INSTALLATION
IMPORTANT:
The V5055 Valve is designed to provide control
of gaseous fuel (natural and LP gas) flow in
applications in which there is minimal exposure to
water. V5055 Valves used in maritime, beverage,
food processing, outdoor and other installations in
which occasional exposure to water is experienced
may be subject to valve stem and spring corrosion.
The presence of corrosion decreases the operating
life of the valve. V5055 Valves used in such
installations should be inspected at least annually and
should have the valve bonnets replaced if corrosion is
noted.
A V4055 Valve Actuator with a NEMA 4 rating is also
recommended for such installations. The water-tight
design of the NEMA 4 rated V4055 Actuator prevents
water from entering the V4055 valve stem and spring
chamber through the actuator. Under certain
conditions, some water may be retained by the
external upper portion of the valve body. The retained
water is effectively excluded from the valve stem and
spring chamber by a functional seal that is
incorporated into the NEMA 4 rated actuator.
