Introduction to Installation and Maintenance of Electric Sealed Valves

Pre-installation Preparation: Prior to installing the electric shut-off valve, relevant preparatory steps must be taken. This includes inspecting the valve and electric actuator for any damage, confirming the valve's opening and flow direction, and preparing the necessary installation tools and materials.

2. Installation Location Selection: Choose a suitable location for the electric sealed valve installation. Consider locations with good ventilation, no vibrations, and no corrosive media, taking into account operational convenience and maintenance requirements.

3. Installation: Mount the electric sealed valve on an appropriate bracket or base, using the appropriate bolts and nuts for securing. Ensure the valve is firmly installed and will not loosen or tilt.

4. Pipeline Connection: Connect the electric shut-off valve to the pipeline using the appropriate sealing materials and fittings, based on the valve and pipe connection method. Ensure the connection is sealed reliably to prevent medium leakage.

5. Electrical Wiring: Perform electrical wiring according to the requirements of the electric actuator. Ensure the wiring of power supply and control signals is accurate and reliable to guarantee the normal control and operation of the valve.

6. Start-Up and Commissioning: After installation, perform the start-up and debugging of the valve. Through operation of the control system, test the normalcy of the valve's opening and closing actions, and verify the accuracy of the electric actuator's operating status and feedback signals.

7. Regular Inspections and Maintenance: Conduct regular checks on the operational status and performance of electric shut-off valves, observing for any anomalies or malfunctions. Regularly clean the valves and electric actuators to ensure their surfaces are clean and free from dirt and corrosion.

8. Lubrication Maintenance: Conduct lubrication maintenance according to the requirements of valves and electric actuators. Regularly apply a sufficient amount of lubricating oil or grease to the valve bearings and transmission parts to ensure their normal operation.

9. Regular Calibration: As needed, regularly calibrate the position feedback device of the electric actuator to ensure its accuracy and reliability.

10. Safety First: Pay attention to safety during maintenance and upkeep. Adhere to relevant operational procedures and safety requirements. Ensure a safe work environment and take necessary protective measures.
