instructions
The EP1000 electric pneumatic valve positioner is used in conjunction with a control penalty to convert the signal output by the regulator into a pneumatic signal that drives the regulating valve. It overcomes the friction between the packing box and the valve stem, overcomes the unbalanced force of the medium pressure difference on the regulating valve core, and improves the valve's operating speed. It can achieve range control (segment signal), change the valve's operating mode, and control various types of pneumatic actuators with non-standard operating pressure.
