DVC digital valve controllers are designed to directly replace standard pneumatic and electro-pneumatic valve mounted positioners. Click here to join. The controllers sense two different pressures and compare the difference dgc these pressures with an operator-adjusted set point. DVC digital valve controllers are communicating, microprocessor-based current-to-pneumatic instruments.
The DVC has a relay type C.
For addition information click on the link. I verified the configuration and it was set the Zero Power condition as Valve Close default value. Again, thanks a lot for sharing your knowlegde and expertise. Many thanks In advance Alex for your valuable answer. In reply to Alex Quah:.
There is a control valve with Actuator Fisher power fail: 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. We offer significant savings, quick lead times, and friendly service. They are trying to match stroke and command to the DVC But there is no positive results.
Become a member of this Emerson Exchange group. Suggested a reverse acting relay B if the ZPC needs to be changed to close.
How can I attached some pictures in order to ilustrates much better my case?

The actual configuration on DVC is: In reply to Thales: This will give full air output to the actuator at 4mA or 0mA and zero air output at 20mA. I tried to persuade the team without sucess. This will pull the plug to an open position on a PDTC valve. All of our remanufactured products include a 2 year warranty.
Hi Thales, Nice to meet you. This will give zero power failure ZPC of close and pneumatic failure of open to the current valve assembly. In reply to Thales:. In the event of a loss of power to the DVC, the valve will be open and allow flow through.

Could you provide me some technical feedback on this point? Sullivan and Sons, Inc.
Sullivan and Sons Valves. A pneumatic signal is then delivered to a control element to change the process differential pressure toward the set point.

In addition to the traditional function of converting an input current signal to a pneumatic output pressure, the DVC digital valve controller communicate via HART protocol. You can email me at alex.
The sequence of events will go: My name is Thales Camargo, Many thanks for your valuable feedback regarding this matter: 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 dvcc.
