New SP2 Series Smart Control Valve Positioners Aid Control of Fluid Processing
BLYTHEWOOD, SC - August 18, 2003 - The new Spirax Sarco SP2 Loop Powered Smart Positioner provides a "smart" approach to pneumatic control, for improved valve performance and efficiency in fluid processing. The SP2 Smart Positioner offers precise valve positioning, critical to accurate and efficient control, by eliminating hysteresis and differential pressure effects and allowing optimum actuator selection. The SP2 reacts rapidly and accurately to system changes, but in the balanced state, it consumes almost no compressed air, significantly reducing utility costs.
Designed to be user friendly, the SP2 includes many programmable functions through menu driven embedded software. An integral keypad and digital display enable simple customization of valve performance to suit the application. The SP2 provides many smart features, including automatic setup and calibration, greatly reducing commissioning costs and eliminating errors. Data logging of valve performance helps predict when valve maintenance is required, while adaptive action helps to compensate for changes in supply air pressure and stem friction. A high-visibility valve position indicator is standard on all SP2 Smart Positioners, as is a digital display of percentage valve travel or incoming controller signal. Additional options include supply and output pressure gauges, travel switches and retransmit of valve position.
The SP2 may be used with any of Spirax Sarco's high performance, linear valves or those from other manufacturers that conform to the IEC 60534-6-2 (NAMUR) mounting standard.
Spirax Sarco is the world leader in the control and efficient use of steam and other industrial fluids.
