The name of Appendix

Function

Type

Servo amplifier

Accompanied  with DKJ, DKZ etc electric actuators which request powerful control.

Because the DCS series computer system can only emit 4-20mA week electrical signal,       however the DKJ, DKZ series actuators can only be controlled by powerful electricity. So require that use the servo amplifier to amplify the 4-20mA week electrical signal to powerful electrical signal in order to fulfill the control actuator.          

If add the function of the amplifier to actuator then the actuator will become improved DKJ, DKZ series electric actuator, in this way this kind of actuator can be used without amplifier.

Operator

It is DKJ, DKZ etc electric actuators’ appendix, in the control-room.

There are two functions: 1. when the DCS system appear failure or when the system is overhauled, using it’s manual function to control the electric actuator at site.

2. Feedback the signal of position of valve in order to tobserve the opening degree of  valve at site in the control room.

Portable

Ball-joint

scientific name: more directions ball-joint. The link rod of  valve and the output shaft are linked with a pair of ball-joint, in order to the losses of torque is lowest.
