MTVLOS
Mantern
The "oblique" design refers to the angled configuration of the valve body, which makes hose connection and operation easier, especially in confined spaces like stairwells and riser cupboards.
Applications
Installed on wet risers inside multi-storey buildings (usually at every floor landing or stairwell).
Provides immediate water supply to firefighters during firefighting operations.
Used in commercial, industrial, and residential high-rise buildings where firefighting access is required.
Advantages of Oblique Landing Valves
Angled outlet simplifies hose coupling in narrow staircases or riser rooms.
Durable construction (typically made from gunmetal, brass, or stainless steel).
Reliable under high-pressure firefighting conditions.
Designed to work with standard fire hoses and couplings.
