- 1 - 7th edition No. SS2-8310-0400 OVERVIEW The Pneumatic Valve Positioners (VPE) are designed specifically for small actuators for the CV3000 Alphaplus Series valves, the CV3000 Series valves, NEW10 Series valves, and Small Flow vavles to improve characteristics and response of control valves as well as to minimize the effect of changes in fluid pressures. FEATURES 1) The VPE is compact and can be readily installed in small actuators. 2) All of the major components are housed in the casing and purged with bleeding air, there by preventing corrosion caused by adverse atmosphere. 3) The VPE provides an air booster mechanism. Although compact, the VPE allows a rapid response speed which is comparable with that of a large positioner. 4) The VPE can be effectively used when the controller signal span and the actuator spring span do not mutually conform, so that the valve position can be controlled in direct conformity with the controller signal.
