Quarter‐Turn Rotary Actuators
The DVC6215 feedback unit 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 2‐18.
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 must be parallel
to the channel on the back of the DVC6215 housing, as shown in figure 2‐19.
3. Install the mounting bracket on the actuator.
4. Attach the feedback unit to the mounting bracket using the 4 mounting bolts, as shown in figure 2‐18.
5. Check for clearance between the magnet assembly and the DVC6215 feedback slot.
6. Install tubing between the actuator casing and the appropriate DVC6215 pneumatic output port.
