Assured Automation, A Top Supplier of Actuated Valves and Flow Components, Does It Again: Unveils Latest in High-Tech Thermal Shut-Off Valves – The ESOV Series

ROSELLE, N.J., Sept. 21, 2023 /PRNewswire/ — Assured Automation continues to impress consumers with their safe, innovative designs, releasing its newest product from the ESOV Series and promising a simple, effective method for closing a valve in emergency and hazardous situations.

Designed with safety in mind, Assured Automation recently released the ESOV series ANSI flanged swing-check valves with fusible links. Combining both practicality with predictability, these valves are manufactured with an external spring load. Held in the open position, they contain a fire-sensitive fusible link. Should the fusible link melt due to fire or extreme temperature, the valve will automatically close, stopping the flow of the liquid, gas, or vapor.

“Our top priority is to design products that have the best interest of our customers,” said one of the lead executives at Assured Automation. “We are thrilled to offer yet another series of products that perform with excellence in mind. The ESOV series comprises state-of-the-art technology that meets the ongoing needs of the industry and our clientele, and we are constantly driven by exceeding industry standards. All valves are tested to API 598.”

Playing a critical role in numerous industries, swing-check valves serve as a simple solution for many different uses. Offering three unique models, including the BPSL (Basic), CPSL (Pneumatic Release), and the MPSL (Electric Release), the ESOV Series also comes in various sizes, materials, trims, and trigger temperatures.
