The robust GX 3-way valve package isperfectly suited to address the space limitations of theOEM industry.The GX 3-Way is rugged, reliable, and easy to select.The internal valve trim is designed to ensure longservice life and avoiding unnecessary maintenance.The same construction may be used for bothconverging and diverging applications.The GX 3-Way meets the requirements of both EN andASME standards. It is available with a completeaccessory package, including the FIELDVUE DVC2000and FIELDVUE DVC6200 integrated digital valvecontrollers.The GX 3-Way trim characteristics are designed foraccurate temperature control in heat exchangerapplications.nSide-Port Common (SPC)--The side flange is thecommon pipe connection for general converging(flow-mixing) and diverging (flow-splitting) service(see figure 4). Utilizes an unbalanced plug design.nBottom-Port Common (BPC)--A balanced designused for high pressure drop applications. Thebottom flange is the common pipe connection forboth converging and diverging service (see figures 8and 10).nHigh-Temperature Side-Port Common (SPC)-- Theside flange is the common pipe connection forgeneral converging (flow-mixing) and diverging(flow-splitting) service (see figure 2). Utilizes anunbalanced plug design, a stem extension, a yokeextension, and includes ENVIRO-SEAL graphiteULF packing (figure 14) and a hard-faced seat ring.www.Fisher.comW9557Fisher GX 3-Way Control Valve, Actuator, and FIELDVUEDVC2000 Digital Valve ControllerGE49204X0176Fisher GX 3-Way High-Temperature Control Valve andActuator

Productsimplicity and ease of selection form the foundation ofthe GX 3-Way. Mounted with a digital or analogpositioner, the GX 3-Way provides high performancecontrol across a wide range of process applications.Compact actuator design. The multi-spring GX 3-Wayactuator is a compact robust design. The GX 3-Waydesign has been optimized to eliminate complicated3-way actuator sizing procedures - once the valve bodyand port size are selected, the actuator size is fixed.Reliable Actuator Performance. Special actuatordiaphragm material helps reduce common problemssuch as air oxidation, thermal aging, low temperatureembrittlement, and loss of retention (see table 6). Thedouble-sided diaphragm within the actuator helpseliminate mechanical wear-induced failure.Modular design. The design architecture has beenoptimized to maximize the use of common partsacross sizes. The actuator stem and stem connectorare used across all GX 3-Way sizes.4Low lifetime costs. Reduced product complexity, lowparts count, and part commonality all contribute toreduced inventory and maintenance costs.Stable flow control. The flow cavity of the GX 3-Wayvalve body has been engineered to provide stable flowand reduce process variability. This linear stability forboth converging and diverging flow is perfectly suitedfor temperature and pH control applications.Emission Requirements— ENVIRO-SEAL packingsystems provide an improved stem seal to helpprevent the loss of valuable or hazardous process fluid.The GX 3-Way comes standard with ENVIRO-SEAL PTFEpacking. ENVIRO-SEAL graphite ULF packing is alsoavailable for all sizes and is standard on hightemperature constructions.Easy maintenance. The simple screwed seat-ring andone-piece plug and stem design provide easymaintenance. Design simplicity and partscommonality contribute to reduced spares inventory.The integrated DVC2000 and DVC6200 digital valvecontrollers allow easy instrument removal, without a
GX 3-Way Valve and ActuatorD103305X012requirement for tubing disconnection or replacement(fail-down construction).Digital valve controller. The GX 3-Way is available withthe DVC2000 digital valve controller. The DVC2000 iseasy to use, compact, and designed for easymounting. It converts a 4-20 mA input signal into apneumatic output signal, which feeds the control valveactuator. Instrument setup is performed with a pushbutton and LCD interface. This interface is protectedfrom the environment within a sealed enclosure. Theinterface supports multiple languages, includingGerman, French, Italian, Spanish, Chinese, Japanese,Portuguese, Russian, Polish, Czech, Arabic, andEnglish.Intrinsic safety and non-incendive construction isavailable to CSA, FM, ATEX, and IEC standards. Anoptional module provides integrated limit switchesand a position transmitter.Integrated mounting. The DVC2000 and DVC6200digital valve controllers integrally mount to the GX3-Way actuator, eliminating the need for mountingbrackets. The DVC2000 transmits a pneumatic signalProduct Bulletin51.1:GX 3-WayAugust 2017to the actuator casing via an air passage in the yokeleg, causing the valve to stroke (see figure 12). Thiseliminates the need for positioner-to-actuator tubingin the fail-down configuration.The DVC2000 and DVC6200 mounting interfaces areidentical on both sides of the actuator yoke for valvebody sizes DN 25 through DN 100 (NPS 1 through 4).This symmetrical design allows the DVC2000 to beeasily moved from one side of the valve to the otherwithout the need to rotate the actuator.Linkage-less feedback. The DVC2000 and DVC6200digital valve controllers offer as standard anon-contacting valve position feedback system. This isa true linkage-less design, which uses no levers and notouching parts between the valve stem and thepositioner.Additional Accessory selection. The GX 3-Way isavailable with a variety of digital or analog positionersbesides the DVC2000 or DVC6200, as well as solenoidand limit switches. The actuator is also compatiblewith the IEC 60534-6-1 (NAMUR) positioner mountingstandard.5

