- 1 - 8th edition No. SS2-SVX100-0100 OVERVIEW Smart Valve eXplorer (SVX) models SVX100 and SVX102 are microprocessor-equipped, currentpneumatic smart valve positioner for rotary valves. The SVX receives a DC current signal from control devices and controls pneumatic valves. In addition to this basic function, the SVX has communication capabilities, 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. (model SVX102 only) 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 rotary valve. The program can be turned on simply from an switch so that adjustments to the rotary valve can be performed quickly and safely in hazardous areas. Valve diagnostic (for model SVX102, software version 4.9 or later) Following parameters can be monitored by HART communicator or Control Valve Maintenance Support System “Valstaff”. . Stick Slip . Cycle Count . Total Stroke . Shut-off Count . Travel Histogram . Max. Travel Speed. Flexibility in installation The models SVX100 and SVX102 are available either as a slide lever type or a stroke lever type to facilitate installation on rotary valves. . Slide lever type The SVX can avoid vibration chattering with anti-vibration feedback lever. . Stroke lever type The valve stem can be adjusted with a pipe wrench. (For manual operation) . Direct mounting type The SVX can be installed to NAMUR cylinder actuator without linkage. 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 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 SVX settings can be changed without replacing any parts. A single model can be modified to suit any application. . Flow characteristic: Linear, EQ%, quick opening or custom user characteristics (16 points) . Actuator type: Double or single acting actuator HART communication HART communicator model 375 can be used for calibration, configuration and self-diagnostics.
