1 Type series booklet /8-10 KE ELASTOMER Centred disc butterfly valve with elastomer liner Wafer type body Full -lug type body DN 40 to 300 Allowable pressure PS 10 bar Design in accordance with EN 593 and ISO Applications Moderately corrosive and/or abrasive fluids encountered in the chemical industry and in the manufacturing of powder products. Working conditions Temperature range: from --20 Cmin.upto+150 Cmax. The working temperature depends on the media and the nature of the elastomer used. Allowable pressure (PS): 10 bar at room temperature. Vacuum service down to 0.3 bar absolute. Maximum fluid velocity, under allowable pressure PS: -- 5 m/s for clean liquids, m/s for clean gases. Materials See page 2. Design Two--piece body: -- wafer type (type 1): DN 40 to 300, -- full--lug type with raised faces (type 4): DN 40 to 300. Extended neck allowing insulation. Shaft with anti blow--out device. Ground cable connection. Possible downstream dismantling and end of line for bodies type 4. Face--to--face in accordance with EN series 20, ISO 5752 series 20, API 609 table 1 standards. Mounting plate meeting ISO 5211 standard. Marking in accordance with EN 19 standard.

2 Materials Body Spheroidal graphite cast iron JS 1025 One--piece shaft/disc overmoulded in PFA Core in stainless steel (13 % Cr) overmoulded in PFA Shaft (version with metallic disc) Stainless steel (17--4) Disc Stainless steel Polished stainless steel NORIHARD white iron Liner E.P.D.M. Heat E.P.D.M. VITON Carboxylated nitrile HYPALON (in option) KSB Code 3l KSB Code 6k F KSB Code 6e KSB Code 6 6i 5h KSB Code XA XV VA CB Y Sealing principles Shaft passage sealing: obtained by the contact pressure between the spherically machined disc and the spherically moulded hub areas of the elastomer liner. The compression of the liner collar between the shaft and the body ensures a perfect leak-- tightness Flange sealing: achieved by the compression of the liner faces between the valve body and the flanges. Upstream/downstream sealing: obtained by the compression of the liner between the valve body and the spherically machined disc edge. 2
