The controllers sense two different pressures and compare the difference between these pressures with an operator-adjusted set point. This will pull the plug to an open position on a PDTC dvf. Sullivan and Sons, Inc. Remanufactured with 2 year. It is written on the actuator nameplate Power Fail: Many thanks for your valuable answer, I look forward to receiving your comments on this issue.
DVC digital valve controllers are communicating, microprocessor-based current-to-pneumatic instruments. Again, thanks a lot for sharing your knowlegde and expertise.
I tried to persuade the team without sucess. Screenshots show that the users are aware of the inverted feedback. Mentioned that the configuration on the handheld is not an option, it is for the user to let the DVC know how the valve and actuator has been set up.
How can I attached some pictures in order to ilustrates much better my case?

In reply to Thales:. Zero pressure to Fisher will retract the stem upwards. Give us a call today. As I do not have information on the relay type of the DVC on your site, it is difficult for me to say what will happen on your end. However dgc actuator is Fisher Open.
There is a control valve with Actuator Fisher power fail: Thanks Alex for your response.

The sequence of events will go: You can email me at alex. In the event of a loss of power to the DVC, the valve will be open and allow flow through.
This will give full air output to the actuator at 4mA or 0mA and zero air output at 20mA. Many thanks In advance Alex for your valuable answer.
This will give zero power failure ZPC of close and pneumatic failure of open to the current valve assembly. I am sending some information to your personal 6001.

DVC digital valve controllers are designed to directly replace standard pneumatic and electro-pneumatic valve mounted positioners. In addition to the traditional function of converting an input current signal to a pneumatic output pressure, the DVC digital valve dcc communicate via HART protocol.
In reply to Alex Quah:. I verified the configuration and it was set the Zero Power condition as Valve Close default value. Suggested a reverse acting relay B if the ZPC needs to be changed to close.
