3/4 Inch Zinc-Plated Cast Iron 90 Degree Anti-Siphon Valve With Field-Selectable 0-20 Foot Range Hydrostatic Head Springs And 15-35 PSI Pressure Relief
Item No. 403PR-34
The Model 403PR Anti-Siphon Valve With Pressure Relief is used to reduce fire hazards and prevent fuel spillage in aboveground storage tanks with top discharge. Should the line rupture, the anti-siphon valve stops the effect of fuel being siphoned out of the tank, preventing spillage in the surrounding area. Pressure relief relieves thermal expansion in the line back to the tank. Valve includes (4) field-selectable color-coded springs that cover an operating range of 0-20 foot hydrostatic head. Save inventory space and avoid confusion with different head settings when ordering.
