Armstrong 971 Series Inverted Bucket Steam Traps are cast steel inverted bucket steam trap with 1/2" NPT in-line horizontal pipe connections and maximum operating pressure of 600 psi (5/64" orifice). The Series 970 has a unique leverage system that multiplies the force provided by the bucket to open the valve against system pressure. The free-floating mechanism has no fixed pivots to create wear or friction. Because the mechanism is at the top of the trap, no dirt can collect on the orifice. The tiny particles of dirt remain in suspension until discharged by the full differential purging action when the bucket sinks, pulling the valve off the seat. The discharge orifice is surrounded by a water seal, preventing live steam loss. Automatic air venting is possible by a small vent hole in the bucket, which provides continuous automatic air and CO2 venting at steam temperature. Inverted bucket traps drain continuously, discharging intermittently, allowing no condensation backup. They are also resistant to water-hammer.
