Actuator Mounting

Note:

        Prior to mounting,the part-turn actuator must be checked for any damage

        Damaged parts must be replaced by original spare parts

 Mounting ia most easily done with the valve shaft pointing vertically upward.But mounting is also  possible in any other position ;the actuator may be mounted in any position.

 The QT-series electric actuators are supplied with a female drive output.the ISO5211 bolt patterns  are provided for actuator mounting.The actuator drive bush is removable for ease of machining.

 It is mandatory for the actuator to be firmly secured to be a sturdy mounting bracket or directly  mounted to be valves' ISO mounting pad.High tensile bolts or studs with spring locking washers  must be used.

 The valve outpot shaft must be in lined with the actuator output drive to avoid side-loading the  shaft .To avoid backlash,flexibility in the mounting bracket or mounting should not be allowed. 

We use high quality plywood wooden case packing which avoid fumigation.It have good cushioning performance,

high strength,and corrosion resistance.The use of foam film cover the valve better to protect the valve body and

fixing wooden cases is the final step.
