®
G2 Series Two-Way
Application
G2 Series two-way valves control water or steam for 2-position
or modulating control applications. Valves conform to ANSI
class 250 rating for screwed cast bronze bodies.
Actuators
A number of combinations are possible. Both spring return
(NVF…) and non-spring return actuators (NV…) are available.
Piping
The valve should be mounted in a weather-protected area in a
location that is within the ambient limits of the actuator. Allow
sufficient room for valve with actuator and for service. Allow 6”
for cover removal and 12” for complete actuator removal. The
assembly can be mounted with the actuator vertical or horizontal
in relation to the pipe. G2 series two-way “A” port is inlet, “AB”
port is outlet (Do not reverse flow direction).

Note: The NV/NVF actuator cannot be used for 2-way steam applications above
15 psi inlet pressure. For inlet pressures between 15 psi and 35 psi, call Belimo
for standard G2 Series valve with another Belimo actuator. For steam
applications exceeding 35 psi, stainless steel trim must be used. Call Belimo
for pricing.
