E3 Gate valve | Combi valves Overview Design features • Resilient seated gate valve according to EN 1171, EN 1074-1 and EN 1074-2 with smooth, straight-through bore DN 50 – 200 Spindle bearing with sliding disks • Double bayonet O-ring carrier is connecting the spindle to the bonnet, allowing a fully encased, uniform epoxy powder coated bonnet for further improved corrosion protection • Wedge guide made of wear resistant POM material in load optimized design minimizes attrition and ensures lowest torque actuation • Wedge is flexible and fully linked in vulcanized elastomer to the wedge nut. This snug fit dampens vibration during opening and closing of the wedge • Wedge nut has a long thread length allowing significantly higher torques than the standard before breaking • O-rings, lip-seals mounted in the bonnet are replaceable under operating pressure • Extended edge protection to avoid damages during transport, storage and assembly • Sliding disks and ball bearing assure low friction performance of the spindle DN 250 – 600 Spindle bearing with ball bearing and additional sliding disks • 100% suitable for buried installations 21 Material | Technical features 1,2 Body (1), bonnet (2), centering flange (16) made of ductile iron, 16 epoxy powder coated inside and out 3 Wedge made of ductile iron (DN 50 made of dezincificationresistant brass) with vulcanized elastomer all-over 4 Wedge guide made of wear-resistant plastic 5 Wedge nut made of dezincification-resistant brass 6 Duplex stainless steel spindle with rolled thread and flat-rolled anti-friction surface 7 O-ring carrier made of brass, DN 50 – 200 with double bayonet 8 O-rings made of elastomer 9 Wiper ring made of PE 10 Bonnet gasket made of elastomer 11 Allen screws made of stainless steel, encased into the body with interlacing gasket and sealing compounds, ensuring full corrosion protection 12 Extended edge protection made of PE 13 Spindle bearing made of dezincification resistant brass 14 Sliding disks made of POM 15 Safety screw made of stainless steel 17 Centering flange gasket made of elastomer 18 Axial ball bearing permanently lubricated 19 Centering ring made of POM 20 Lip seals made of elastomer 21 Wiper ring made of elastomer
