The HJ20 Jumbo Siamese is built to move serious water. This double clappered, two-way siamese valve is designed for heavy-flow applications where large-diameter hose connections are required. With hardcoat anodized clappers and aluminum construction, it’s tough enough for high-volume, high-pressure demands while maintaining optimal performance and control.
Ideal for fire departments operating in urban and industrial settings, this valve allows two lines to feed into a single large-diameter outlet—making it perfect for supply line management during large-scale incidents.
Features:
Dual clapper valve design prevents backflow and ensures uninterrupted water delivery from one or both inlets
Hardcoat anodized internals for superior corrosion resistance
High-volume water movement, compatible with 4", 5", and 6" Storz hose lines
Optional integrated air bleeder valve for rapid pressure release
Locking Storz fittings for secure, tool-free connections
