Thermal Shutdown Valves for Fire Protection Systems FLP SERIES COMPLETE ASSEMBLIES BI-TORQ Valve Automation s complete line of API 0 certified quarter-turn valves suit a wide range of applications. Carbon and stainless steel ball valves are available in / through sizes with ANSI flanges and NPT, socket weld or BSP ends. Fire safe high performance butterfly valves come in through sizes. ONE VALVE DOES IT ALL Our unique design allows a single valve to be used as an armed fail safe assembly AND as a manually operated valve, saving money, space and maintenance time. Smaller valves use the standard handle while larger ball valves and all butterfly valves have a declutchable manual override. FL SERIES BALL AML OR & SPECIFIED BUTTERFLY VALVES In addition to our own valves, we manufacture customized assemblies for a range of customer-specified quarter turn valves. In addition, a retrofit assembly can be used where safety regulations dictate the addition of a fusible link on valves currently installed. PRODUCT CONFIGURATOR The product configurator on bitorq.com allows users to build assemblies, create part numbers, and download product documentation. Registered users can get CAD drawings and Solidworks models ready to drop into a customer installation schematic. Product models can be compared with all available options so that engineers and specifiers get the unit they need. BI-TORQ S THERMAL SHUTDOWN FIRE SAFE VALVES HELP MEET INSURANCE REQUIREMENTS FEATURES BI-TORQ Valve Automation fusible link assemblies are used in a wide range of applications, including: tank farms refineries chemical production airport and truck fueling stations petrochemical and biofuels paint and toxic chemicals Automatic shut-off in case of fire FM-Approval on most assemblies API 0 fire safe approval on all ball and butterfly valves Valve can be operated even while spring pack is armed UL or FM-approved links available Heavy duty arming device Factory assembled and tested Link temperatures from F to 0 F Fail open or fail closed orientations for a variety of applications BI-TORQ Valve Automation PO Box 0 N00 Linlar Dr. La Fox, IL 0 www.bitorq.com

NOTE: CANNOT BE USED ON FM- APPROVED ASSEMBLIES BI-TORQ Valve Automation and our soldered fusible link manufacturers suggest the annual replacement of fusible links as part of scheduled plant maintenance. CONTINUOUS POSITION INDICATION This one-of-a-kind design incorporates one or two proximity switches as an integral part of the assembly, allowing a remote operator to continuously record the position of the valve. This is especially crucial in fire safe applications where valves need to be monitored as part of a process system. Special enclosures allow the switches to maintain position signal even in high temperatures. (NOTE: Not available on all units.) LT and HT fusible link assemblies including proximity switches AUTOMATIC FIRING LINK Our newest innovation allows an operator to manually trigger the armed fusible link when a voltage signal generates the heat necessary to cause the link to yield. This lets plant personnel shut down flammable liquid lines immediately even if a fire has started in another area. Please contact our technical sales personnel for more application information.
