The 209 Series Flange Sand Traps are designed to provide unrestricted flow of sand to enhance traction between the wheel and rail. The 209 Series Traps are lightweight with a low profile for those under the platform locations and/or on the truck-mounted sandbox typically found on an industrial type locomotive or light rail vehicle. Horizontal or vertical outlets make it possible to locate the trap with a minimal length of sand hose. Three models are offered to control the sand delivery you require. One with a 1/16" orifice (209-FC-1), a second with a 5/64" orifice (209-FC) and a third model with no orifice (209-F). An adjustable nozzle is used with each model which, along with the integral orifice, allows the sand delivery to be adjusted to meet your operating needs. Choose a GW normally closed solenoid valve to provide the compressed air necessary to move the sand from the 209 Series Sand Trap.
