3 The shape of the disc provides lower torque and prolongs the life span of the valvePTFE/graphite bearing ensures perfect turning and centric positioning of the stem. The bearing is placed inside the discSeat vulcanized to a phenol back-up ring which makes seat replacement very easy. The tolerances assure 100% tightness at full differential pres-sure. The valve is ideal for vacuum applications and mounting between flanges is easily doneSquare stem - angled at 45 . Material is AISI 420 or AISI 431 to insure high torque transmission with-out damage. Smooth finish surfacePTFE bearing ensures perfect turning and centric positioning of the stem. The sleeve bearing pro-vides excellent support if actuators are used for automation purposesHigh quality GGG40 steel body with standard ISO 5211 mounting is coated according to ISO 12944 C3 industrial standard with 3 layer Epoxy/Epoxy/PUR 160 Both Wafer and LUG has fully changeable liner con-struction.

AExtended life spanThis Butterfly valve has a unique wave line rubber seat and a special disc shape, enhancing the life span of the valve and torqueDue to the unique wave line rubber-seat and disc shape, the Butterfly valve has a low breakaway of a kind It is the only Butterfly valve in the world constructed with a bushing inside the disc - resulting in lower torque, lower friction, 100% tight shut-off function and a very long constructionOn the Wafer type the seat is vulcanized onto a phenol back-up ring.

8 AShaft / bearingsSquare bearing ensures perfect turning and centric positioning of the sleeve bearing provides excellent support, where actuators are used for automation bottom bearingThe bottom PTFE/Graphite bearing is one of a kind - it is placed inside the disc, where it is actually there would be a bearing in the bottom of the body - which means a rotating shaft that transmits the forces put onto the disc down to the result is a displacement of the forces and this is prevented by the unique bottom bearing - giving the valve a longer and trouble-free life shafts for transmitting force are more vulnerable to excessive torsion than short ring and end coverThe V-ring provides a secondary seal which prevents leakage to the V-ring also provides a weather end cover is sealed at the bottom with a threaded end cover has an anti-dust DN40 - DN300 Wafer & Lug typeKnow-how makes the difference7B-2232-UK-09-2013-REV.
