Description for Abo Valve Double offset butterfly valves Series 2E

ABO's Series 2E double eccentricity butterfly valves are designed for operation in very harsh environments that require high safety, trouble-free operation and minimal maintenance. The double eccentricity design ensures safe operation and tightness even with sudden changes in temperature or pressure. The purpose of the second eccentricity is to quickly relieve the seal of compression between the closing disc and the valve seat, which extends seal life and reduces torques. As the flapper closes, the rotational motion of the disc changes to linear, effectively pushing the disc into the seal space. This design also prevents unwanted accumulation of e.g. suspended solids in contact between the disc and the sealing surfaces.NOMINAL SIZE:DN50 – DN600BODY TYPE:WAFER type with through holesLUG type with threaded holesDouble-flange body type with through holes        WORKING PRESSURE:16 bar / 25 bar / 40 bar / 50 barFLANGE CONNECTION:PN6 / PN10 / PN16 / PN25 / PN40 / Class 150 / Class 300WORKING TEMPERATURE:-55 °C / +325 °C *) *larger operating temperature range according to the material design of the damperWORKING MEDIA:Waste and supply water, Potable water, Hot industrial water, Petroleum products, Fuel, Oil, Oil derivatives, Pulp, Paper stock, Gas, Steam, Condensate, Air, BitumenTIGHTNESS:Class A **)**) metal-to-metal seal class CBODY MATERIAL:Low carbon steel 1.1156 (A352 LCC)Carbon steel 1.0625 (A216 WCB)Stainless steel 1.4408 (A351 CF8M)ATEX version and TA-luft seal on request
