Maintenance Tips
-
Regular Cleaning: Wipe the valve's exterior with a damp cloth to remove dust and debris.
-
Inspect for Leaks: Check for any signs of leakage around the valve's seals and connections.
-
Monitor System Pressure: Ensure that the system pressure remains within the valve's specifications.
-
Check Calibration: Verify that the valve's presetting matches the system's requirements.
-
Exercise the Valve: Operate the valve from full open to full close position for at least three (3) cycles to ensure smooth operation.
-
Inspect Seals: Annually, check the O-rings and internal seals for any signs of degradation or contamination.
-
Protect from Freezing: If the valve is installed in an area susceptible to freezing temperatures, ensure that it is properly insulated or drained to prevent freeze damage.
