BFV-2B DESIGN FEATURES 2-2 CONTINUED (A) Body One-piece wafer (Series ) or full lug (Series 2) with flange locating holes (Series ) or tapped lugs (Series 2) conforming to A.N.S.I. 2/ drillings. Face to face conforms to MSS-SP-67 for universal interchangeability. Extended neck design allows for a minimum or 2 ( cm) of piping insulation. (B) Actuator Mounting Flange Designed to conform to universal standard I.S.O. 2 for direct mounting of compatible manual or power actuation equipment. (C) Stem Seal The double U cup seal design is selfadjusting and gives positive sealing in both directions to prevent external substances from entering the stem area. (B) (D) (E) (F) (C) (I) (A) (G) (H) (F) Stem Bushing The Heavy Duty acetal bushing aligns and supports the stem and absorbs side thrust associated with power actuators. (H) Disc The single piece casting is spherically machined, radiused and polished for extended seat life and bubble tight shut-off. (J) (K) (L) (D & E) Stem Retaining System The v stem is securely contained in the body by means of a stainless steel retaining washer, broached to fit over the flats on the top of the stem. The retaining washer is held in place by a high strength circlip that is fixed into a machined groove in the neck of the v. This design permits quick and easy shaft removal without the need for special tools.
BFV-2C DESIGN FEATURES 2-2 CONTINUED (G) Seat () The unique epsilon seat design has four retaining points, virtually eliminating any seat movement during the seating and un-seating of the disc. The Challenger Series 2 (full lug design) provides full rating with the down stream flange removed. (2) The double moulded-in O rings are precisely positioned to allow the flange to firmly lock the seat into the fully machined dove-tail to achieve maximum seat and sealing compression without the need for flange gaskets. This unique feature allows the use of slip-on type flanges, without de-rating the v. () Both the upper and lower shaft journals have a mouldedin double O ring secondary seal, isolating the media from the body cavity in the event of a primary seal failure. (I & J) Stem & Disc Drive Connection The close tolerance double D disc/stem connection features all of the benefits of a high strength one piece design without the disadvantages associated with designs using taper pins or disc screws, which often fail through abrasion, corrosion or fatigue. (K & L) Challenger Vs Have Primary & Secondary Sealing Features The primary seal on the Challenger v is obtained by an interference fit between the moulded flat on the seat and the hub of the disc. The secondary seal is obtained by an interference fit between the stem and the moulded-in O rings on the upper and lower shaft journals. Seating capabilities on this design do not rely on external flanging.

Note: Torque values shown are based on the amount of disc/seat interference necessary for the v to achieve the shut-off rating shown in both a wet and dry condition. Line pressure has little bearing on the seating/unseating torque. For p.s.i. service, factory under-cut discs must be used.
BFV-6 INSTALLATION INSTRUCTIONS Challenger resilient seated butterfly vs have been designed for installation between A.N.S.I. 2/ lb. flat faced or raised face flanges with an inside diameter greater than the disc chordal dimension published on the v drawings. The moulded in O rings on the face of the seat eliminate the need for flange gaskets, therefore, GASKETS MUST NOT BE USED. Refer to Bulletin no. BFV- for bolting information. () Install the v in a location that the disc will not interfere with adjacent equipment such as check vs and pumps. Ideally, the v should be installed with a distance of six pipe diameters upstream and downstream of any bends, pumps or vs. The v can be installed in any orientation, however, Challenger recommends that the v should be installed with the stem horizontal and the lower edge of the disc opening downstream on any slurry applications or applications with solid particles in the flow stream. (2) With the disc partially into the seat, carefully install the v between the flanges. Be sure to spread the flanges enough to clear the protrusion of the seat, approximately /4 to eliminate the possibility of lipping the seat. () Rotate the disc to the full open position to allow the seat to position itself in the body prior to tightening the flange bolts. Note: Challenger V recommends the removal of spring return actuators prior to installation to facilitate opening the disc. (4) Tighten the flange bolts in a cross pattern, alternating until all fasteners are snug. () After installation, carefully cycle the v manually to ensure that the disc does not interfere with the flange piping or other adjacent equipment. (6) If removed, re-install the actuator being careful to position the disc (A) closed for fail close or (B) open for fail open prior to installing the actuator. MAINTENANCE INSTRUCTIONS Challenger Butterfly Vs have been designed and manufactured to maximise life and minimise wear. All dynamic components have been lubricated prior to assembly and further lubrication is not required. Note: Vs installed in applications where the v remains stationary for long periods of time should be routinely cycled at least twice per year to reduce seat set and to clear the disc edge of any scaling. If replacement of a v component is required, refer to the assembly and disassembly instructions in Bulletin BFV-7 for v sizes 2-2 or Bulletin BFV- for v sizes 4-4.
