Thermal Shut-Off Valves with Customer Owned Valves

Maximize Protection and Performance with Thermal Shut-Off Retrofits

BI-TORQ offers the installation of fire-safe thermal shut-off top works with fusible link assemblies onto customer-supplied, API 607-certified valves. By integrating BI-TORQ top works onto your existing valve, you gain enhanced safety, reliability, and compliance with fire protection standards–backed by our proven manufacturing expertise.

Depending on valve size, torque, and spring pack configuration, FM approval can also be offered on the top works only of the assembled unit. Customer-supplied valves must be shipped to our Bethlehem, PA, facility for installation and testing.
