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. The pump / top fill valve (V-1) is a quarter-turn ball valve permitting filling of the vessel. A
check valve (CV-1) prevents product from escaping should the pump / top fill valve be opened inadvertently.
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.
