First, Product Overview

EPP1000 series electrical and gas valve positioner is the function of adjusting device of  the output electric signal into drive regulator action gas signal, and has the function of
 the valve positioning, is overcome stem friction, offset the pressure change of modulated  medium of unbalanced force, so that the valve opening corresponding to the adjusting
 device output signal, realize the correct positioning. Due to the positioning equipment  explosion-proof structure, it can be used in explosive place.
