411G - 3/4" NPT, #38 Orifice, 600 PSI, Inverted Bucket Trap

The Model 411G is for vertical installation, and offers smaller capacities at higher pressures. 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.
