FM Approved Valve Assemblies for Gas Shut-Off


FM-approved valves and valve assemblies for liquid and gas shutoff are approved to FM class 7400, 7420, and 7422. Providing fast action on shut-off needs, the units feature a spring-return automated ball valve, explosion-proof limit switch, solenoid pilot valve, advanced quarter-turn rack-and-pinion actuator design, superior valve seating, and a patented stem seal system.


Configurable to a wide range of shut-off requirements for build-to-order flexibility at standard model economies, valves are available in 3-piece or flanged models, 316SS or WCB trim, and 0.5 to 6 in. (13 to 152 mm) sizes. The 3-piece valves offer a choice of threaded, socket weld, or butt weld end connections, while flanged valves are available in 150# or 300# flange ratings.


Solenoids are approved for water-proof as well as explosion-proof environments. All the valves feature A-T Control's exclusive pyramidal stem seal system. The live-loaded packing system features 45-deg. pyramidal stem and stem seal with Belleville washers and chevron packing.
