Dry Riser System Equipment

Dry Riser systems comprise vertical mains normally fitted into staircase enclosures with outlet valves on each floor ready to deliver a supply of water to fire fighting hoses. An external inlet valve at ground level enables connection with a water supply, normally from a fire appliance. Dry risers are normally installed in buildings which are more than 18m high, although if a building has more than 18 storeys then a wet riser (which is permanently charged with water) will be installed.

    1. BSI Landing Valve

      Landing Valves are used for fighting fire with water and accordingly mounted in fire hydrant system at Internal or External places. The landing valves are sometimes also referred to as internal hydrants because they are usually fitted inside the buildings for wet hydrant system.

    1. BSI Pressure Regulating Valve

      Pressure reducing oblique landing valves are suitable for installation on wet risers in buildings for fire fighting purposes, permanently charged with water from a pressurized supply. These landing valves are pressure reducing type designed to provide a range of outlet pressure (5 bar - 8 bar).

    1. BSI Breeching Inlet

      The breeching inlet can only be used in dry riser systems. The inlet connection is installed at the entrance of fire building, while the outlet connection is installed at a special spot.
