Spirax Sarco Inc. (SSI) has released the new SP200 line of electropneumatic smart control valve positioners. The SP200 can be fitted to any of SSI’s pneumatic direct actuators. Installation is simplified by the absence of mechanical linkages between valve stem and positioner and the smart auto-calibration function. Plus, local calibration and parameter setting can be performed through menu-driven software with an integral keypad and a large, LCD alphanumeric data display. Valve commissioning is simplified through an auto-stroke routine and display of programming status, software travel switch status, 4-20mA input signal and valve diagnostics. The tight pressure valve shut-off reduces air consumption, while the adaptive valve control automatically adjusts for changes in air supply pressure, stem friction and more, maintaining accurate control. The compact positioner features single/fail vent action and function with 2-port or 3-port valves. It offers linear, equal percentage and fast opening modes with an output capacity of 5SCFM at 90psig. The SP200 includes: anti-corrosive, die cast aluminium construction; a local LCD indicator; a NAMUR standard mounting kit for attachment to yoke- or pillar-mounted actuators; and an optional pressure gauge block.
