This FM approved valve combines the characteristics of a manual ball valve with the added safety of an automatic shut-off. Heat actuated, UL listed thermal links automatically shut-off or open the valve at predetermined temperatures. A unique, removable handle allows the valve to be manually operated without affecting the fusible links. The thermal shut-off ball valve, ranging in size from 1/4″ to 4″, is available in a variety of metals, including stainless steel, carbon steel, monel, Inconel, hastelloy B & C and alloy 20.
Typical applications include shutting down hazardous lines or activating sprinkler systems for fire control.
