-Disassembly of the valveAttention: Never dismantle the valve when the pipe is under pressure.? Dismantle the valve from the pipe (flanged version: remove flange bolts; true union version: remove union nut 26 (s. L1-2)).? Bring the valve in half opened position. Loosen the bonnet bolts 18 and remove the bonnet 2.? Remove gauge cover 11.? Remove o-ring 14 and name plate 12.? Turn the hand wheel 10 clockwise to the stopper, then turn it back slightly.? Turn the diaphragm 3 of 90°, pull diaphragm 3 and compressor 6 off the stem 8.? Pull joint 7 off stem 8.? Hold stopper 20 with spanner to prevent it from tur-ning and loosen screw 21 with an allen key. Unsrew the stopper from the stem.? Remove the retaining c-type ring 13 with the circlip-pliers from sleeve 9.? Pull the hand wheel 10 off the sleeve 9.? Remove the thrust rings 16 + 17 and o-ring 14 from the bonnet.Assembly of the valve? The valve assembly ist to be performed in reverse order to the disassembly.? Before the assembly all parts have to be checked for damages.? All parts have to be clean.? To mount the diaphragm, put the joint 7 on the stem 8. The slot must be in 90° position to the axle between the guiding slots in the inner side of bon-net 2.? The diaphragm flag must be positioned in the clearances of body and bonnet.Stopper adjustment? Close the valve by turning the hand wheel 10 clo-ckwise by hand. Check the diaphragm`s position in the valve body: In closed position it must completely cover the nose piece of the body.? Tighten the stopper 20 with medium force and hold it with a spanner to prevent it from turning. Tighten screw 21 with an allen key.Required tools: DN 65 80 100 Allen key - - - Spanner 2x17 2x17; 19 2x17; 24 Circlip-pliers 19-60 19-60 19-60 Pin driver 5 5 5? Unscrew gauge cover 11 counter-clockwise.? Drive compressor pin 89 out of compressor 6, so that the compressor can be removed from stem 8.? Remove group of parts 20, consisting of stopper, red washer, nut and blank washer, from the stem. Loosen the nut first.? To mount the diaphragm, put the compressor 6 on the stem 8. Drive pin 89 into compressor 6 so that it is flush with it.? Mount group of parts 20: put the blank washer on stem 8, put the red washer between the stopper and the nut and lock it by tightening the nut.Maintenance and installationDN 15-50 DN 65-100Diaphragm valve type 14alike DN 15-50alike DN 15-50alike DN 15-50alike DN 15-5004/2012L1 – 8Errors and omissions exceptedPlastic valvesDN 15 up to DN 50Notes for correct installation? The valve must be installed stress-free in the pipe (plane parallelism, axial, overall length).? Flange version: Tighten the connecting screws evenly and crosswise (observe tightening torques). In general, use washers for the nuts and bolts in plastic flanges.? Spigot end and socket end version: Connect valve and pipe according to the relevant specifications for gluing and welding.all DNDN 65 up to DN 10011141310162120121576891718243118144a318182179894896 181211201314101615Diaphragm valve type 14Assembly and maintenance procedure
