Intelligent valve positioner AVP300 series receives current signals and controls pneumatic valves
Intelligent Valve positioner 300 series is an electro-pneumatic intelligent valve positioner. The 300 series receives the DC current signal from the control device and controls the pneumatic valve. In addition to the basic functions, the 300 Series also has communication functions, automatic Settings and self-diagnostics, which greatly increase productivity and efficiency.
The automatic setting function is a fully automatic configuration program that specifies the actuator and adjusts the zero point and range of the valve. You can easily open the program with an external switch, so valve adjustments can be performed quickly and safely, even in dangerous areas.
Model AVP301 has a valve opening signal transmission that can transmit 4-20 mA DC signals. If the input signal is lower than the pre-set value, the valve tight seal function will completely close the valve. This increases the valve's ability to close completely. Model AVP302 has HART communication protocol. The self-diagnostic function checks the status of the locator at any time and alerts in case of failure. You can change the Settings of the 300 Series without replacing any parts. Individual models can be modified for any purpose.
