Installation
Note
The DVC2000 is not designed to correct for significant stem rotation on sliding stem actuators.
WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before mounting
the DVC2000 digital valve controller:
D Always wear protective clothing, gloves, and eyewear when performing any installation procedures.
D Do not remove the actuator from the valve while the valve is still pressurized.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the control valve.
D Use bypass valves or completely shut off the process to isolate the control valve from process pressure. Relieve process
pressure from both sides of the control valve.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression so the actuator is not
applying force to the valve stem; this will allow for the safe removal of the stem connector.
WARNING
This product is intended for a specific range of application specifications, found in the Specifications table on page 29.
Incorrect configuration of a positioning instrument could result in the malfunction of the product, property damage or
personal injury.
Note
Refer to Hazardous Area Approvals and Special Instructions for “Safe Use" and Installations in Hazardous Locations,
on page 33, for approval specific safe use and installation information.
Valve / Actuator Mounting
If ordered as a part of a control valve assembly, the factory will mount the digital valve controller on the actuator and
calibrate the instrument. If you purchased the digital valve controller separately, you will need a mounting kit to
mount the digital valve controller on the actuator. The following procedures are general guidelines you should
consider when mounting the digital valve controller. See the instructions that come with the mounting kit for detailed
information on mounting the digital valve controller to a specific actuator model.
