Production introduction
foinbo® 2-way breeching inlet valve is a critical component in fire protection systems, designed to facilitate rapid connection to water supplies during emergencies. Typically installed at ground level within dry or wet riser mains of 4" (100mm) or 6" (150mm) diameter pipes, this valve provides easy access for firefighting teams to charge the system with water.
Constructed with robust materials such as spheroidal graphite iron for the valve body and BS1400 LG2 gunmetal or copper alloy parts for the inlet connection, the valve ensures durability and corrosion resistance. The inlet connection often includes a bronze spring and washer, while the locknut is made of stainless steel for enhanced strength. The valve is equipped with rubber blanking caps secured by chrome chains, though brass or gunmetal caps are available upon request.
The flange connection adheres to standards such as BS 4504/PN16, ensuring compatibility with various piping systems. The valve's compact design optimizes flow characteristics, and it is hydrostatically tested to 20 bar, with non-return valves tested to 1.7 bar, guaranteeing reliability under pressure.
