BRONZE QUARTER-TURN (TWO-PIECE) BALL VALVE
INSTALLATION, OPERATION, & MAINTENANCE GUIDE
INSTALLATION
Special considerations must be taken with respect to pipe line expansions and contractions and the media expansion and
contractions within the piping system. Standard Apollo ball valves are bi-directional. They may be installed in either vertical
or horizontal pipe runs without regard to flow direction or stem orientation. Lead free (LF) models are available for potable
water service.
Threaded End Valves
Pipe connections to be threaded into these valves should be clean and free of foreign material or metal shavings. PTFE pipe
tape is recommended for use as the pipe joint sealant. Two wrenches must be used when making up pipe joints to these
valves. Apply one wrench on the valve hex closest to the pipe joint being tightened and the other wrench to the pipe to
prevent transmitting torque through the valve body joint. Typical wrench make-up is 1-1/2 turns after installing the pipe hand-
tight.
Solder End (Sweat) Valves
Refer to ASTM B828 “Standard Practice for Making Capillary Joints by Soldering of Copper Tube and Fittings”. Preheat for
soldering by concentrating the heat on the pipe or tube first, then the valve solder cup, always directing the heat away from
body joint. See figure 1. The extent of this preheating depends on the size of pipe. After preheating direct the heat on the
valve cup area (avoiding the body joint) to aid capillary action in drawing the molten filler metal into the cup. See figure 2.
 Horizontal mounting – start applying the filler metal at the bottom of the joint then upward allowing bottoming portion
to dam up upper portion.
 Valves should only be soldered in either the fully closed position or fully open position.
 Allow completed joints to cool naturally. Quenching with water will cause unnecessary stress on the joint.
 It is recommended to wrap the valve body with wet rags or employ other heat absorbing techniques to avoid
damaging valve seats and thread sealant.
 Tightening stem packing after soldering may be required.
Caution: The Apollo Lead Free alloys do not contain silicon and therefore DO NOT REQUIRE EXTRA HEAT.
Excessive heat input will damage the body seal resulting in leaks at the valve body joint. In extreme cases, seats
and stem packing may also be damaged.
OPERATION
The valve handle is marked showing proper rotation direction for “ON” and “OFF” positions. Standard rotation is clockwise for
“OFF” (closed) and counterclockwise for “ON” (open).
MAINTENANCE
Normal stem packing wear can be compensated for by tightening the packing gland nut. There are two nuts on the
stem. The top nut retains the lever. The bottom nut (packing nut or screw) controls the packing gland. The top nut and the
lever may need to be removed for easy access to the packing nut. Tighten the packing nut clockwise in 1/8 turn increments
until observed leakage stops. (Packing wrench part number H371400 is available to ease this operation.) Reinstall the
handle and handle nut after adjustment.
