Overview
DKZ straight stroke electric actuator is the EU (execution unit) in automatic control system, which receives control signals of upper regulator or DCS system, outputs linear thrust, and adjusts procedure parameter. It is mainly used along with straight stroke regulating valve and sleeve valve.
The control modes of DKZ electric actuator are overall electronic type and separated type which has locator and electric actuator.
Operating Principle
DKS electric actuator is a position servomechanism which adopts two-phase alternating current servomotor as motive force.
