The model AVP70* receives a DC current signal from control devices and controls pneumatic valves. In addition to this basic function, the model AVP70* has communication capabilities, an automatic configuration program and self-diagnostics functions that will greatly increase productivity and the efficiency of plant operation. Calibration, configuration and self-diagnostics can be performed by using a HART communicator. FEATURES Easy to use . Auto setup The auto-setup function is a fully-automatic configuration program which specifies the actuator and adjusts the zero and span of the valve. The program can be turned on simply from an external switch so that adjustments to the valve can be performed quickly and safely in hazardous areas. Valve diagnostic Following parameters can be monitored by HART communicator or Control Valve Maintenance Support System “ValstaffTM”. . Stick Slip . Total Stroke . Travel Histogram . Cycle Count . Shut-Off Count . Max. Travel Speed . Valve Signature . Full Stroke Test High reliability . Positive seating The positive seating function completely shuts off the valve if the input signal becomes lower than previously set. This in turn enhances the full shut-off capabilities of the valves. . Self-diagnostic The self-diagnostic function provides the user with the ability to check the status of the positioner at any time and to alert in case of failure. Single model for multiple specifications The model AVP70*’ settings can be changed without replacing any parts. A single model can be modified to suit any application. . Input range Configurable to any required range for split range . Flow characteristic Linear, EQ%, Quick opening or custom user characteristics . Actuator type Double or single acting actuator China RoHS This device is used in the Oil & Gas, Petrochemical, Chemical, Pulp & Paper, Food & Beverage, Machinery, Steel/Metal & Mining, and Automobile industries and therefore does not fall under the China RoHS Legislation. If this device is used in semiconductor manufacturing equipment, labeling on the device and documents for the China RoHS may be required.
