For superior sealing over prolonged periods, this patented seat is a proven performer. Choose softseated, firetested or hightemperature designs. 2 Tapered, staked pins prevent loosening but permit easy replacement. This positive internal overtravel stop protects both the seat and disc. For longer wear under difficult conditions, the unique retainer design protects the seat from erosion and abrasion. In addition to durable, standard Vring packing, you can also choose from optional graphite hightemperature packing or emissions control design. Crush resistant bearings are positioned for superior shaft stability. 7 The captured retainer ring is overlapped by the gasket to prevent external leakage at the flange. The screwless retainer ring eliminates potential leak paths and simplifies maintenance. (Standard for sizes 2 through. Optional on other sizes.) 9 Eccentric disc mounting minimizes seat wear and lowers operating torques. Bearings are uniquely designed and positioned for extended service life. Bonded to the interior of the stainless steel bearing is PTFE impregnated with woven fiberglass. This unique design resists crushing better than conventional fiberglass backed bearings. The stainless steel provides superior shaft support while also permitting reduced bearing thickness. This improves sealing by reducing lateral shaft movement. The PTFE's high lubricity facilitates smoother cycling. The woven fiberglass reinforces and stabilizes the PTFE, preventing coldflow. For high temperature applications, electroless nickel coated stainless steel bearings are also available. 2 Copyright Xomox Corporation 90, 0. All rights reserved. Xomox, Tufline, and Matryx are registered trademarks of the Xomox Corporation. Enhanced durability and emissions control. There are three bearings. For enhanced durability, two of the shaft bearings are positioned close to the disc (above and below). Bending stresses in the shaft are reduced. Shaft and disc deflection are minimized. The third bearing is located high on the shaft near the packing chamber. This provides greater shaft stability, assures longer packing life, and helps control emissions.

3 Tufline High Performance Butterfly valves provide superior performance in your most demanding applications. Double offset and eccentric disc mounting extends seat life, reducing maintenance costs and downtime. Seats last longer and maintenance is reduced because the eccentrically mounted disc minimizes seat deformation and wear. Reduced seat deformation. In the open position the disc is not in contact with the seat, so seat deformation cannot occur. Reduced seat wear. 7 When the Tufline valve is opened, the eccentrically mounted disc moves with a camlike action. The disc is lifted away from the seat. 2 Because moving contact between the disc and seat is virtually eliminated, the service life of the seat is greatly extended. 9 Reduced friction also means that operating torque requirements are reduced. This allows the use of smaller, more economical actuators. 0 sealing for sure shutoff. Because the disc is offset, the shaft is behind the sealing surface of the disc. When the valve is closed, there is an uninterrupted 0 seal around the full circumference of the disc.

4 Superior sealing and extended service life. The seat is axially pliant. Unlike other seals, there is no radial stretch. When the valve opens, the seat flexes axially, returning to its original compact shape. It does not "relax" into the flow path. This seat design includes two components: An outer segment of chemically inert glass reinforced PTFE. A deformationresistant, memorycore membrane. Simply superior. This seat is simple. There are no springs to break, no Orings to swell, and no metal hoops to corrode. Installation is also simple and mistakeproof. Choose softseated, fire tested, or hightemperature designs. The retainer eclipses the seat, protecting it from erosion and abrasion. Figure. s closed, with right to left flow. The axial movement of the seat in the direction of the flow produces a simple, leaktight seal. It is pressureassisted. As line pressure increases, the seal tightens. From vacuum through high pressure, tight shutoff is maintained. Figure 2. closed, with left to right flow. Bidirectional flow and shutoff are easily accommodated. The same, simple, axial movement of the seat assures a reliable seal in either direction. Figure. open, with media flowing. Even after 00,000 cycles the seat maintains a tight seal. The seat s internal pliant membrane is the memory core that precludes radial deformation. To further extend seat life, the inside diameter of the retainer ring is smaller than that of the PTFE seat. This protects the seat from erosion and abrasion.

5 Greatly improved service life is assured because the seat is axiallypliant and resists radialstretch. For enhanced emissions control, the patented* snapin retainer ring is captive. When the valve is installed in the pipeline, the flange gasket overlaps the captive retainer. This enhances the seal by preventing external leakage at the flange. There are no screws through the standard butterfly valve retainer ring. Sealing is thereby further improved because potential leak paths are eliminated. Also, there is no bottom plug. The snapin retainer ring speeds up maintenance and reduces downtime. * U.S. Patent No.,,0. An internal stop protects against seat damage from disc overtravel. To protect the seat in a butterfly valve, the positive internal stop limits overtravel. An improperly adjusted actuator could force the disc beyond the closed position. This can damage both the seat and disc of a conventional valve that has no travelstop. The shaft and disc are securely pinned for more efficient operation and ease of maintenance. During factory assembly, two stainless steel pins mechanically lock the disc and shaft. This eliminates lost motion and provides better control. The pins are staked to prevent loosening. They pass through the disc and shaft behind the sealing surface. The tapered sleeves and tapered pins make replacement of the disc or shaft economical because they do not require matched drilling.

