BEFORE INSTALLATION: Ensure that the component materials of the valve being
installed are compatible with the media, with regard to corrosiveness, pressure, and
temperature.
1. Pipe connections to be threaded into these valves should be accurately threaded,
clean and free of dirt and metal shavings.
2. Teflon tape is recommended for use as the pipe joint sealant. This material should
be applied to the manufacturer's specifications.
3. Apply wrench on the hex pads nearest the joint being tightened to any distortion of
the valve body.
1. Piping connections to be soldered into these valves should be cut square and then
cleaned with an appropriate cleaner or flux.
2. These valves are designed to be soft soldered. Apply heat with the flame directed
AWAY from the center of the valve body. Excessive heat can harm the Teflon seats.
Solder valves only in the fully open position.
Lever rotation is clockwise for "OFF" and counterclockwise for "ON". Use only sufficient
force to open valve without damage to stops.
NOTE:
Valves must be installed in piping systems that comply to the applicable
A.N.S.I. B31 Standard. Special considerations must be taken with respect to
pipe line expansions and contractions and the media expansions and
contractions within the piping system.
