6.1.1 Notes for indoor installation
To install it where there is any explosive gas, you need to order an explosion-proof actuator;
To install it where it may be flooded or outdoors, please notify us in advance;
Please reserve maintenance spaces for wiring, manual operation and others;
6.1.2 Notes for outdoor installation
In order to avoid rain, direct sunlight and other problems, you need to mount a protective cover or select a protection class above IP67;
Please reserve maintenance spaces for wiring, manual operation and others;
6.1.3 Ambient temperature
The ambient temperature range is from -20ºC to + 70ºC;
When the ambient temperature is below 0ºC, please mount a dehumidifying heater in the machine;
6.1.4 Fluid temperature conditions: when it works with a valve, the fluid heat may be transmitted to its body whose temperature may rise; when the fluid is in a high-temperature sate, special treatment should be provided for the bracket connected to the valve.
Standard bracket: bracket for a fluid temperature below +65ºC or without bracket; Medium temperature bracket: bracket for a fluid temperature above + 100ºC and below +180ºC;
High temperature bracket: bracket for a fluid temperature above + 180ºC.
6.2 Connection to the valve
The flange mounting hole size at the actuator bottom is in line with the standard ISOS211. If the valve's installing size is not in line with it, please design a bracket or adapter plate separately.
6.2.2 The actuator is connected to the valve by a removable drive shaft sleeve on it. The drive shaft sleeve is provided as a solid piece, and you should first screw out two fastening screws counterclockwise with a wrench and then eject the driving shaft sleeve with two ejection screws.
Note: The drive shaft sleeve can be designed and manufactured separately by users based on its function requirements, and it can be designed into round, square or other shapes for output (The concentricity of hole and outer circle must be ensured in processing).
