SP500 Electropneumatic Smart Positioner

Product Technical Information

ACTUATORS

Product Description

Positioners are fitted to a pneumatically actuated control valve in order to maximise its operational efficiency by guaranteeing a set valve position relative to the input control signal. 

 

The SP500 smart valve positioner is loop powered from a 4 - 20 mA input signal to provide accurate adaptive positional control of pneumatic actuated linear and quarter turn valves.

Precise control is maintained through valve position feedback that automatically varies the pneumatic output pressure to overcome the effects of stem friction and flow forces to maintain desired valve position.

Indication of valve position is provided through a continuous digital display of % travel. Valve position feedback is retrieved by means of a non contact technology based on Hall effect.

The pneumatics are based on piezovalve technology - Therefore, high resolution, high reliability, vibration insensitivity and extremely low air consumption is guaranteed at steady state.

The SP500 includes many smart functions that can be fully programmed through menu driven software using an integral keypad and LCD alphanumeric data. Valve commissioning is simplified through an autostroke routine and display of programming status, software travel switch status, mA input signal and valve diagnostics data.

Moreover, the absence of mechanical linkages between valve stem and positioner, drastically simplifies the mounting procedure and reduces the time required.

The SP500 is supplied with a NAMUR standard mounting kit for attachment to yoke or pillar mounted actuators. For quarter turn valves, a mounting kit compliant to VDI/VDE 3845 is supplied.

The SP500 smart valve positioner supports optional expansion to include the HART® communication protocol, enabling complete configuration using a PC or handheld device.
