Operation
The upper gallery forms a Ø100mm pipe connecting a bolted-on API adaptor to the tanker pipework, so allowing completely normal bottom loading & gravity discharge of individual compartments.
A second, lower, gallery runs at right angles and when bolted together they form an Ø80mm pipe. Discharge from this lower gallery can be from an end fitting or from any of the bottom outlets on each valve.
