Maintenance Tips and Best Practices

To ensure long service life, users should follow these maintenance guidelines:

• Regular Inspection – Check seals and seats for signs of wear or leakage.

• Lubrication – Apply lubricant to the stem and worm gear (if manual actuator is used).

• Cleaning – Keep external surfaces free of dust, dirt, and moisture buildup.

• Seal Replacement – Replace seats and gaskets if they show cracks or hardening due to condensation cycles.

• Torque Check – Ensure actuator torque matches manufacturer specifications.

Usage Recommendations

1. Proper Storage Before Installation

• Store in a dry, well-ventilated area to avoid premature condensation damage.

• Keep valve ends sealed with protective covers.

2. Installation Guidelines

• Align the valve centrally between flanges to prevent leakage.

• Avoid excessive tightening of flange bolts, which may deform the seat.

3. Operational Recommendations

• Open and close the valve gradually to prevent pressure surges.

• Do not exceed the recommended operating temperature and pressure.

4. Industry-Specific Advice

• In HVAC systems, select EPDM seats for better temperature resistance.

• In chemical plants, opt for PTFE seats for superior corrosion resistance.
