DVC2000 Digital Valve Controller
Installation
Note
The DVC2000 is not designed to
correct for significant stem rotation on
2
sliding-stem actuators.
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 to avoid
personal injury or property damage.
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 Vent the pneumatic actuator
loading pressure and relieve any
actuator spring precompression.
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.
