DESCRIPTION
The Buckeye Model FAM - PO Ratio Flow Controller is a proportioning device designed to meter the correct amount of foam concentrate into the water stream over a wide range of flows and pressures. These units are used in conjunction with either a bladder tank or a foam pump proportioning system.
The operating principle of the controller is based upon the use of a modified venturi. As the water passes through the inlet jet, a reduction in pressure in the annular area is created. This reduction allows the metering of the foam concentrate into the water stream
FEATURES
- U.L. Listed.
- Proportioner body and inlet nozzle are cast in ASTM 85-5-5-5 brass. Machine faced to ANSI B16.1 class 12.5.
- The 2 1/2" threaded controller is designed using a 2 1/2" FNPT threaded inlet and a 2 1/2" male NPT threaded outlet. All 3",4", 6" and 8" wafer style ratio controllers are designed to fit between two 150 lb. flat faced pipe flanges. To ensure a complete seal against each flange, each face of the controller is machined with 32 grooves per inch.
- The controller body is clearly marked with a flow direction arrow and label to identify the type of foam concentrate and percentage ratio.
