GX
Control Valves
Innovation. Technology. Reliability.
Wide Range of Application
The GX product line lets you meet a wide range
of flow and pipeline sizing requirements. A 3-Way
construction is available, which is perfectly suited for
accurate temperature control.
The engineered passages within the GX valve body
provide optimal capacity and create a stable flow
pattern for smooth operation in every valve size.
Actuator sizing and selection is determined
automatically by the valve body configuration. No
extra engineering is required.
The GX actuator controls up to a 51.7 bar (750 psig)
pressure drop. Its multi-spring design is field-
reversible from spring-open to spring-close action.
A carefully selected lineup of valve body and trim
materials means you can apply the GX to a wide
range of service situations. Carbon and stainless
steels are GX standards along with a choice of several
alloys for more corrosive applications.
Metal-to-metal seating is standard, with options
including PTFE soft seating for Class VI shutoff and
hardened trim with a Stellite overlay for erosive
applications.
You can use the GX for either throttling or on-off
control, with or without a positioner. Digital and
analog positioners can be specified, as well as
auxiliary solenoids, limit switches and other
accessories. The GX is compatible with the NAMUR
(IEC 60534-6-1) mounting standard.
E
merson engineers started with a clean slate
in developing Fisher
®
GX control valves. Their
goal was to bring unmatched innovation, technology
and reliability to control valve ownership. GX control
valves are the result. They provide reliable operation
over a wide range of applications and come in a
variety of sizes and materials.
Designed to meet your
needs, digital GX control
valves with integrated

DVC2000
instruments feature
non-contact, linkage-less
technology. DVC2000
instruments give local
indication of valve travel
position and pressure status in one of 7 languages.
No other control valves offer the innovation,
technology and reliability of digital Fisher GX valves.
