Definox DPAX DN25 80 Spring Pressure Check Valve with Control Top is a spring-loaded backflow prevention valve designed for DN25 piping. The DN25 designation indicates a nominal 25 mm connection size, and this valve is part of Definox's DPAX line with a Control Top feature. In piping systems, a check valve like this prevents reverse flow, ensuring one-way flow at the 25 mm connection scale.
