Express Fill Circuit
The Express Fill circuit may be used for filling from the Taylor-Wharton Express Truck or for top filling by a
cryogenic pump. Two check valves (CV-1 & CV-2) prevent product from escaping the vessel.
A fill stop valve (FSV-1) within the vessel prevents over filling. This device functions when filled by the
Taylor-Wharton Express Truck in automatic fill mode. The fill stop valve will not function when the vessel is
filled by a typical cryogenic pump.
