SOLBERG Proportioning Devices


When it comes to Proportioning Devices, SOLBERG Proportioning Devices are the hardware you need to get the job done right—no matter what type of foam system.

Foam Pump Proportioner

SOLBERG Proportioning Devices include the Solberg Foam Pump Proportioner (SFPP) is a low foam solution proportioning device, designed to accurately proportion the foam concentrate into the water stream at both high and low system flow rates. The Solberg Foam Pump Proportioner is designed as an integral component of the Solberg Foam Pump Proportioning System. The pump proportioner is designd for open and closed head foam/water sprinkler systems, foam monitor systems, and other SOLBERG foam discharge devices. Please consult product datasheet for complete details.

Foam Ratio Controller

Solberg Ratio Controllers are a modified venture device designed to meter the correct amount of foam concentrate into a water stream over a specified range of flow and pressure rates with minimal pressure loss. The ratio controller consists of three components: the body with water inlet, metering orifice located in the foam concentrate inlet, and throat (nozzle) located downstream from the water inlet. The ratio controller is manufactured in four sizes 3.0″, 4.0″, 6.0″ and 8.0″ (76 mm, 102 mm, 152 mm, 203 mm).
Inline Balanced Pressure Proportioners

The SOLBERG® Inline Balanced Pressure (ILBP) proportioner is a complete self-contained device that incorporates the necessary components including ratio controller, duplex gauge, balancing valve, check valve, ball valve, and associated brass piping. SOLBERG ILBPs are designed to balance the incoming foam concentrate pressure with the incoming fire-water pressure, and meter the correct amount of foam concentrate to fire-water stream over a wide range of flow rates and pressures.

The ILBP system works with a positive displacement foam pump, to supply foam concentrate to the ILBP. A pressure sustaining valve, located in the return line, carries excess foam concentrate not needed by the device back to the atmospheric storage tank. Devices are available in sizes ranging from 2.0″ – 8.0″ (51 mm – 203 mm).
