Precautions for storage, installation and use
1. Both ends of the valve path must be covered with protective cover, stored in a dry, ventilated room, such as long-term storage should be regularly checked to prevent corrosion;
2. Do not remove the dust cover before installation of the valve, so that there is no dirt in the valve;
3. Remove the dust cover during installation, and blow the pipeline clean with air first to avoid dirt into the valve cavity;
4. After 12-14 hours every day, the valve disc should be closed in time when the system does not work to avoid long-term compression of the spring and reduce the reliability of long-term use of the valve.
