DVC digital valve controllers are communicating, microprocessor-based current-to-pneumatic instruments. This will pull the plug to an open position on a PDTC valve. In reply to Alex Quah: You can email me at alex.

My name is Thales Dbc, Many thanks for your valuable feedback regarding this matter: Sullivan and Sons Valves. Many thanks for your 600 answer, I look forward to receiving your comments on this issue. Dvv with 2 year. Suggested a reverse acting relay B if the ZPC needs to be changed to close. 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.

A pneumatic signal is then delivered to a control element to change the process differential pressure toward the set point. Zero pressure to Fisher will retract the stem upwards. This will give full air output to the actuator at 4mA or 0mA and zero air output at 20mA.

Click on the link below see our remanufactured Fisher products flyer: However the actuator is Fisher Open. Thanks Alex for your response. Many thanks In advance Alex for your valuable answer. Give us a rvc today. Fisher Flyer Don’t forget! Again, thanks a lot for sharing your knowlegde and expertise.

It is written on the actuator nameplate Power Fail: Click here to join. The sequence of events dbc go: The DVC has a relay type C.

All of our remanufactured products include a 2 year warranty. How can I attached some pictures in order to ilustrates much better my case? For addition information click on the link. Screenshots show that rvc users are aware of the inverted feedback. This will give zero power failure ZPC of close and pneumatic failure of open to the current valve assembly.

DVC digital vvc controllers are designed to directly replace standard pneumatic and electro-pneumatic valve mounted positioners.

The actual configuration on DVC is: Could you provide me some technical feedback on this point? There is a control valve with Actuator Fisher power fail: I verified the configuration and it was set the Zero Power condition as Valve Close default value. They are trying to match stroke and command to the DVC But there is no positive results.

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. In reply to Thales:. In the event of a loss of power to the DVC, the valve will be open and allow flow through. Join Our Mailing List! We offer significant savings, quick lead times, and friendly service.

These include “E” series globe, Vball, and butterfly valves. I tried to persuade the team without sucess. I am sending some information to your personal mail.

The controllers sense two different pressures and compare the difference between these pressures with an operator-adjusted set point. In reply to Alex Quah:.
