Valve Positioner features adaptive valve control.

Press Release Summary:

Able to work with 2- or 3-port valves, SP200 electropneumatic smart control valve positioners offer single/fail vent action. Absence of mechanical linkages between valve stem and positioner, along with smart auto-calibration function, facilitates installation. Local calibration and parameter setting can be performed through menu-driven software with integral keypad and alphanumeric data LCD. Valve commissioning is facilitated via auto-stroke routine and display.

SSI Introduces Smart Control Valve Positioner

BLYTHEWOOD, SC-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.

The compact positioner marks a new standard in ease of use with simpler installation and commissioning, adaptive valve control and smarter functions. 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 ensures cost savings by reducing air consumption, while the adaptive valve control automatically adjusts for changes in air supply pressure, stem friction and more, maintaining accurate control. Plus, the Hall effect, non-contact feedback of valve position increases accuracy and eliminates wear.

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 5 SCFM (8.5 Nm3/h) at 90 psig (6 barg). The SP200 includes: anti-corrosive, die cast aluminum construction; a local LCD indicator; a NAMUR standard mounting kit for attachment to yoke- or pillar-mounted actuators; and an optional pressure gauge block. The positioner is dust tight and resistant to water jets with an IP65 protection rating and compliant with EMC standard 89/336EC.
