MTC-VT Series Valve Temperature Controller
What is Valve temperature Controller?
The Series MTC-VT valve Temperature Controller controls the current position of a valve or damper by accepting a signal from a position indicator. The controls can be programmed for ON/OFF,PID, auto-tuning or manual tuning control methods. For greater design flexibility, the Series MTC-VT accepts thermocouple, RTD, current or voltage inputs. An auto/manual key is located on the front panel in order to toggle between manual operation and automatic operation. The RS-485 serial communications work with Modbus RTU protocol. During normal operation the controller will display the present value (PV), set point value (SV).
Things You Need To Know About Valve Control
Heaters and coolers can be used to control the temperature and the openness of the valve in order to control the flow of the medium. Current and voltage can control the openness of the valve, however,the most direct and economic way to control the openness of the valve is the relay. To control the valve by voltage and current, you can use the MTC-MT series analog output controller. If you tend to use relay for the control output, you have to choose the valve controller MTC-VT Series. The two control outputs are relay output for the forward/reverse running of the
motor to drive the opening and closing of the valve. Control output1 controls the opening of the valve and control output 2 controls the closing of the valve in order to adjust the position of the valve. In order to detect the position of the valve, ,MTC-VT is able to receive «feedback signal» and «no feedback signal».
