1516-01 THRU -2 AND 1517-1 AND -2 OIL SHUTOFF VALVES
3
1516/1517 Oil Shutoff Valves should be ordered in a configura- tion compatible with planned piping, but if OPEN/SHUT indica- tor is not visible when valve is installed, top assembly can be rotated (in 90° increments for 1" and 1 ¼ " sizes) by following procedures outlined below. NOTE: OPEN/SHUT indicator of these valves should never face upward. Motor sideplate (motorized valves only) should always be vertical.

1. Shut off all electrical power to valve and close upstream gas or oil cock.

2. Remove side cover (or terminal access plate, if used) and disconnect incoming lead wires (tag carefully for reassembly).
3. Remove conduit and leads.
WARNING: Do not attempt field repair of valve body, top assembly, or motor drive unit. Any alterations could be dangerous, and will void all warranties.
4. Note position of signal switch wands.
5. Remove the body bolts (two or four depending on valve size) with 3⁄8 " 12 point sock. 6.Gently lift top assembly NOT MORE THAN ¼ ", just enough to break the seal between the valve body and the Buna "N" rubber gasket. WARNING: Lifting too far may dislodge some small parts inside the top housing, requiring complex reassembly and retesting by trained factory personnel. 7. Carefully rotate top assembly 30° past, and then back to the desired position, in a plane parallel to the top of the valve body casting . 8.Align bolt clearance holes in valve bodycasting with cor- responding tapped holes in the bottom of top assembly .
10. Reconnect conduit and electrical leads.
11. Energize and cycle valve serveral times from closed, in- termediate, and fully-open positions to prove it operates properly. 12. Replace top cover and screws, and place valve in service after careful operational testing. If satisfactory, replace side- plate. Ensure that signal swtich wands have not been disen- gaged and that interference does not exist at OPEN/ SHUT indicator. Failure to do so can result in faulty operation and extensive valve damage.
9.Reinsert bolts carefully engaging threads, and tighten securely.
