FA Pressure Foam Proportional Inductor
The Pressure Foam Proportional Inductor features a proportional mixer flange to ANSI/BS4504/GB standards, a galvanized pipe valve body with spray painting. It suits high/medium/low foam systems, ensures 1.3%-6% foam mixing via water pressure, offers ≤0.05MPa pressure loss, vertical/horizontal installation, and 0.14-1.2MPa operating pressure.

Pressure Foam Proportional Inductor
DN100/150/200
Specifications
1. Proportional mixer flange standard: ANSI / BS4504 / GB;
2. Valve body material: galvanized pipe;
3. Surface treatment: spray painting
Application scenarios
Applicable to high, medium and low multiple foam fire extinguishing systems, especially suitable for scenarios that require stable mixing accuracy and large pressure range changes (such as oil storage tanks, chemical facilities, airports, etc.)
Working principle
When pressurized water flows through the proportional mixer:
1.3%-6% of the pressurized water enters the foam tank to squeeze the capsule and replaces an equal amount of foam liquid;
2. The remaining 94%-97% of the water and the foam liquid are accurately mixed in the mixer;
3. The foam mixture is formed and transported to the fire extinguishing device.
Features
1. High mixing accuracy: small proportional error and strong stability.
2. Low pressure loss: inlet and outlet pressure drop ≤0.05 MPa, high system efficiency.
3. Anti-corrosion and durable: The capsule isolation design extends the life of the foam liquid and reduces the maintenance frequency.
4. Strong adaptability: supports vertical/horizontal installation, covering DN100-DN200 diameter requirements.
Working pressure
1. Operating pressure range: Adaptable system pressure 0.14~1.2 MPa.
2. Pressure bearing capacity: Strength test pressure reaches 4.8 MPa.
