Installation note:

1. The actuator must be on a horizontal line.
2. do not use strength to drive when installation;
3. connected to the valve of the thread must be as the standard of national standard pipe thread;
4. before the installation of the valve and pipe should be kept clean, must not have sundry;
5. level suggested by the valve and pipeline installation, can be installed vertically, but shall not be inverted;
6. clear to ensure thermal insulation pipe and valve, actuator package may not be within the insulation layer. Note: if due to improper installation, working condition of damage caused by the medium is too bad, we only provide paid services.
