft sealing provides back-up safety. molded-in O-ring in the seat for flange sealing eliminates the need for gaskets. Shaft seals prevent moisture penetrating into the shaft area. The two piece shaft allows for a thin disc and provides minimal obstruction to flow (up to DN 300). Rounded polished disc edge gives full concentric sealing, lower torques, longer seat life and drop-tight shut-off. Body locating holes allow ease of installation and centering between the flanges. Extended body neck allows for pipe insulation. ctuator flange according to ISO Top and bottom shaft bearings for optimized support and minimum friction and decreased torque. Top bushing absorbs actuator side thrust loads. ll valves comply to Pressure Equipment Directive (2014/68/EU) Module B + D, CE Marking. vailable approvals: NSF/NSI 61, CS, KIW, WRS, DVGW-G, BS, CU-TR. Sizes DN 20 up to DN 40 might deviate from the above mentioned features. Please contact factory. Emerson.com/FinalControl 2017 Emerson. ll Rights Reserved. VCTDS EN 18/04
