Dedicated Thermally Activated Shut-Off Valves

The TSV series Thermal Shut-off valves combine a fire-safe ball or butterfly valve with a pneumatic actuator and the FM approved FireChek® valve to form a dedicated stand-alone thermal shut-off valve that will close (or open) at a given temperature (165 ̊F standard). This alternative to fusible link valves can be tested and reset without the need to replace any hardware.

The valve is held open by charging the actuator through a Schrader (check) valve. There is a clearly labeled gauge to indicate the proper pressure range to maintain. TSV’s have passed both Mil-std-810G humidity and vibration testing procedures through an independent third party. Each TSV assembly is also individually tested by a qualified technician in our ISO certified facility after assembly.
