 Installation and Maintenance

Installation

1. Check valve appearance for damage and flexible operation before installation
2. Clean impurities inside pipelines to avoid seal surface damage
3. Install according to flow direction mark, tighten flanges evenly
4. Conduct pressure test after installation to check sealing performance
5. Wire and debug electric/pneumatic actuators before use

Maintenance

1. Regularly check valve opening/closing status and seal leakage
2. Clean debris in valve cavity regularly to prevent jamming
3. Lubricate and calibrate actuators in accordance with specifications
4. Replace seals in time when worn or aged
5. Open and close periodically if long-term idle to avoid rust and jamming
