faq: items: - question: What bottom-tank conditions are Bray Tank Series ball valves suitable for? answer: The Tank Series is specifically designed for bottom drainage positions of autoclaves, reactors, pressure vessels, and storage tanks. The full-port design helps achieve fast and unobstructed media discharge, suitable for applications requiring reduced tank bottom residue. - question: What are the differences between TKF15 and TK7000/TK8000 in structure and maintenance? answer: TKF15 is a two-piece design offering flush-bottom welded connection to the tank and ASME B16.5 pipe flange connection, suitable for NPS 2½ to 10 large storage tanks. TK7000/TK8000 features a three-piece swing-out body design for easy in-line cleaning and in-line maintenance, and provides more end connection options. Specific configuration depends on the actual model and application conditions. - question: How to select pressure rating and size for Tank Series ball valves? answer: TK7000/TK8000 sizes range from NPS 1 to 6, with NPS 1 to 4 rated at 1000 psi WOG maximum allowable working pressure; pressure rating for larger sizes depends on the actual model. TKF15 sizes range from NPS 2½ to 10, with 316SS body rated at 275 psi and WCB body at 285 psi. Selection should consider size, body material, media, and system pressure conditions. - question: What sealing and seat designs does the Tank Series use? Can it be used for demanding leakage control applications? answer: The series features modified TFM seats, continuously pre-loaded packing, and zero-leakage sealing design, meeting reliable sealing requirements for bottom-tank conditions. Both ball and stem are made of stainless steel, and valves are tested to API 598 standard. - question: Is the Tank Series easy to install with an actuator, and what connection options are available? answer: The Tank Series features an integrally cast top mounting flange to simplify actuator installation and enhance structural durability. TK7000/TK8000 offer flanged, threaded, socket weld, butt weld, extended socket, extended butt weld, quick clamp, and tube end connection options; actual end connection depends on the specific model.
Product Overview
Durable ball valve for autoclaves, reactors, and storage tanks with zero-leakage sealing
Integral Flange Design Simplifies Actuator Installation and Enhances Durability
The Tank Series TKF15 2-piece and TK7000/TK8000 3-piece full-port ball valves are designed to meet industry requirements for autoclaves, reactors, pressure vessels, and storage tank bottom drain positions. The TK series valves enable fast and unobstructed media discharge from tanks. Tank Series valves feature zero-leakage sealing, continuously pre-loaded packing, and an integrally cast top mounting flange for easy actuator installation and robust construction. All Tank Series valves offer low operating torque and long service life. The TKF15 Tank Series 2-piece ball valve features an integrally cast shut-off design with the tank bottom, providing flush-bottom welded connection to the tank and ASME B16.5 pipe flange connection. The TKF15 series is an economical solution for NPS 2½” to 10” large storage tanks. The TK7000/TK8000 Tank Series three-piece ball valves feature a swing-out body design for easy in-line cleaning and in-line maintenance. The 3-piece TK series offers multiple end connection options, including flanged, threaded, socket weld, extended socket, butt weld, extended butt weld, quick clamp, and tube end/extended tube end, providing maximum flexibility.
