3 1 Te Double Eccetric Desig Priciple It effects frictiofree cotact betwee body ad seat because te rotatio axis (stem) of te valve disc as a double offset from te ceter equal to dimesios of A ad B (See sketc). Because of te double offset a cam effect is produced wic prevets wear of te seal surface, decreases seatig torque ad offers loger service life ad easy operatio.
