Features (continued)
Electric and Pneumatic
 Two End Connection Styles-- The D3 control valve is
available in both CL900 screwed-end and CL600 RF
flanged construction.
 Two Modes of Actuation-- Pneumatic or electric
actuation is available.
 Live-loaded P acking System--The packing system
provides an improved stem seal to help prevent the
loss of valuable or hazardous process fluids or gases.
It features ENVIRO-SEALt packing technology to
provide reduced packing maintenance and
excellent emissions control.
 Rugged Trim Design--The pinned and guided
plug/stem assembly is field-proven and easy to
maintain.
 Severe Service Capability with Tungsten Carbide
Trim--D3 valves are available with tungsten carbide
trim for erosive service. Fisher tungsten carbide trim
is designed specifically for sev ere service
applications in the oil and gas industry. Durable
tungsten carbide trim may benefit your application
by wearing better and lasting longer.
 Easy Maintenance--The hammer nut bonnet/body
joint allows repair or maintenance with a minimum
of tools, without removing the valve body from the
piping system. The seat ring can be removed with a
standard hex socket.
 Integral Bonnet Flange-- The bonnet has an integral
flange, retained by a hammer nut, making the
bonnet-to-body connection. This eliminates use of
snap rings, which can be subject to possible failure
in sour service or in atmospheric corrosion.
 Application Flexibility--A selection of end
connections, trim materials, and flow capacities
allows the D3 to be used in a broad range of
applications, including sour service.
 NACE MR0175/ISO 15156 Service-Ready--The
standard D3 FloPro trim, valve body, and bonnet
meet the metallurgical requirements of NACE
MR0175/ISO 15156.
Electric
 Low Power Consumption-- The Fisher easy-Drive
electric actuator operates with 12 or 24VDC and
less than 0.1 watt hours per operation, using
Modbus,4-20mA,1-5VDC,ordrycontactcontrol
signals.
 Low Temperature-- Theeasy-Driveelectricactuator
design allow use in ambient temperatures as low as
-20C(-4F) without use of a heater.
 Easy Installation--The compact design allows
installation where space is a premium. Fisher
easy-Drive calibrates by simply opening and closing
the valve.
 Remote Monitoring and Configuration-- Loss of
signal position is programmable over Modbus.
Pneumatic
 Low Temperature Materials--Valve c onstruction

 Field-Reversible Actuator--The D3 pneumatic
actuator can be field-converted from
spring-to-close to spring-to-open action.
