10.0 MAINTENANCE
This valve should be disconnected, cleaned and visually inspected inside and out at least twice annually, or as water
quality and use may require. Moving parts such as hand wheels, valve ball and couplings should be checked for smooth
and free operation. Seals shall be greased as needed with a Silicone based grease such as Dow Corning 112. Any scrapes
that expose bare aluminum should be cleaned and touched up with enamel paint such as Rust-Oleum. Replace any
missing or damaged parts before returning valve to service.
CAUTION
Dissimilar metals coupled together can cause galvanic corrosion that can result in the
inability to unscrew the threads of complete loss of thread engagement over time. Per
NFPA 1962 (1998 edition), if dissimilar metals are left coupled together an anti-corrosive
lubricant should be applied to the threads. Also the coupling should be disconnected
and inspected at least quarterly.
CAUTION
Any alterations to the Ball Intake Valve and its markings could diminish safety and
constitutes a misuse of this product.
