Inquiry (采购产品): check valves we have a contract with the USMC in providing an expeditionary fuel system. besides issuing fuel to vehicle and equipment the fuel bladders can be used as an auxilliary fuel tank. I am looking for a check valve (?) that will shut off if the line is cut/damaged. **** Hidden Message ***** David Livingston 1200 W Benedum Industrial Dr. Bridgeport, WV 26330 USA Company: FMW Composite Systems Inc.
