3D Display of Electric Valve:

Installation Precautions:
● Before installing the valve, clean the line of dirt, scale, welding chips, and other foreign material Clean gasket surfaces thoroughly to insure leak-proof joints.
● Verify that the valve breakaway torque is less than the rated output torque of the actuator.
● Any mechanical stops that would interfere with the operation of the actuator must be removed before installation of the actuator, i.e. lever, travel stops, etc.
● The actuator output coupling must be centered with the valve stem to prevent side loading, which causes premature stem packing wear.
● To use the manual override feature (identified on cover label), the override shaft must be pressed down firmly at least 1/4" in order to disengage the motor from the gears. The manual override is not designed to overcome torque in excess of the rated torque of the actuator. Serious damage to the gear system may result from excessive turning force on the manual override.
● This Series actuator may be mounted in any position, i.e. horizontal, upside down. If the conduit entrance points upward, conduit piping must be oriented as to prevent condensation from enteringthe actuator from the conduit pipe.

Installation environment:
● The product can be installed indoor and outdoor, The surrounding environment temperature should be in -30°C~+60°C
● Product is non-explosion-proof production, and the installation must be avoided being in flammable or explosive environment etc.
● The actuator should be in protection box in the environment of long-term with the splash of rain, material and direct sunlight.
● Please reserve space for controller, manual operation.
★ The surrounding environment temperature should be in -30°C~+60°C.

Installed on the valve body:
● Manually operate the actuator to drive the valve, confirm it does not have abnormal situation. Turn the valve in full closed position.
● Assemble the bracket to the valve body.
● Set one end of couplings on valve spindle.
● Turn the electric actuator to full closing position, and insert output-input shaft into the square holes of couplings.
● Set the screw between the electric actuator and bracket.
● Turn actuator by hand shank, confirm that it moves translation, no eccentric, no skew and no overrun.


Cable installation:
● Install wire tubes, The outside diameter of wire tubes should be $9-411. Take measures to proof water. To prevent actuator from flowing into wire tubes water, the actuation position should higher than wire tubes position.
● When installing wire, the outside diameter of wire should be $9-φ11. in case the water flow into actuator interior from line locking, all wire that are not allowed to be used.
● The signal wire should be shielded wire in principle, don't parallel it to power wire.

Special tips:
● Caution: can't connect one actuator parallel with one another, in other words, can't use the same controller contact point to control more than one actuator, otherwise it will cause out of control, motor overheating, product damage, shorter service life.
● If the actuator is installed outdoor, we suggest equipping other protective cover to proof water, stabilize mechanical property, make a longer service life.
