An inflate/deflate valve of a heavy duty design for use during inflation of inflatable devices such as dunnage bags. Such dunnage bags are used in hostile or rough environments where when deflated the dunnage bags are stacked and compressed into storage drums where the inflate/deflate valves may be crushed or forced against the cuttable or ripable dunnage bag material. As a result, a novel and unique design is provided including a valve body, a spring, an optional washer, a spring retainer, a poppet, poppet seal and an o-ring.
