2 Durco BX2001 Performance Plus Economy Equals Total Value The Big Max BX2001 high performance valve is a superior quality, ANSI Class 150 valve available in standard PFA Teflon and optional UHMWPE, fire sealed and TriFlex metal seated versions. Offered in 2 in (50 mm through 36 in (900 mm sizes and in both wafer and lug body designs, all are available with a wide variety of packing options to meet your routine or most rigid service Total Quality BX2001 effectively contains fugitive process media emissions regulated by the federal Clean Air Act, including chlorine, hydrofluoric acid and anhydrous HCl. Ideal choice for precise throttling control or on-off service with lighter weight piping systems and less expensive, energy efficient actuators. Superior Features Primary stem seal plus two optional secondary seals provide triple leak protection. Retainer is locked in the valve body by a unique lock or fasteners, depending on size. Adjustable, live-loaded packing adapter option is available. Self-adjusting, self-contained, constant preload stem seal option may be specified. Low profile disc increases capacity and provides better flow control. Wide range of optional materials include: D20, DMM, DC2, DC3, DNI and DINC. PFA Teflon /Viton A energized seat provides positive, bidirectional shutoff with long cycle life on low pressure and vacuum, and high P services. (See page 5 for more information about seating. World Class Valve Performance All castings meet rigid ASTM standards. All BX2001 valves comply with ANSI B16.34, ANSI B16.5, ANSI B16.10, MSS SP68, MSS SP61, API 598, API 607, API 609, and ISO All PFA Teflon seated valves and optional UHMWPE seated valves are tested in accordance with ANSI B and MSS SP61. No through or external leaks are allowed, thereby exceeding the shutoff requirements of ANSI/FCI 70-2 for all classes. All TriFlex metal seated valves are tested to ANSI/FCI 70-2 Class VI leakage rates. All valves available in ANSI Class 150 DIN PN 16 or DIN PN 20 drilling. Unique, high strength Gibb pin positively locks valve shaft to the disc. Gibb pin is used on 2 in (50 mm through 12 in (300 mm sizes. Blow-out proof stem design guards against catastrophic leakage and stem blow-out in the event of shaft failure. Flats or double D on shaft provide positive indication of valve position and simplified adaption to automatic actuation. Large diameter, one-piece high strength shaft reduces deflection for positive, repeatable shutoff at higher P than similar valves. Independent packing set adjustment prevents stem seal emissions. Wide choice of packing materials including adjustable and selfadjusting live-loaded with leak detection port or purge fittings for lethal, toxic or sub zero services. Positioning holes on wafer body allow easy installation and proper alignment between flanges. Poly Lube bearings (Teflon and filament wound fiberglass or optional Riload bearings both offer low torque and high cycle life. 360 O-ring squarely and securely locks retainer ring into valve body. Full coverage retainer ring allows complete compatibility with all gaskets and no interruption in the sealing surface. Integral cast overtravel disc stop is designed into the casting, not welded in place as an afterthought. Blind bottom shaft hole eliminates potential leak point. Compact construction allows installation in tight spaces. Economical, simplified field repair due to minimum parts, interchangeable disc and shaft, and simple assembly procedures. requirements. All carbon steel bodies electrostatic epoxy coated for enhanced corrosion protection. 2 BX2001 features a double offset disc which creates an eccentric seating action. This action eliminates seat wear, reduces opening torque when seat is upstream and allows disc to cam into seat for tight shutoff.

3 BX2001 Stuffing Box Packing Options BX2001 Seat Design Options Flowserve offers a wide variety of packing options to most cost-effectively suit your service requirements. UHMWPE Seats For Abrasive Services BX valves with ultra high molecular weight polyethylene (UHMWPE seats will provide long-lasting performance in erosive/abrasive services while also offering limited corrosion resistance. UHMWPE seats are rated for services to 200 F (93 C. UHMWPE Seat Standard, single PTFE cup and cone. e: All lantern ring packings on this page and page 5 are illustrated with two optional 1 in (3 mm NPT purge connections. One 1 in (3 mm bleed or injection port is also available. Double PTFE cup and cone with lantern ring for leakage monitoring. Live loaded, double PTFE cup and cone with lantern ring (adjustable. Live loaded, single PTFE cup and cone (adjustable. Triple seal, single PTFE cup and cone (self-adjusting/self contained. 2 in (50 mm 12 in (300 mm only Fire Sealed Valves Low Priced Valve Security The fire sealed version BX2001 meets API 607 Requirements. If a fire destroys the PFA Teflon/Viton O-ring energized primary seat, the Inconel X750 metal backup seat activates to provide positive sealing. Shaft packing and gaskets are made of Grafoil to prevent both through and external leaking. Shaft packing performance is enhanced by the Durco rocker arm adjuster. e: The use of lug body style is recommended for fire sealed valves. Stuffing Box Packing Options Standard Fire Sealed, Single Grafoil Fire Sealed, Double Grafoil With Lantern Ring Primary seat before fire 4 Triple Super Seal For Toxic Services This ultimate protection package features compression springs which keep constant preload on the double PTFE cup and cone stem packing. Lantern ring allows use of leak detection and monitoring devices with optional 1 in (3 mm NPT connections. This self-adjusting, self contained sealing system applies the best available environmental protection technology. Available through 12 in (300 mm size. TriFlex Metal Seated Valves Uniquely Designed for Reliable, Tight Shut-off Performance The Durco TriFlex Big Max is a truly unique dynamically sealed metal-to-metal seated valve. Taking maximum advantage of specialty high temperature alloys, TriFlex utilizes the sleeve and coil action of three individual springs plus the energizing force of process fluid pressure to provide outstanding shutoff service. These highly resilient springs also offer excellent corrosion and abrasion resistance for extended service life. Exceptional Cycling Performance Reasonable Seating/Unseating Torque Inherently Fire-Safe by Design Bi-Directional Seating Fluid Pressure With Seat Upstream Metal seat after fire Available Up To 1000 F (538 C Testing to ANSI/FCI 70-2 Class VI shut off Fluid Pressure With Seat Downstream
