Between Flange

Each ANSUL® proportioner consists of a body, inlet nozzle, and metering orifice, all of which are corrosion-resistant brass. The proportioner body design includes four sizes to fit between a 3 in., 4 in., 6 in., or 8 in. pipe flange. Clearly marked on the proportioner body is the flow direction arrow, as well as the type and percentage of the designated concentrate. The inlet nozzle is secured by a stainless steel retaining ring that is internally concealed to prevent removal after installation. The metering orifice is sized according to the type and percentage of concentrate used and is also secured with a stainless steel retaining ring.
