Thermal links may be furnished U.L. listed for 135°, 165°, 212°, 286°, 360°, and 500° F.

All links are Factory Mutual approved.

Applications include activating spinkler systems for fire control, or shutting off hazardous links in event of fire.

The Essex standard themal shut-off ball valve, THR0001CT, will operate withpressures in excess of 1000 psi at temperatures of -20° to 425° F (for upper limit 500° F thermal link must be used). Standard valves are furnished with 165° F thermal link.

Factory Mutual Approved rating is for flammable liquids nd 125 psi.