6 Softseat sealing with firetested safety. For applications involving flammable media, the dual component seat offers both superior sealing and fire tested security. Proven Performance. Numerous test results demonstrate this valve's ability to meet or exceed the requirements of API07 Fourth Edition as well as BS SPEC 7 Part 2. The seat combines PTFE and metal sealing elements. The metal component is available in a variety of different alloys. This seat establishes both a PTFEtometal seal and a dual metaltometal seal. Graphite rope packing Metal seat component PTFE seat component Metal to metal seal PTFE to metal seal Metal to metal seal Normal operation right to left flow. This unique seat is designed for bidirectional flow control. As pressure increases, the seat shifts axially in the direction of the flow. This tightens the seat contact with the disc for sure sealing. Normal operation Left to right flow. Both the metal seat and the PTFE seat are in tight contact with the disc. As line pressure increases, the seal tightens, axially. Fire emergency. In a fire emergency, as the PTFE portion of the seat deteriorates, the metal portion of the seat maintains the integrity of the seal. There is no interruption of the seal. This also illustrates how the allmetal seat seals.

7 In case of fire continuous sealing. In case of fire, the metaltometal seal is uninterrupted. In case of a partial burn, where the PTFE does not completely deteriorate, the metaltometal seal continues without interruption. With many other valves, the seal is temporarily lost during the early, critical stages of a fire. In the Tufline valve, whether the PTFE is partially or completely destroyed, the seal is maintained. High temperature sealing. The PEEK (Polyetheretherketone) seat provides superior threepoint, bidirectional sealing when operating temperatures will not exceed 7 F. The PEEK seat in valves up to inches meets ANSI/FCI702 Class V leakage specifications. Twopoint, pressureassisted sealing in the allmetal seat operates up to 000 F. Pressure assisted sealing. Like the membrane seat, these seats are axially pliant. In the closed position, flow in either direction tightens the seat against the disc. 7

8 An adaptable design for specialized service. This is an extremely versatile valve. Choose from options and reconfigurations that meet your specific application requirements. In each case, the valve maintains the superior sealing characteristics and longterm economy of the standard Tufline design. Vacuum service. Standard valves can be used to 2 mm mercury (Hg). Special cleaning, to minimize outgassing, is required for service to x 0 mm of mercury. Steam. Standard valves with reinforced PFFW (ST2) seats can be used in saturated steam applications up to psia and 0 F. Steam jacketed and internally steam traced. For processing solidifying or agglomerating media, the Tufline STJ offers a patented point heating system. The design includes an integral, full body steam jacket, a steam traced shaft, and steam tracing of the full circumference of the disc. Xomox 7 (HT2) seats can be used for saturated and superheated steam applications up to 7 F. s with CFM stainless steel bodies are recommended for use in steam applications. Oxygen and chlorine. s designated for oxygen or chlorine service are thoroughly cleaned and dried per Tufline oxygen and chlorine cleaning standards. After they are tested, valves are packaged and sealed in plastic containers. NACE trim. s are available to meet the latest NACE specifications for materials used in sour environments: NACE MR07 / ISO and NACE MR000. This valve performs well in applications such as sour gas, sour oil, or other medias that can cause sulfide stress cracking or chloride stress cracking. Fugitive emissions control. The Tufline emissions control valve is available with an auxiliary liveloaded packing option. There are two full sets of packing separated by a lantern ring. Also available is an optional leakoff port.

For double set with leakoff consult factory. 0 F maximum in steam service. Consult factory for P limitations on shaft materials other than 7 PH. For information on 0" " Tufline High Performance Butterfly s, see Xomox Brochure 2. For sizes and materials not shown, consult factory. For bidirectional dead end service, you must use body type, 2, or 2 valves. These valves have retainers specially designed for such service. Use of body type 0,,, or valves in such service will result in massive leakage. 22

23 Xomox & Matryx Actuators. Tufline s are available as part of a complete valve package. Actuators are available in three models: Double acting vane Rack & pinion spring return Electric Tufline automated valve packages assure you of singlesource responsibility for flow control equipment. With Tufline valves, Matryx and Xomox actuators, Xomox control accessories, and Tufline problem solving expertise, you are assured of valve packages that will provide optimum performance in your application. Comprehensive sidebyside testing confirms that the Matryx and Xomox rack and pinion actuators provide longer service life with more consistent torque. Solid performance data means processors can size actuators with more of a confidence factor and less of a fudgefactor. Initial cost, repair costs, replacement costs, and costly downtime can all be reduced. Rack and pinion actuators are available in both doubleacting and springreturn models with both 90 and 0 rotation. Xomox Automation & Service Centers.
