Installation

WARNING
Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before proceeding
with any procedures:
D Always wear protective clothing, gloves, and eyewear to prevent personal injury or property damage.
D Do not remove or uncouple the actuator from the valve while the actuator is still pressurized.
D The valve will need to be locked at its present position. If you cannot safely lock the valve in position until this procedure
is complete, do not proceed with this procedure.
D After the valve has been safely locked in position, 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 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.
1. Lock Valve in Place
1.1 Ensure the mounting kit for the replacement DVC2000 is compatible with the valve assembly. Do not proceed
with this procedure until you have obtained a mounting kit compatible with the replacement DVC2000 and the
control valve assembly.
1.2 Block the valve into position either with a handwheel or other mechanism. If you cannot safely lock the valve in
position until this procedure is complete, do not proceed with this procedure.
1.3 Disconnect the operating lines that provide air pressure to the actuator. Bleed any extra air that may be built up in
the instrument. Please note which air connections go to the actuator and which come from supply for future
reassembly.
1.4 Determine and record the following parameters:
D Feedback Connection: The magnetic array type that will be used with the replacement digital valve controller.
Note
This procedure only supports feedback connections using linear sliding-stem arrays. Do not proceed if you are not using a linear
sliding-stem array.
D Travel Sensor Motion: States whether increasing drive signal causes the magnetic assembly to move toward the
top of the instrument or away from the top of the instrument.
D Air (Closes/Opens): States whether adding air opens or closes the valve.
D Actual Travel: The measured distance from the closed position to the fully open position of the valve.
2. Configure Replacement Digital Valve Controller Prior to Installation
2.1 Open ValveLink software and connect to the replacement digital valve controller.