FIELDVUE DVC2000Digital Valve ControllerThe GX 3-Way is available with a variety of pneumatic(P/P), electro-pneumatic (I/P), and digital valvepositioners, as well as limit switches and solenoids.Table 13 provides the basic features of the positionersoffered with the GX 3-Way actuator.The FIELDVUE DVC2000Digital Valve ControllerThe DVC2000 digital valve controller (figure 18) issimple to use, compact, and designed for the GX3-Way control valve. It converts a 4-20mA input signalinto a pneumatic output signal, which feeds thecontrol valve actuator. Instrument setup is performedwith a pushbutton and LCD interface. This interface isprotected from the environment within an IP66enclosure. Multiple languages are supported with thelocal interface including German, French, Italian,Spanish, Chinese, Japanese, Portuguese, Russian,Polish, Czech, Arabic, and English. Additionally, HARTrcommunication is supported over the 4-20mA loopwiring.The DVC2000 is designed to be integrally mounted tothe GX 3-Way actuator, avoiding the need formounting brackets. The DVC2000 mounts directly toan interface pad on the actuator yoke leg with a secure3-point mounting. An internal passage inside the yokeleg transmits the pneumatic signal to the actuatorcasing, eliminating the need for external tubing (in thefail-down configuration).W8755The high-performance linkage-less position feedbacksystem eliminates physical contact between the valvestem and the digital valve controller or instrument.There are no wearing parts so cycle life is maximized.Additionally, the elimination of levers and linkagesreduces the number of mounting parts and themounting complexity. Digital valve controller orinstrument replacement and maintenance is simplifiedbecause the feedback parts stay connected to theactuator.The DVC2000 is available with an optional modulewhich includes two (2) integral limit switches and astem position transmitter. The limit switches areconfigurable for open and closed valve indication. Theposition transmitter provides a 4-20mA signal for valveposition feedback verification. As an integralcomponent to the instrument, this option moduleavoids the need for difficult-to-mount externalswitches and transmitters.Designed to meet intrinsic safety and non-incendiverequirements, this instrument delivers scalablefunctionality and high performance in a small package.19

Designed to meetintrinsic safety requirements, these positioners offersimple functionality in a small package. (See table 13.)W9713DVC6200 Digital Valve ControllerThe DVC6200 digital valve controller is acommunicating, microprocessor-basedcurrent-to-pneumatic instrument. Using HART orFOUNDATIONt fieldbus communication protocol,access to critical instrument, valve, and processconditions is provided. When used with ValveLinktsoftware, valve diagnostic tests can be run while thevalve is in service to advise you of the performance ofthe entire control valve assembly. Designed to meet abroad range of hazardous area classifications, thisinstrument offers maximum functionality to improveyour process performance.
