electrical valve I/P positioner/ converter
electrical valve positioner
Summary
EPP(HEP) electrical valve positioner will changed electrical signal output by regulating device into gas signal of controller action, and with valve positioning function to overcome stem friction, and to offset balance force caused by dielectric pressure change, then make the valve open corresponds to control signal outputed by regulating device to realize corrective position.
