KEYSTONE SERIES GR RESILIENT SEATED BUTTERFLY VALVES …

1 KEYSTONE SERIES GR RESILIENT SEATED BUTTERFLY VALVESGRW/GRL (ISO) 2021 Emerson. All Rights heavy duty industrial RESILIENT SEATED BUTTERFLY valveFEATURES Wafer and lugged body design with face-to-face dimension, according to EN 558 SERIES 20 and API 609. Designed according to EN 593 and API 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. A secondary shaft sealing provides back-up safety. A 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).

2 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. Actuator flange according to ISO 5211. Top and bottom shaft bearings for optimized support and minimum friction and decreased torque. Top bushing absorbs actuator side thrust loads. All VALVES comply to Pressure Equipment Directive (2014/68/EU) Module B + D, CE Marking. Available approvals: NSF/ANSI 61, ACS, KIWA, WRAS, DVGW-G, ABS, CU-TR. Sizes DN 20 up to DN 40 might deviate from the above mentioned features. Please contact APPLICATIONW ater, air, dry bulk conveying etc. These VALVES are for any service where a drop-tight shut-off with maximum flow area is DATAS izes: DN 20 - 900 Pressure: 16 bar DN 20 - 300 10 bar DN 350 - 900 Reinforced seat: 16 bar DN 350 - 600 End of line: 10 bar DN 20 - 300 6 bar DN 350 - 900 Reinforced seat: 10 bar DN 350 - 600 Vacuum service: barTemperature: -28 C to 160 CFlange accommodation.
