Single Acting Positioner Description

The supply and output connections for the SVI FF (Figure 9), located on bottom of the pneumatic
block, are tapped 1⁄4" NPT. Output is toward the front, supply is toward the back. Two pressure
gauges, output on top, supply on bottom, are located on the front of the pneumatic block.
The supply and output connections for the SVI FF High Flow (Figure 10), located on bottom and
leftside of the pneumatic block, are tapped 1⁄2" NPT.
Maximum allowable air supply pressure to the SVI FF varies according to actuator, valve size,
and valve type. See Pressure Drop tables in valve specification sheets to determine the correct
positioner supply pressure. Minimum supply pressure must be 5 psi to 10 psi (.345 bar - .69 bar)
(34.485 - 68.97 kPa) above maximum spring range but cannot exceed the rated actuator
pressure.
