881 - 3/4" NPT, 1/4" Orifice, 15 PSI, Inverted Bucket Trap

880 Series Inverted Bucket Steam Trap in cast iron for horizontal installation with integral strainer, continuous air venting at steam temperature, free-floating stainless steel mechanism, and discharge orifice at the top of the trap.

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. Because the mechanism is located at the top of the trap, no dirt can collect on the orifice. Small particles of dirt are held in suspension until discharged by the full differential purging action when the bucket sinks, pulling the valve off the seat.
