Ratio Controller

Product Code No. SS – 125
Specification / Standard The Ratio Controller operates on venture principle. As the water flow through the controller, a low-pressure area is created inside the controller at the diffuser area. Due to this the foam concentrates flow through a metering orifice at the concentrate inlet and to the controller. As the system demand varies, the water flow through ratio controller increases or decreases which in turn proportionately create variation in the low-pressure area making pressure variation at the foam concentrate metering orifice offering proportionate pressure in foam concentrate supply in line with the water pressure in order to balance the proportioning system.
Size 65, 80, 100 & 150 NB
Maximum Service Pressure 14 bar (200 PSI)
Flange Connection ANSI B 16.5 Class 150#
Finish Fire Red / Natural finish.
