Mount a FIELDVUE DVC6200 to a Fisher sliding stem valve


Welcome to the Fieldvue hints series
of videos. In this video, we’re going to mount a DVC6200 on a sliding stem valve
assembly. Before we begin, we urge you to read and
follow all directions in the included installation instructions. If you do not
have these instructions please reference our QuickStart guide or the instruction
manual online at the web address at the bottom of the screen. Before performing
any maintenance operations, always wear protective clothing, gloves, and eye wear.
Please follow all site requirements for safety. For the mounting kit it’s a good idea to
do some sub assemblies ahead of time. First we have a connector arm and
extension arm and the feedback array we want to put these together and just get
the screws snug. We don’t want to over tighten them. Another sub assembly that
can be done ahead of time is to add o-ring x’ to the three bolts which hold
the DVC6200 onto the mounting bracket. The o-rings hold the bolts in
place and keep them from falling out. Install the o-rings just about a quarter
of an inch on to the bolts. Now before we can uncouple the actuator, we need to
take some of the actuator to load off the plug because this is a 667
Fisher actuator. It is spring closed. We’re going to add some air to the
actuator and make sure the valve plug moves up off the seat. Once it’s off the
seat it will overcome the force of the spring and balance it with air pressure. We’re going to install the connector arm
and then check our adjustment. Do not tighten the coupling bolts very tight
because we have to adjust the feedback array in three planes. Now to find the
proper spot for the array we’re going to use our plastic alignment template.
The plastic alignment template goes on to the mounting bracket. We’ve got the
mounting bracket attached. Next install the template on the mounting bracket and
verify that we have the array in the proper location for its side-to-side
adjustment. This looks pretty good. Also this is a spring down actuator so we’re
going to take note of this for later. On when we adjust the Ray and it’s up and
down plane we can remove the bracket and tighten the two coupling bolts. Now that
we have this aligned from side to side we’ve already adjusted from side to side
now we want to do the up-and-down in front to back.
I turn this around so you can see it a little better. We’ll take the Philips
head screwdriver and we’ll tighten it up so that the
bracket is nice and square. Next we’ll bring the extension arm and bring it
right to the back of the template. Notice, I’m not forcing a Lima template forward
it’s nice and flush with the mounting bracket. Now what I want to do is make
sure the bottom white line in the array is adjusted above the white line on the
adjustment template or the drawing on the template. I’ll loosen these two
screws and move the array into the proper location. Now go back and ensure that all four
screws are tightened appropriately. I’m going to stroke the valve and make sure
that it stays within the white lines. We start with this at the bottom I’m going
to give it full air and notice that we’re within the white lines of the
array we have the array in the proper location remove the air from the
actuator the next step is to attach the DVC6200
to the mounting bracket the three bolts that we put the o-ring on are used for
this now we’re looking down at the array on the backside of the DVC6200 verify
there’s a nice equal spacing in between the array and the channel on the back of
the unit. We’re going to stroke the valve up and down and we’re going to make sure
that we do not have any clearance or interference issues. We should also check
from the side the DVC6200 has a Hall effect sensor right here in the back and
you can see it in this area. I’m going to make sure the sensor lines up and we
don’t go outside the white lines on the array with valve travel. The Hall effect
sensor is in the same location as a white line you saw on the plastic
template. We’re going to stroke the valve all the way open and closed making sure
that we stay within the white lines. You can see we could make an adjustment if
we need to but it looks like we have the array in the proper location. We have now successfully mounted the DVC6200 to the sliding stem valve assembly.
