INSTALLATION
IMPORTANT
The V5097 Valve is designed to provide control of
gaseous fuel (natural and LP gas) flow in applications
with minimum water exposure. V5097 Valves used in
maritime, beverage, food processing, outdoor or other
installations with occasional exposure to water can
develop valve stem and spring corrosion, decreasing
the operating life of the valve. Inspect V5097 Valves
used in these installations annually and replace the
valve bonnets when corrosion is noted.
A valve actuator with a NEMA 4 rating is
recommended for these installations because the
water-tight design of the NEMA 4-rated actuator
prevents water from entering the valve stem and
spring chamber through the actuator. Under certain

conditions, some water can be retained in 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.
