Physical and Operational Description

SVI II ESD is a smart electro-pneumatic positioner that receives a 4 - 20 mA electrical position
setpoint signal from controller and compares it with valve position feedback sensor. The
difference between position setpoint and position feedback is analyzed by position control
algorithm that sets a servo signal to I/P converter. I/P output pressure is amplified by a
pneumatic relay driving the actuator. Once the error between setpoint and the valve position
feedback is within range, no further correction is applied to the servo signal in order to
maintain valve position.

Local explosion proof LCD/Buttons (if equipped) display provides configuration or calibration
capabilities in all operating environments. The limit switch

⁄

transmitter options board provides

software configurable contact outputs, and analog (4 - 20 mA) position feedback.

SVI II ESD is housed in an industrial, tough, weatherproof, corrosion resistant aluminum
housing designed to operate in hazardous areas. Electrical connections are through two 1/2”
NPT F conduit entries. Pneumatic connections are through two or three ¼” NPT F ports.
