Description

The Fisher D3 with easy­Drive electric actuator technology (figure 1) is a globe valve with electric actuator specifically
designed for upstream, low power applications. The easy­Drive operates with 12 or 24VDC in either on/off or
Positioning configurations.
The on/off configuration has 2 different states; opened or closed, which are ideal for dump or snap acting applications.
The Positioning configuration extends the functionality to intermediate positions for flow and pressure control
applications.

Specifications

Table 1 lists specifications for the D3 control valve. Some of the specifications for a given control valve as it originally
comes from the factory are stamped on a nameplate located on the lower actuator housing.

Installation

WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
To avoid personal injury or property damage caused by bursting of pressure‐retaining parts or by uncontrolled process
fluid, be certain the service conditions do not exceed the limits shown on the valve nameplate and in table 1. Use
pressure‐relieving devices required by government or accepted industry codes and good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
WARNING
For explosion­proof applications, ensure the actuator cover is properly bolted before applying power to the actuator.
Personal injury or property damage may result from fire or explosion if power is applied to the actuator with the cover
removed in a hazardous area.
For explosion‐proof applications, install rigid metal conduit and a conduit seal no more than 457 mm (18 inches) from the
actuator. Personal injury or property damage may result from explosion if the seal is not installed.
Select wiring and/or cable glands that are rated for the environment of use (such as hazardous area, ingress protection, and
temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage
from fire or explosion.
