Wide Range Proportioner

Proportioners

Wide Range Proportioner is used to proportion foam concentrate to a water source with a wide flow and pressure range. Incoming water applies pressure to the concentrate in the membrane and carries the pressurized concentrate to the proportioning device. Proportioners have bronze and stainless steel bodies and internals made of 316 stainless steel and measurement orifice. Foam proportioners create a foam mixture to be directed to the distribution network pipes by contacting foam concentrate with water at the desired mixing percentage. These systems are ideal for foam spray systems in fire extinguishing systems. Proportioning devices mounted on the mixer body of the bladder tank maintain mixing accuracy over a wide flow rate range and adjust water and foam sections as the flow changes. There are 2 options among standard sizes and the flow range varies between 100 Lpm and 12,000 Lpm. Proportioners are generally calibrated at %1-%3-%6 ratios.