BFV-7 ASSEMBLY/DISASSEMBLY INSTRUCTIONS VALVE SIZES 2 to 2 Assembly Instructions V Sizes 2-2 () Clamp the v body in a vice. (2) Spray the interior of the body with a silicone based lubricant to facilitate seat alignment. () Holding the seat in your hand, insert a flathead screwdriver or prybar (. times longer than the seat diameter) through the large hole from the inside out. Note that the large hole will be at the top of the v. (4) Rotate the screwdriver or bar until the seat is semi-inverted. () With the body facing you, place the seat into the body from the opposite side, bottom first. (6) Keeping the seat inverted and applying pressure, lip the seat into the dovetail from the front of the v using a small flat prying tool. Start at the bottom and work up to the midpoint, at this time you can remove the large prybar. Continue lipping the seat until it is completely inserted into the body. (7) Line up the upper and lower shaft journals using a soft hammer. () Apply a silicone based lubricant to both journals. () Into the top neck of the v, insert the shaft seal and the bushing (items & 6). () Insert the shaft into the neck of the v and tap it down until it protrudes through the upper shaft journal by approximately one inch. () Rotate the shaft until the flats are in line with the pipe. This will align the Double D drive with the disc. (2) With the broach in the disc facing down, insert the top of the disc into the seat, engaging the shaft with the top hole of the disc. () Push the bottom of the disc into the seat. (4) With the disc fully open and the v shaft aligned with the pipe, drive the shaft down using a non-metallic hammer. () Install the retaining collar (item 7) and tap it down until it clears the groove in the top of the v. (6) Install the circlip (item ). Disassembly Instructions V Sizes 2-2 () Remove actuator assembly from mounting flange. (2) Remove the circlip (item ) from the top of the v. () Remove the v stem (item 4), retaining washer (item 7), bushing (item 6) and stem seal (item ). (4) Protecting the disc edge from damage, push the disc through the seat (this is easier with the disc in the open position) () Insert a large flat screwdriver or prybar between the body and the dovetail on the seat and collapse the seat to an oval shape, remove from v body.
BFV- ASSEMBLY/DISASSEMBLY INSTRUCTIONS VALVE SIZES 4 to 4 Assembly Instructions V Sizes 4-4 () Secure the v body (preferably to a floor vice). (2) Spray the interior of the body and shaft journals with a silicone based lubricant to facilitate ease of assembly. () Slide the cartridge seat into the v body and align the top and bottom shaft journals. Note: If this is a lug body, install the seat retaining screws around the perimeter of the body (refer to drawings BFV-22 or BFV-2) (4) Insert the lower centre and lower top bushings into the shaft journal. Insert the stem seal followed by the top bushing (refer to Bulletin BFV- for details). () Apply a silicone based grease to the upper and lower flats on the seat and to the inside of the bushings and shaft seals. (6) Position the disc onto the seat with the two taper pin holes at the top and squeeze the disc into the seat until the upper and lower shaft holes are aligned (large C-clamps can facilitate this operation). (7) Insert the stem into the top of the v and using a non-metallic hammer, drive the shaft down until the taper pin holes are aligned. () Set the taper pins. () Install the bottom thrust plate complete with integral O ring seal. Disassembly Instructions V Sizes 4-4 () Remove actuator assembly from mounting flange. (2) Remove the bottom thrust plate. () Remove the disc/stem taper pins. (4) Using a round bar, drive the shaft up and out of the top of the v. () Carefully squeeze the disc out of the seat (C-clamps can facilitate this operation). (6) Press the cartridge seat out of the body. Note: If this is a lug body, remove the seat retaining screws around the perimeter of the body (refer to drawings BFV-22 or BFV-2). (7) Remove the bushings and upper stem seal.
