LINE TYPE PROPORTIONER
Proportioner systems work on the principle of water flow and pressure difference. The water coming from the system exerts pressure on the concentrated liquid and carries the pressurized liquid to the proportioning device. Then, the foam and water solution is piped to the discharge devices in the danger area. Each proportioner consists of cast stainless steel, bronze and brass and the internal parts are made from stainless steel 316 and a measuring orifice. The proportioner is available in two standard sizes ranging from DN 100 to DN 150 and flow ranges from 500 Lpm to 8,000 Lpm and is designed to fit between two DIN PN 16 (ANSI Class 150) pipe flanges.
