HD Deluge Valve

The Model H3 is an automatic-reset deluge valve engineered for high-demand environments. Constructed from high-strength Ductile Iron (ASTM A536), it is built to handle service pressures up to 17.5 bar (250 PSI). The valve operates via a flexible diaphragm that provides a drip-tight, rubber-to-metal seal, ensuring the system remains secure until triggered. Because it has no internal hinges or pistons, the H3 is simple to maintain and can be serviced entirely without being removed from the pipeline. Its versatility is a key feature, as it can be mounted horizontally or vertically and is easily trimmed for various actuation methods, including manual, remote solenoid, or pilot line activation.
