FAQ

Q:Which voltage of the electric actuator?
A: DC24V, AC24V, AC110V, AC220V
AC380V can be customized and DC12V is available for some smaller torque of actuator.

Q: What is the actuation time for electric actuator?
A: 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.

Q: Can the actuation time be faster?
A: Electric actuator can be customized the quick actuation gear,
the soonest actuation time can be reach 10 seconds to open and close.

Q: What type of electric actuator you provide?
A: ON/OFF type, Regulation type and Intelligent type.

Q: What is the difference from ON/OFF type, Regulation type and Intelligent type?
A: 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.

Q: Can this electric valve be resettable (normally open / closed) automatically when power is removed?
A: 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.

Q: Have the electric actuator had the presence of limit switches (contact about the position of the cut-off device)?
A: Yes, there is the position indicator on the top of actuator.
The open/closed status can be checked visually.

Q: Which type of protection class of this electric actuator?
A: IP65, IP68, Explosion proof.

Q. Is there any manual override of electric valve?
A: Yes, every electric valve includes the manual override.
You can open/close

Q:Have the electric valve had the limiting operating time?
A: Electric haven't had the limiting operating time.
It can be working for 99 hours continually without getting heating.
