A-T Controls manufactures FM-approved valve assemblies for liquid and gas vents and safety shut-off requirements. These valve assemblies have received FM approval, certifying their suitability for applications that demand protective measures for fuel-burning equipment by FM classes 7400, 7412, 7420, and 7422. Each assembly comprises a spring return automated ball valve, an explosion-proof limit switch, and a solenoid pilot valve. Customers can choose from two designs for the valves: a 3-piece design, which offers options for threaded, socket weld, or butt weld end connections, and a flanged design, available in ASME Class 150 and 300. These valves come in sizes from 1/4 inch to 6 inches. The assemblies are at the forefront of quarter-turn automation technology, featuring a rack and pinion actuator. In synergy with the assembly's superior valve seating and stem seal design, this actuator ensures reliable and consistent closure and venting as required. These assemblies offer a compact, efficient solution for fuel gas safety shut-off or venting systems.
