First, Product Overview
EP4000 electricity - gas valve positioner is made in introducing foreign technology.
it with the regulator, constitute a closed loop control circuit. The controller output
Electrical signal conversion to drive the regulator gas signal, at the same time,
according to the control valve to open for position feedback, the regulator can correct
positioning.
