Quarter-Turn Electric Valve Actuator

Summary
The electric actuators we manufactured are the products by using the introduced advanced technology from BERNARD Company of France.
It has various kinds of protection function and control mode. It can be divided into the quarter-turn series, linear-turn series and multi- turn series. There are more than hundred kinds of specifications. Its control main board is continuously upgrading and updating and the new products appear rapidly in order to satisfy the needs of modern industrialization.
The electric actuator has already widely applied in the large and medium-sized project which is the newly built and was highly appraised by users.
At the same time, we also accumulate rich technology and scene experiences in the process of updating and upgrading DKJ or other actuators to the introduced series.
The main technical parameters of the electric actuator
The following technical parameters are mainly applied to the proportional modulating type electric actuator. Item1\2\3\4\5and 6 are not suitable for the remote-control type electric actuator and switch type electric actuator.
1. The input signal: 4--20mA DC
2. The input resistance: 250 ohm
3. Input passage: 14. Basic error: 1%, 2.5%
5. Deviation: 1.5%
6. Deadline: 0.5%--3% continuously adjustable
(according to the indication of system)
7. Damping characteristic: No-oscillating
8. Power supply: Three-phase 380V~50Hz, single-phase 220V~50Hz for selected
9. Working conditions: Temperature: Integral-type -10-- +55, separate-type -25 -- +70
Humidity: ≤ 85%The surrounding air does not have the corrosive elements
10. Protection rank: It conforms to the IEC145 IP65 standards. (Excluding the separate-type GAMX with waterproofing and dustproof functions fixed in rooms), bus type and intelligent type IP67.
11. The cut-off signal protection: It can be divided into all-on, all-off and home position according to your instructions.
Generally it is set into the home position when it is manufactured.
