1, Introduction of foreign advanced design, high reliability, small volume, light weight, etc.
2, Magnetoelectric component part adopts new coil structure, reliable, good stability and linear.
3, In addition to the explosion-proof junction box, the scene of the dangerous area can be adjusted and open the shell and cover maintenance and repair.
4, Range, zero adjustment knob by hand wheel, easy to adjust, and with a locking device.
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.
