Leave the valve slightly opened.? Remove bolts 28 and remove gear box 25.? Pull the stem 7 out of the body.? Push disc 2 together with seat 3 out of the body 1. Therefore use a lever to pull the seat and the disc through the body.? Turn the disc in full opened position. Press the seat slightly and remove disc 2 from seat 3.? Remove o-rings 4 and 5 with a suitable tool.Assembly of the valve? The valve assembly is to be performed in reverse or-der to the disassembly.? Before the assembly all parts have to be checked for damages.? All parts have to be clean.Maintenance and installation? If necessary, a silicone free lubricant can be applied to the o-rings.? Set the o-rings in the disc’s notches and set the disc in the seat.? Setting the seat together with the disc in the body, the disc must be in half opened position.? The stem is to be mounted in a way that its top mark complies with the disc position.? After assembly carry out a pressure test acc. to DIN EN 12266-1.Notes for correct installation? Because of the full cover seat additional flange gaskets are not necessary.? Install the valve without invoking material stress, there-fore be aware of flange face parallelism, axial misalign-ment and valve length.? For use with media containing solids or sediments the valve should be installed with the stem in horizontal position and the disc opening in flow direction.? Depending on the size chamfered stub flanges accor-ding to T2-11 have to be used. Gear versionButterfly valve type 56 and type 753812825674525416
