Fisher GX General Service Control Valve
Fisher® GX is a compact, state-of-the-art control valve and actuator system, designed to control a wide range of process liquids, gases, and vapors
It is designed to meet the requirements of both EN and ASME standards. Valve body sizes DN 15 to DN 100 (NPS 1/2 through 4) and pressure classes PN 10-40 CL150 and 300.Shutoff capabilities of Class IV, V and VI.It is available with a complete accessory package, including the FIELDVUE™ series digital valve controller and optional metal bellows seal.
Optimized valve and actuator system. Product simplicity and ease
of selection form the foundation of the GX. Mounted with a digital or
analog positioner, the GX provides high performance control across a
wide range of process applications.
Compact actuator design.
The GX utilizes a compact, multi-spring actuator. The GX design has been
optimized to eliminate complicated actuator sizing procedures - once
the valve body, port size, and air supply pressure are selected, the
actuator size is fixed.
Modular design. The design
architecture has been optimized to maximize the use of common parts
across sizes. The actuator stem and stem connector are used across all
GX sizes. The GX actuator uses a total of 5 different springs across all
valve sizes. These spring sets have been optimized to allow for maximum
application coverage. The plug/stem assemblies and packing sets are
common across several sizes, as well.
Low lifetime costs. Reduced product complexity, low parts count, and part commonality all contribute to reduced inventory and maintenance costs.
