Ductile Iron Valve Box‑Guarda llave 200/400
These ductile iron valve boxes (local Chilean name: Guarda llave), including Guarda llave 200 and Guarda llave 400 models, are purpose‑built for Chile municipal potable‑water distribution networks.
The assembly consists of a cast box body and a hinged flip‑open cast iron cover.
The bottom of each housing is designed with arched cut‑outs to allow underground service pipelines to pass through.
The hinged lid can be pivoted open, giving convenient access for field operation, inspection and maintenance of the buried water stop valves.
Guarda llave 200 is the shorter‑height version with 200 mm body height for shallower burial conditions, while Guarda llave 400 is the taller 400 mm variant for deeper laying depth.
Heavy‑duty cast construction protects underground valves from pavement loads, soil compression and surface damage within urban sidewalks and public pedestrian zones.
- Chile local municipal water series: two available heights
- Guarda llave 200 (200 mm) and Guarda llave 400 (400 mm), matching different pipeline burial depths
- Material: high‑strength ductile iron casting for main housing body and hinged cover
- Hinged flip‑open cover design; cover engraved with “AGUA POTABLE” marking for potable‑water service identification
- Bottom arched cut‑outs enable the water pipeline to run through the valve box
- Two dimension alternatives: short‑height model for shallow installation, tall model offers larger internal working space for deeper‑buried valves
- Robust cast structure withstands pedestrian and light‑traffic pavement loads
- Black bituminous anti‑corrosion coating for underground buried application
- Square compact outer profile, suitable for sidewalks and urban public walkway installation
