Landon Kingsway Free Fall Fire Valves

Screw Type Fire Valve Sets

The Landon Kingsway range of free fall fire valves provide a compact, leak-proof positive action mechanism that can be installed in either horizontal or vertical pipe runs on oil or any non-aggressive media.

The free-fall linkage allows the weight to start to fall before it is required to move the valve lever. This makes sure that the weight achieves sufficient momentum.
