Thermal Shut-Off Valves

Fire-Safe Protection by Strahman Group 

BI-TORQ Thermal Shut-Off Valves provide automatic fire protection for systems handling flammable gases and liquids, including fuels, solvents, alcohol, and toxic chemicals. Designed for industrial, commercial, and institutional applications, our valves ensure maximum safety and reliability in fire emergencies. 

Engineered for Safety and Performance 

Backed by Strahman Group’s legacy of innovation, BI-TORQ thermal shut-off valves are built for superior performance and peace of mind. Key features include: 

• Automatic activation at high temperatures to prevent hazardous fluid flow. 
• Fire-safe, durable construction for long-lasting protection. 
• Versatile integration with existing valve systems and plant-specified requirements. 
• Precision-engineered actuation systems for local or remote shut-off. 
• Comprehensive testing to meet fire-safety and industry regulations.

Thermal Shut-Off Fusible Link Packages (FLP Series) 

These assemblies are designed for localized fire-safe isolation, providing sentry-type protection for critical applications. Our thermal shut-off valves combine an API 607 fire-safe valve and a thermal shut-off actuator (topworks) offering a complete assembly providing true isolation to contain flow during a fire. 

• FM-approved actuators for assemblies up to 3,960 in/lbs of torque. 
• Compatible with fire-safe certified quarter-turn ball, butterfly, and plug valves up to 21,390 in/lbs. 
• Ideal for facilities requiring plant-specified valve solutions—custom adapter kits available for leading manufacturers. 
• In-house assembly and testing by our experts ensures seamless integration. 
• Optional start-up and commissioning services for a complete turnkey solution. 

Thermal-Electric Shut-Off Valves (TES Series) 

This innovative system provides local and remote fire protection with the ability to systematically shut down a large group of valves from a central control point, enhancing safety and operational efficiency. These systems are for indoor use only in a controlled environment. 

• Low-voltage operation enables remote activation via PLC or command device. 
• Triggers automatic valve open or closure (depending on what is ordered) when ambient temperatures exceed the fusible link rating. 
• Controls single or multiple valves from a central location, eliminating the need for compressors or pneumatic lines. 
• Cost-effective, easy-to-install solution that simplifies fire safety infrastructure. 
• Not FM approved.
