Overview

About Fuel Gas Shutoff Valves

The Trilogy FGSV Series is an automatic, power-free shutoff for fuel gas systems. The valve threads into the vessel through a 2" connection with a stainless steel float inside. Under normal operation, fuel gas passes through the body to the 1" outlet.

If the liquid level rises to the preset point, the float lifts and drives the stem and nitrile seat closed, shutting off fuel gas to the burner. Two float sizes are available, the FGSV-212 (2" x 12") and FGSV-210 (2" x 10"), with other sizes on request.
