Kenilworth Combustion is proud to offer to our customers a proactive solution to oil spills caused by transportation transfers. The patented Gate Valve Safety Device (GVSD) and Ball Valve Safety Device (BVSD) are designed to bolt directly to the gate and ball valves commonly used on oil storage tanks. These patented safety devices make it impossible to disconnect transfer hoses before they have closed the valve.  No more accidental spills due to complacency during transferring fluid from the tank to the truck. Install time is quick and requires no down time, the universal fit design allows you to simply bolt on and go. The all steel construction and powder coated finish makes it rugged enough for life in the patch, and the ease of operation ensures that there is no way to use it incorrectly. Take a look at the spec sheets, functional drawings, and videos to see for yourself how simple fluid transfer safety can be!
