Kingsway Free Fall Fire Valve Kits
The Kingsway range of Free Fall Fire Valves provide a compact, leak proof position action mechanism that can be installed in either horizontal or vertical pipe runs on oil, gas or any other form of non-aggressive media. The valve may be used for either cut off or dump applications. The free-fall linkage allows the weight to start to fall before it is required to move the valve lever. This allows the weight to achieve the required momentum to active the mechanism.

The Valve may be installed in either horizontal or vertical pipe providing it is orientated such that the plug is parallel to the ground. Ensure that any pipe expansion or misalignment will not distort the valve body as this will cause it to stick.
Fit the lever onto the square valve shaft and tighten the fixing screw. Make sure that the lever travels freely from 45° up to 45° down. Attach the free-fall linkage and weight(s) to the lever using the supplied nuts and bolts as shown in the diagrams. If using a 4", 5" or 6" valve, multiple weights and the pulley arrangement must be used as shown below.
DO NOT tighten the bolt through the lever and free-fall link too tight as the free-fall link MUST be able to slide freely.
Finally fit the spring and cable to the top of the free-fall link. The cable should run vertically from the spring to the first pulley.
The cable should then pass over any anticipated fire hazards with fusible link(s) installed in the cable 0.3 to 1.0m above the hazard. The cable may then be routed to a manual quick release by the exit or terminated at a wall anchor by means of crimping.
