The function optionally installed

1. Heating and dehumidification device

2. 4-20mA, 0-10V, 1-5V intelligently regulate type

Please connect electric actuator and power line separately. Be sure not control several electric actuator with one point in order to avoid getting out of control and over-hot.

Product production:

The POLOVO valve electric actuator series compared with similar products with its excellent performance and peerless advantages. It owns small volume, beautiful appearance, characteristics of special design and endurable operation, resilient wear resistant and not easy to damage.

Small volume: the volume is just 35% of same kind;

Be portable: the weight is just 1/3 of same kind;

Beautiful appearance: die casting aluminum alloy enclosure, fine and evenly, reducing electromagnetic disturbance.

Powerful function: switch type, proportionally type, potentiometer type intelligently type, it has all kinds of signal output type you wish for;

Wear-resistance: the worm gear and worm perfect combination, the harmonious linkage, worm gear output axis integration design effectively avoids gap connection. making the transmission precision higher.

Using simply: don’t need point-check, add-oil, owns performance of waterproof and antirust, could be installed at any angle.

Multiple Protection: electric position-limiting, mechanical position-limiting, overheat protection, overload protection, dehumidify production.

Many kinds of speed: 5s, 8s, 15s, 30s, 50s, 100s etc;

Numerical control adjustable: highly intelligently controlling module, digital setting, digital regulating, self-diagnosis, highly accurate, the localizer is not required. Automatic-control, many functions on one machine;

Safety guarantee: has passed AC1500V pressure testing, H grade of highly insulated electric machine, which guarantees the operation safety;

Supporting simple: adopting single-phase power, three phase power, DC power, external circuit is simple.

Installation:

Product could be installed indoor, outdoor and underground.

Noted items:

The common product could not be installed in the room full of explosive air unless explosion-proof product;

If installed at certain place having water or splashed material, operator is supposed to install the protection cover additionally for covering complete-machine safely;

Operator should save necessary space needed by manual wire-in operation in advance;

Please installing protected cover above complete-machine

additionally in order to avoid rain or sunshine which accelerates aging of components.

Connection with valve:

1. Manually rotate valve and ascertain that there is normal phenomenon,

then rotate valve to wholly-closed position.

2. Lightly fasten the support onto valve with screw.

3. Slip the coupling over valve-bar of valve.

4. Rotate electric appliance to wholly-closed position and insert output axle

of electric appliance into coupling.

5. Lightly fasten electric appliance onto support with screw. ( Because of the gap we can not avoid during the mechanical device, sometimes the screw will not to aim at the jack,that was the normal condition. At that time, we just turn the manual handle execution to solve it. )

6. Tighten every screw on support,the installation will be finished.
