Armstrong 983 Series Inverted Bucket Steam Traps are offered in two sizes of cast steel with in-line horizonal pipe connections and vertical strainers with a choice of screwed, socketweld or flanged connections. A unique leverage system multiplies the force provided by the bucket to open
the valve against system pressure. The mechanism is free-floating, and has no fixed pivots to create wear or friction.
