The Woodward GSOV25 gas shutoff valve provides extremely fast shutoff of gaseous fuel flow for industrial gas turbines. Designed for both emergency and normal shutdown operation, the GSOV25 achieves zero leakage from inlet to outlet when closed, with stainless steel construction for corrosion resistance in severe service conditions.
