Products Description
Overview
The forede® FRD-4BI breeching inlet valves (also called Fire Brigade Inlet Breechings) are vital components in building fire protection systems. They allow firefighters to pump water into the building's fire main or sprinkler system from an external source (like a fire engine), especially when the internal water pressure is insufficient or when the main water supply has failed.

FAQ
Q: Where is a Breeching Inlet Valve installed?
It is typically installed at ground or street level in an accessible location on the building façade, often in a recessed cabinet or enclosure marked "Dry Riser Inlet" or "Wet Riser Inlet."
Q: What is the function of a Breeching Inlet Valve?
The main function is to provide an external water supply connection for firefighters to boost water pressure into the building's riser system, ensuring effective firefighting on upper floors.
Q: What are the types of Breeching Inlet Valves?
Common types include:
2-way breeching inlet valve – two inlets, usually for small to medium buildings.
4-way breeching inlet valve – four inlets, suitable for high-rise or large buildings.
They can also be dry riser or wet riser types depending on the system design.
Q: How does a Breeching Inlet Valve work?
When firefighters connect hoses to the inlets and pump water in, the non-return valves inside prevent backflow and allow water to enter the riser system, supplying the landing valves or sprinklers inside the building.
Q: What materials are used for Breeching Inlet Valves?
They are generally made of gunmetal, bronze, brass, or cast iron with stainless steel springs and washers, ensuring corrosion resistance and durability.
