DVC6200 Digital Valve Controllers

January 2014

Quarter‐Turn Rotary Actuators

The DVC6200 digital valve controller can be mounted to any quarter‐turn rotary actuator, as well as those that comply

with the NAMUR guidelines. A mounting bracket and associated hardware are required. Refer to figure 12.

1. Isolate the control valve from the process line pressure and release pressure from both sides of the valve body. Shut

off all pressure lines to the actuator, releasing all pressure from the actuator. Use lock‐out procedures to be sure

that the above measures stay in effect while you work on the equipment.

2. Attach the magnet assembly to the actuator shaft. At mid‐travel, the flats on the magnet assembly should be

approximately parallel to the channel on the back of the DVC6200 housing, as shown in figure 13.

1 THIS EXAMPLE SHOWS AN ACTUATOR WITH 90_ TRAVEL. ON AN ACTUATOR THAT HAS LESS THAN 90_ TRAVEL THE MAGNET ASSEMBLY MAY NOT BE

PARALLEL AT THE MID-TRAVEL POINT. TO VERIFY THE MAGNET ASSEMBLY POSITION IS IN WORKING RANGE, CONFIRM TRAVEL COUNTS ARE WITHIN THE

EXPECTED RANGE OF 175-3800 USING VALVELINK SOFTWARE OR A FIELD COMMUNICATOR.

3. Install the mounting bracket on the actuator.

4. Attach the digital valve controller to the mounting bracket using the 4 mounting bolts, as shown in figure 12.

5. Check for clearance between the magnet assembly and the DVC6200 feedback slot.

6. For remote mount applications, proceed to page 13 for DVC6205 base unit mounting. Otherwise, proceed to

Step 2—Connect the Pneumatic Tubing on page 15.
