3-21. Valve manifolds are made up of what type of modified valve? 1. Globe 2. Gate 3. One-way check 4. Rotary plug 3-22. What device ensures the disk is centered into the base of the valve body in a manifold? 1. Valve stem 2. Gate guide 3. Plug guide 4. Disk guide 3-23. What device prevents leakage around the valve stem of a manifold? 1. O-ring 2. Gasket 3. Packing 4. Plug 3-24. On a manifold, what is the name of the pipe connecting the mainside valve to the tankside valve? 1. Nozzle 2. Coupler 3. Flange joint 4. Tube 3-25. When tanks are ballasted, what must be done to the tankside valve? 1. It must be pinned closed 2. It must be bolted closed 3. It must be locked closed 4. It must be tagged closed 3-26. What type of manifold should be used for the tanktop valves in the stripping system? 1. Double-valved manifold 2. Single-valved manifold 3. Flood and drain manifold 4. Sliding gate manifold 3-27. Which of the following is NOT a function of the flood and drain manifold? 1. Stripping 2. Transferring 3. Ballasting 4. Deballasting 3-28. What device on the flood and drain manifold allows only one valve to be opened at a time? 1. A rotating hook locking device 2. A pinning device 3. A latch-type locking device 4.

Filter element mount assemblies 3. Separator elements 4. Vent lines 3-31. Leakage is prevented at the ends of the filter elements by the 1. smooth surface of the end caps forming a tight seal with rubber gaskets on the elements 2. fiber washers on the elements forming a tight seal against the knife edges on the end caps 3. end caps of the elements being assembled with fiber washers to form a tight seal 4. knife edges on the end caps projecting into the synthetic rubber gaskets on the elements 18
