Landing Valve Oblique

A. An Landing Valve Oblique is a specialized firefighting valve used in dry riser or wet riser systems. It is installed on each floor of a building and features an angled design (typically 45 degrees) for easy hose connection and operation. Made from durable materials like brass or gunmetal, it ensures reliable performance under high-pressure conditions.

A:The primary purpose of an Oblique Landing Valve is to provide firefighters with a controlled water supply on each floor of a building during emergencies. It ensures quick and efficient access to water, especially in high-rise buildings where firefighting operations can be challenging.

A. To use an Oblique Landing Valve:

Connect a fire hose to the valve's instantaneous female coupling (usually 63mm or 2.5 inches).

Open the valve by turning the handwheel or lever to allow water flow.

Direct the hose to the fire-affected area and begin firefighting operations.

Close the valve after use to stop the water flow.

A. Oblique Landing Valves are used in:

High-rise buildings (residential, commercial, or industrial).

Public buildings (hospitals, schools, shopping malls).

Industrial facilities with fire safety requirements.

Any structure equipped with dry riser or wet riser systems.

A. We should use Oblique Landing Valves because:

They provide quick and reliable access to water for firefighting on every floor of a building.

Their angled design ensures ease of operation in confined spaces.

They are durable and compliant with fire safety standards (e.g., BS 5041, NFPA).

They are essential for life safety and property protection in high-rise and large buildings.
