Protectoseal Expands Product Line by Acquiring Stewart Safety Valve

Bensenville, IL - Protectoseal, a leading manufacturer of Vapor & Flame Control Equipment would like to announce the acquisition of the Stewart Valve Safety Shut-Off Valve product line. The line consists of 20 various models, in ½", ¾", 1", 1 ½" and 2" NPT threaded connections. The units have been granted FM Approval and meet OSHA 1910.106(b)(4)(iv)(c) & 1926.152(i)(4)(iv)(c).

Protectoseal's Heat-Actuated, Safety Shut-Off Valve is specifically designed for installation in the withdrawal lines of flammable or combustible liquid storage tanks. The tank withdrawal line typically supplies fuel to peripheral support and emergency equipment such as generator sets and pump engines found in but not limited to commercial, construction and industrial applications.

The valve is normally held in the open position by a heat-activated element mechanism. In the event of exposure to an external fire source, the element is activated and the valve is closed securely by an internal spring, and the flow of liquid through the line is stopped. Personnel are never placed at risk having to enter a hazardous situation to turn off a valve.

Protectoseal has more than 85 years of experience in providing products and services for the safe handling of flammable liquids and for the controlling of their vapors: Pressure / Vacuum Relief Vents, Emergency Vents, Flame & Detonation Arrester, Tank Blanketing Valves and a variety of specialty tank fittings.
