4 Butterfly Valve Soft Seated Overall benefits Type 2230 Wafer Dimensions DN50 - DN00 Long service The butterfly valves has an unique wave line rubber seat and a special shape of the disc, which enchances the life time of the sealing and the valve Reduced torque The butterfly valves has a low torque, because of its unique wave line rubber seat and shape of its disc Butterfly Valve Soft Seated Type 2240 Lug Perfect turning and centric positioning The butterfly valves has a PTFE/graphite bushing, which ensures perfect turning and centric positioning of the stem Dimensions DN50 - DN00 One of a kind It is the only butterfly valve in the world, which is constructed with a bushing inside the disc - resulting in lower torque, lower friction, 100% tight shut-off function and a very long service. Seat construction The seat is vulcanized onto a phenolic back-up ring. The construction makes it possible to use the valve down to full vacuum - or at 1 bars differential pressure - with 100% buble-tight shut-off function as a result Butterfly Valve Soft Seated Type 2400 Double flanged Dimensions DN50 - DN2000 Troubless mounting Multi-standard alignment holes: DN50-DN300 suitable for flange of EN1092 PN, PN10,PN1, ANSI 125/150, and BS10 TABLE D, TABLE E Fully PN1 rated The butterfly valves can easily operate up to PN1 in all dimensions. 3 Valves with a difference

Chemical Food and beverage Pharmaceutical Pulp and paper Mining and power Vacuum HVAC industries Stem square according to valve torque Stem square according to valve torque Stainless steel disc ensures blow-out proof stem V-type ring, provides a weather seal PTFE/graphite bearing ensures perfect turning and centric positioning of the stem. The sleeve bearing provides excellent support if actuators are used for automation purposes V-type ring provides a secondary sealing, preventing leakage from the stem Multi-standard alignment holes: DN50 - DN300 suitable for flange of EN1092 PN, PN10, PN1, ANSI 125/150 and BS10 TABLE D, TABLE E. Dimensions above DN300 according to requirements Unique seat wave line rubber seat reduces the torque of the valve and enhances the life time of the sealing Disc with two-piece shaft construction enhance the flow capacity of the valve. The shape of the disc provides lower torque and prolonges the life span of the valve Seat vulcanized to a phenolic backup ring which makes seat replacement very easy. The tolerances assures 100% tightness at full differential pressure. The valve is ideal for vacuum applications and mounting between flanges is easily done PTFE/graphite bearing ensures perfect turning and centric positioning of the stem O-type antidust ring V-type ring provides a secondary sealing, preventing leakage from the stem Valves with a difference 4

7 Shaft / bearings Construction Steam square according to valve torque PTFE/graphite bearing ensures perfect turning and centric positioning of the stem The sleeve bearing provides excellent support, where actuators are used for automation purposes Unique bottom bearing Construction The bottom bearing is one of a kind - it is placed inside the disc, where it is really needed Normally you have a bearing in the bottom of the body - meaning that you have a rotating shaft that transmits the forces put on to the disc down to the bearing This gives you an displacement of the forces which the unique bottom bearing prevents - giving the valves a longer and more troubleless life span The longer a shaft for transmitting the forces is, the higher the chances for excessive wear are U-type ring and end cover Construction The U-type ring provides a secondary sealing which prevents leakage from the stem The U-type ring also provides a weather-seal The end cover is sealed at the bottom with a threaded plug The end cover has an O-type anti-dust ring Valves with a difference

19 Installation guide for Butterfly Valves In general Check that the specifications on the identification plate, meets the requirements regarding pressure, temperature and media. The piping must have a straight line and the flanges has to be parallel. Furthermore there must be a distance between the flanges, corresponding to the face-to-face dimensions of the butterfly valve. The butterfly valve can be mounted in any direction. However if there is a lot of dirt particles on the bottom of the pipe, it will be suitable to mount the stem of the butterfly valve horizontally. This will protect the pivot point of the disc. Before commissioning, the installation has to be rinsed for dirt and remnants of welding material, to avoid damage on the liner. During the rinsing procedure, the butterfly valve has to be positioned as open and may not be operated, before the rinsing has been completed. Welding operation may not be performed nearby the butterfly valve, as welding drops can damage the liner. Do not use flanged packings or other packing materials. The liner works as sealing to the atmosphere. Where vacuum, high flow rate or water hammering can occur, flanges without a loose collar should be used, to obtain the best conditions. Carefully place the butterfly alve between the flanges, with the disc in closed position Check that the flange covers the area of the liner. Afterwards tightend the bolt on the flange by hand Carefully open and close the valve to check that the disc centralizes and the disc does not touch the flange. With the disc in open position, tighten crosswise with a wrench. As the butterfly valves are equiped with the unique wave shaped liner, the operation of the valves, either free stem, handle or gear operated, has to follow the guidelines as shown bellow. A small triangular shaped figure is placed on the liner - this triangle indicates which way the disc has to enter the liner. Generally spoken the disc has to rotate clockwise - CW - in order to have the lowest possible torque - and thus the longest possible life time. Turn disc CW towards arrow to close Though the valves are constructed to work as shown to the left, counter clockwise rotation - CCW - can be applied without problems - IF you take into consideration that the torque in this case will increase. Note: always add a safety factor ( x 1,25 ) in regards to torque when applying actuators. Turn CW to close Valves with a difference 18
