Actuator Options:
1. Which voltage of the electric actuator?
DC24V, AC24V, AC110V, AC220V
AC380V can be customized and DC12V is available for some smaller torque of actuator.
2. What is the actuation time for electric actuator?
It depends on the torque of actuator.
The detailed timing would be as the following:
·COVNA-05(50Nm)-20 seconds
·COVNA-10(100Nm)/COVNA-16(160Nm)-25 seconds
·COVNA-30(300Nm)/COVNA-60(600Nm)-60 seconds
·COVNA-125(125Nm)/COVNA-250(2500Nm)/COVNA-400(4000Nm)-100 seconds.
3. Can the actuation time be faster?
Electric actuator can be customized the quick actuation gear,
the soonest actuation time can be reach 10 seconds to open and close.
4. What type of electric actuator you provide?
ON/OFF type, Regulation type and Intelligent type.
5. What is the difference from ON/OFF type, Regulation type and Intelligent type?
1)ON/OFF type
ON/OFF type is fully open and fully closed.
2)Regulation type
1.With input/output signal:4-20mA or 0-10V;
2.Opening position of valve can be adjusted by signal;
3.Available for PLC system.
3)Intelligent type
1.With input/output signal:4-20mA or 0-10V;
2.Opening position of valve can be adjusted by signal;
3.Available for PLC system.
4.With display screen to acheieve site control.
6. Can this electric valve be resettable (normally open / closed) automatically when power is removed?
Our regular electric actuator can't be resettable automatically while power-off.
But it can go to the multiturn electric actuator model with the extra electrical storage device along,
which acheieve the valves can be automatic reset(normally closed) while power failure.
7. Have the electric actuator had the presence of limit switches (contact about the position of the cut-off device)?
Yes, there is the position indicator on the top of actuator.
The open/closed status can be checked visually.
8. Which type of protection class of this electric actuator?
IP65, IP68, Explosion proof.
9.Is there any manual override of electric valve?
Yes, every electric valve includes the manual override.
You can open/close
10. Have the electric valve had the limiting operating time?
Electric haven't had the limiting operating time.
It can be working for 99 hours continually without getting heating.
